The information processing apparatus 1 is communicably connected to one or more information processing terminals 2 via a wired or wireless network. Here, a case where three or more information processing terminals 2 are provided will be described as an example. For convenience of explanation, the three information processing terminals 2 are indicated by information processing terminals 2a to 2c. However, the number of information processing terminals 2 connected is not limited. Further, the information processing terminal 2 is not necessarily the same model or the like as long as it has a similar configuration.

  The information processing apparatus 1 includes a transmission management information storage unit 11, a reception unit 12, a group management information storage unit 13, a browsing management information storage unit 14, a related user identification information acquisition unit 15, a map information storage unit 16, and a spot information acquisition unit 17. , An output unit 18 and a transmission information receiving unit 19.

  The information processing terminal 2 includes a current location information acquisition unit 20, a reception unit 21, a transmission unit 22, a spot information reception unit 23, and a spot information output unit 24.

  The transmission management information storage unit 11 stores a plurality of transmission management information including transmission information and user identification information of the user who transmitted the transmission information. The transmission information is information transmitted to the SNS by a plurality of users using a social network service (hereinafter referred to as SNS).

  SNS (Social Network Service) is a service that forms, supports, or promotes connections between people via a network such as the Internet, for example. It may also be considered as a service for building a community via the Internet. Alternatively, it may be considered a community-type membership service. In SNS, services are usually provided to users registered in SNS. The SNS user is, for example, a registered user of SNS.

  The transmission information is information transmitted by each SNS user (user) from the information processing terminal 2 used by each user to, for example, a server device that provides the SNS. The server device that provides the SNS is, for example, the information processing device 1. The transmission information is, for example, an information sharing service for sharing information such as so-called blogs and miniblogs provided by SNS, photos provided by SNS, and information sharing such as restaurants provided by SNS. Information uploaded for a service or the like. The transmission information is information having at least one of text or an image, for example. The image information here may be a still image or a moving image. The transmission information may include information indicating attributes of information to be transmitted, for example, so-called tag information. The information indicating the attribute is, for example, information indicating the genre, category, topic, interest, etc. of the transmission information. The attribute information may be given as a tag or the like to the transmission information by the user, for example. Such a tag may be considered to constitute a part of transmission information. In addition, the transmission information can identify information indicating the point where the transmission information is transmitted, for example, information on the coordinates of the transmitted point and the point information on the transmitted point with respect to other information in the transmission information. You may have. For example, you may have the information of the coordinate of a point, and point information as the information of the tag provided to transmission information. Tag information, which is point information in this case, may be considered as information included in transmission information. Details of the point information will be described later.

  The user identification information is identification information of the user who transmitted the transmission information. For example, the user identification information is the user's name, membership number, user's email address, mobile phone number, and the like. It may be an account that is used when logging in.

  The process in which transmission information is memorize | stored in the transmission management information storage part 11 is not ask | required. Here, as an example, a case where transmission management information including transmission information and user identification information received by a transmission information receiving unit 19 described later is accumulated in the transmission management information storage unit 11 will be described as an example. However, transmission management information read from a storage medium (not shown) or transmission management information input via an input device may be stored in the transmission management information storage unit 11.

  The transmission management information storage unit 11 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium. The same applies to the other storage units described below.

  The receiving unit 12 receives designated user identification information that is user identification information of one user and current location information that is information on the current location of the user corresponding to the designated user identification information. One user is, for example, one user among a plurality of users (users) using SNS. For example, the receiving unit 12 receives designated user identification information and current location information transmitted from one information processing terminal 2 via a network or the like. The current location information is usually coordinates indicated by a combination of latitude and longitude, but other information may be used as long as the current location can be specified. The location name, address, and building name corresponding to the current location Or information such as a landmark name may be used. The receiving unit 12 may further receive one or more keywords from the one information processing terminal 2 or the like together with the designated user identification information and the current location information. The keyword is a character string. Here, one or more characters are considered as a character string. The same applies to the following. In addition to the keyword, the receiving unit 12 may receive a search operator or the like used for a normal search or the like. The search operator is, for example, information that specifies whether or not one or more keywords are included, or information that specifies whether two or more keywords are used as an AND condition or an OR condition.

  The receiving unit 12 is usually realized by a wireless or wired communication means, but may be realized by a means for receiving a broadcast. The receiving unit 12 may or may not include a communication device.

  The group management information storage unit 13 stores one or more group management information. The group management information is information for managing a group, and includes one or more pieces of user identification information. The group may be considered as a group of users indicated by the user identification information. The group management information may be information that can manage one or more user identification information belonging to the group as a result. The group management information is information having a user ID and a group ID in association with each other, for example, and having the same group ID in association with different user IDs belonging to the same group. The group management information is information for managing group management information belonging to one group with one record.

  The browsing management information storage unit 14 stores one or more browsing management information. The browsing management information is information having one user identification information and browsing user identification information which is user identification information of a user who requests browsing of transmission information transmitted by the user indicated by the user identification information. The user who requests browsing is, for example, a user who follows the transmission information of a so-called one user. Usually, one user and a user who requests browsing are users of the same SNS, preferably a registrant (registered user). An SNS registrant may be considered as a user who has registered for SNS use or a user registered in a server device that provides SNS. The browsing management information stored in the browsing management information storage unit 14 is, for example, one user identification information and browsing user identification information that is user identification information of a user permitted to browse transmission information transmitted by the user identification information. It is preferable that the information includes: For example, a user whose browsing is permitted is a user who is allowed to follow.

  The related user identification information acquisition unit 15 acquires related user identification information that is one or more user identification information highly related to the designated user identification information received by the reception unit 12. The user identification information that is highly related to the designated user identification information is user identification information of a user that is highly relevant to the user indicated by the designated user identification information.

  Here, as an example of processing for acquiring related user identification information, the related user identification information acquisition unit 15 uses (1) transmission information associated with each user identification information included in the transmission management information to perform related user identification. In the case of acquiring information, (2) a case of acquiring user identification information of the same group as the designated user identification information as related user identification information will be described.

(1) When acquiring using transmission information The related user identification information acquisition unit 15 includes the appearance of a character string included in transmission information associated with the same user identification information among transmission information included in transmission management information. According to the situation, related user identification information is acquired from the user identification information included in the inter-transmission link information.

  For example, the related user identification information acquisition unit 15 acquires the appearance status of the character string included in the transmission information associated with the user identification information for each user identification information included in the transmission management information, and according to the appearance status The related user identification information for the designated user identification information is acquired. The character string here is, for example, a character string that satisfies a rule specified in advance. The character string here is, for example, a continuous character group of one or more characters. The rule here is, for example, one or more combinations of conditions or attributes. The character string satisfying the rule specified in advance is, for example, a word of a part of speech specified in advance (for example, a noun, proper noun, etc.), an independent word, a phrase, or the like. The character string designated in advance may be a word (for example, a word including a store, a shop, or the like) including a specific character string (a so-called fixed phrase). Further, the character string satisfying the rule specified in advance may be a tag included in the transmission information. Further, the character string satisfying the rule specified in advance may be a character string associated with a specific item included in the transmission information. The appearance status may be, for example, the number of appearances for each character string (number of total occurrences of the same character string) of the character strings included in the transmission information associated with one user identification information, It may be a determination result of whether or not the number of appearances exceeds a pre-specified threshold value, or the ratio of the number of appearances to the number of appearances of all character strings that satisfy a pre-specified rule. May be. It may be the number of appearances of one or more character strings specified in advance. Further, it may be the type and number of types of character strings that appear. For example, it may be a list of all the character strings that appear.

  The related user identification information acquisition unit 15 acquires the related user identification information according to the appearance status, for example, as follows. For example, the related user identification information acquisition unit 15 uses a common character in a character string included in transmission information corresponding to one user identification information and a character string included in transmission information associated with designated user identification information. If the number of types of common character strings (corresponding to the appearance status) is greater than or equal to a value specified in advance, the one user identification information and the specified user identification information are considered highly relevant. Thus, this one user identification information may be acquired as related user identification information. In this case, the related user identification information acquisition unit 15 repeats this process for other user identification information corresponding to the transmission information.

  In addition, the related user identification information acquisition unit 15, for example, one or more character strings specified in advance for each of the transmission information corresponding to one user identification information and the transmission information associated with the designated user identification information If the number of appearances of the character string having the number of appearances equal to or greater than the threshold matches a predetermined number or more, the one user identification information and the specified user identification information are highly relevant In consideration, this one user identification information may be acquired as related user identification information. In this case, the related user identification information acquisition unit 15 repeats this process for other user identification information corresponding to the transmission information.

  For example, the related user identification information acquisition unit 15 performs, for each character string, a character string included in each of transmission information corresponding to one user identification information and transmission information associated with the specified user identification information. If the number of occurrences is acquired, and each character string having the number of appearances equal to or greater than the threshold is acquired from each character string. The user identification information and the designated user identification information are considered to be highly related, and this one user identification information is acquired as the related user identification information. The related user identification information acquisition unit 15 repeats this process for the user identification information corresponding to the transmission information.

  Further, the related user identification information acquisition unit 15 represents the interest and preference of the user corresponding to each user identification information as a vector by using the number of occurrences of the character string in the transmission information corresponding to each user identification information as a vector component value. The vector may be used to acquire related user identification information highly related to the designated user identification information. Hereinafter, the process which acquires related user identification information using a vector is demonstrated concretely.

  The related user identification information acquisition unit 15 acquires a character string from the transmission information corresponding to one user identification information different from the designated user identification information in the same manner as described above. Similarly, the character string is acquired from the transmission information corresponding to the designated user identification information. Characters appearing in either transmission information corresponding to one user identification information or transmission information corresponding to designated user identification information by performing unique processing (processing for eliminating duplication) from these character strings Get a group of columns. Each character string constituting this group becomes a vector component. And the appearance number of each character string which comprises this group is acquired about each of the transmission information corresponding to one user identification information, and the transmission information corresponding to designation | designated user identification information. Then, the number of occurrences of each character string acquired for one user identification information is used as the component value of the vector of one user identification information, and the number of occurrences of each character string acquired for the specified user identification information is The component value.

For example, if the number of character strings constituting the group is N (N is an integer of 1 or more), and the number of occurrences of each character string in the transmission information corresponding to the user identification information i is represented by u _{i, 1 to} u _{i, N} The vector corresponding to the user identification information i is

となる。

It becomes.

Then, using these component values, the cosine similarity between the vectors is calculated as a value indicating the similarity between the vector of one user identification information and the vector of the designated user identification information. The cosine similarity cos θ _{i, j} between one vector of user identification information i and a vector of designated user identification information _j is calculated by the following equation.

  Further, the related user identification information acquisition unit 15 sequentially performs the same processing as described above for other user identification information different from the designated user identification information, and the user identification information vector and the designated user identification information vector. Cosine similarity is calculated.

Then, the related user identification information acquisition unit 15 acquires user identification information having a large value of cosine similarity cosθ _{i, j} (that is, a short distance between vectors) as related user identification information. The user identification information having a large value here may be user identification information having a cosine similarity value equal to or greater than a predetermined threshold value, and the corresponding cosine similarity value is counted from the largest value, It is good also as user identification information contained by the order designated beforehand.

  In the above example, a character string included in transmission information corresponding to a plurality of user identification information that is a target of detection of related user identification information, and a character string included in transmission information corresponding to designated user identification information, A character string obtained by unique processing may be used as a vector component.

  Here, the appearance status of a combination of a plurality of character strings may be used as the appearance status of the character string. For example, a value obtained by counting the number of occurrences of a combination of a proper noun and a character string indicating evaluation (for example, a character string designated in advance such as “good”, “like”, and “GOOD”) is used. Information indicating the appearance status may be acquired. Alternatively, the number of combinations of one proper noun and a character string indicating a positive evaluation (for example, a character string designated in advance such as “good”, “like”, “GOOD”, etc.) is the same from the number of occurrences. About a proper noun using a value obtained by subtracting the number of occurrences of a combination of a proper noun and a character string indicating negative evaluation (for example, “bad”, “bad”, “BAD”, etc.) For example, when a combination of “curry” and a positive character string such as “delicious” appears, the count value is increased by “1” and “curry” ”And a negative character string such as“ not delicious ”appear, the count value is decreased by“ 1 ”to obtain information indicating the appearance status of“ curry ” .

  In addition, when each piece of transmission information stored in the transmission information storage unit 11 is associated with information on a score indicating evaluation for each piece of transmission information in advance, the number of occurrences of the character string included in the transmission information is determined by this score. The information on the number of appearances weighted in this way may be used when acquiring the information indicating the appearance status as described above. The score information indicating evaluation is, for example, a value obtained by collecting the scores evaluated by the user who has received provision of each transmission information for each transmission information. For example, the total number of times each user who has received transmission information has pressed a button for evaluating transmission information (for example, a button indicating “Good” or a button for adding one evaluation point). There may be. For example, when the score associated with one piece of transmission information is “5 points”, the number of occurrences of a character string satisfying a predetermined rule included in this transmission information may be set to “5”.

  In addition, transmission information whose appearance status is to be acquired includes transmission information having a character string that matches the keyword received by the receiving unit 12 and information (for example, a tag) indicating an attribute that matches the keyword received by the receiving unit 12. You may make it limit to the provided transmission information. For example, when the keyword is “curry” and the character string detected in the transmission information is a store name including “restaurant” or “store”, the related user identification information acquisition unit 15 stores “curry”. It is possible to obtain the appearance status of the name.

(2) When acquiring user identification information of the same group The related user identification information acquisition unit 15 acquires, for example, user identification information included in the same group as the specified user identification information received by the reception unit 12 as related user identification information To do. Specifically, the related user identification information acquisition unit 15, for example, identifies the user included in the same group as the designated user identification information received by the reception unit 12 from the group management information stored in the group management information storage unit 13. Information is acquired as related user identification information. Since the user identification information included in the same group is usually determined to be highly relevant, the user identification information that is highly relevant to the specified user identification information is referred to as the related user identification information based on similar processing. Can be obtained as

  Further, the related user identification information acquisition unit 15 obtains, for each user identification information included in the same group as the designated user identification information received by the receiving unit 12 from the browsing management information stored in the browsing management information storage unit 14. The number of corresponding browsing user identification information is acquired, and among the user identification information included in the same group as the designated user identification information received by the receiving unit 12, user identification information having a large number of acquired browsing user identification information is related user identification. You may make it acquire as information. Thereby, the user identification information of the user who is browsing by many users belonging to the group can be preferentially acquired as the related user identification information. For example, a user who is requested to view transmission information by many users is considered to be a user who provides reliable transmission information or interesting transmission information. By acquiring, more appropriate user identification information of the user can be acquired as related user identification information.

  Note that one or more pieces of user identification information having high relevance may be acquired by processes other than the above (1) and (2). For example, the related user identification information acquisition unit 15 performs a so-called topic extraction process from transmission information associated with the same user identification information in the transmission information included in the transmission management information. Depending on the topic, one or more highly relevant user identification information may be acquired. For example, it is determined whether or not a topic obtained by topic extraction from transmission information corresponding to each user identification information is similar to a topic obtained by topic extraction from transmission information associated with designated user identification information. The user identification information corresponding to the topic determined to be similar is determined to be highly relevant to the designated user identification information. The determination of whether or not they are similar here is, for example, whether or not a predetermined number of character strings obtained by topic extraction match or whether the similarity of sentences obtained by topic extraction is the same. This is determined by comparing the value with a threshold value or the like.

  For topic extraction processing, please refer to the following non-patent literature “Non-patent literature: Megumi Ishii, 2 others,“ Proposal of topic extraction method using noun phrases and word momentum ”, [online] , March 5, 2004, Information Processing Society of Japan, [retrieved on November 22, 2011], Internet <URL: http://ci.nii.ac.jp/elS210002911697.pdf?id=ART0003258384&type=pdf&lang= jp & host = cinii & order_no = & ppv_type = 0 & lang_sw = & no = 1321944202 & cp => ".

  Further, N-gram or the like can be used as processing for detecting the similarity of sentences. Regarding N-grams, refer to the following documents: “" Text analysis using N-gram model ", [October 20, 2011 search], Internet (URL: http://www.shuiren.org) /chuden/teach/n-gram/index-j.html) ".

  The related user identification information acquisition unit 15 can usually be realized by an MPU, a memory, or the like. The processing procedure of the related user identification information acquisition unit 15 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The map information storage unit 16 stores map information. The map information is map information. The map information usually has map symbol information that is an image of a map. The map symbol information is, for example, bitmap data (raster data) or vector data constituting the map, or a combination thereof. The file format of the map symbol information is not limited to the GIF format, JPEG format, PNG format, or the like. The map information may be an ISO kiwi map data format. The map information may include character strings such as place names written on the map, names of buildings, scenic spots, and places.

  The map information includes, for example, positional information indicating an absolute position, such as coordinate information having longitude and latitude of the area displayed by the map information, and the positional relationship between the areas indicated by the respective maps between the map information. It has position information indicating a relative position as can be seen. For example, you may have the positional information which defines the actual range and center point on the ground surface of the map which map information shows with the range of latitude and longitude. Further, for example, position information for managing the coordinates on the map indicated by the map information and the latitude and longitude values of the actual position on the ground surface indicated by the coordinates on the map may be included. The coordinates on the map may be considered as coordinates on the map symbol information. By using such position information, it is possible to appropriately convert coordinates on the map and coordinates (for example, latitude and longitude) on the ground surface (real space).

  Further, the map information may include information (for example, a store name, a building name, a landmark name, a station name, an address, etc.) that identifies a point on the map indicated by the map information. Here, the information specifying the point is referred to as point information. The point information is usually character string information. However, it may be a code number or the like. The point information may be considered to include the area identification information described above. Further, the map information may include point management information having the point information and the coordinates of the point indicated by the point information in association with each other. The coordinates here are, for example, coordinates configured by a combination of latitude and longitude.

  The map information may be managed in association with the scale of the map, for example. Specifically, the map information has information on the scale value of the map output by the map information. Further, the map information may be prepared for each scale. Moreover, you may have several map symbol information from which the map information and the reduced scale about one area | region differ. The scale of the map here may be considered as information indicating the value of the scale of the map.

  The map information may have road information. The road information is information regarding the road indicated by the map. The map information may include so-called link data, node data, and the like. The map information may have other information.

  Here, the term “storage” is a concept including temporary storage. For example, temporarily storing map information acquired (for example, received) from an external server or the like via a network such as the Internet is also considered as storage here.

  The spot information acquisition unit 17 is spot information which is information indicating a spot included in the transmission information associated with the related user identification information, and is specified in advance including the current location indicated by the current location information received by the receiving unit 12. The point information located in the area is acquired from the transmission management information. The area designated in advance including the current location may be any shape, size, or the like as long as it includes the current location. The predesignated region including the current location is, for example, a region where the distance of the current location is equal to or less than the predesignated distance (that is, a region whose radius centered on the current location is a predesignated distance). Further, it may be a rectangular area having a predesignated size centered on the current location. Information for setting the size, shape, and the like of the area designated in advance may be stored in advance by the point information acquisition unit 17 or the like, for example. In addition, the pre-designated area including the current location is a region including the current location (for example, a region indicated by a prefecture, a municipality or a district), or information indicating the outline of the region (for example, coordinates indicating the contour of the region) The area indicated by (information) may be used.

  Hereinafter, two examples of processing in which the spot information acquisition unit 17 acquires spot information will be described. However, you may acquire point information by processes other than the following processes.

  (A) For example, the point information acquisition unit 17 uses the map information stored in the map information storage unit 16 and is associated with coordinates located in a predesignated area including the current location indicated by the current location information. Get one or more point information. As a specific example, the point information acquisition unit 17 is located in a predesignated region including the current location indicated by the current location information using the point management information included in the map information stored in the map information storage unit 16. One or more pieces of point information associated with the coordinates are acquired. For example, it is determined whether or not the coordinates of each point management information are in the area including the current location. If the coordinates are in the area, the point information included in the point management information is stored in a storage medium such as a memory. Read temporarily. And it is judged whether the information (for example, character string etc.) corresponding to each acquired point information is contained in the transmission information matched with the related user identification information which the related user identification information acquisition part 15 acquired. . And the spot information acquisition part 17 acquires the spot information judged to be included.

  Here, the point information acquisition unit 17 acquires the point information in the area including the current location using the map information, specifically, the point management information included in the map information. The unit 17 stores point management information similar to the point management information included in the map information in a storage unit such as a storage medium (not shown), and uses the point management information to store the location management information. The point information may be acquired. Alternatively, the point management information (including the point management information included in the map information) stored in a storage medium such as a server device (not shown) outside the information processing apparatus 1 is used via a network or the like. The point information may be acquired in the same manner as described above.

  Moreover, in the point management information, when the address information of the point is stored instead of the coordinates of the point indicated by the point information, for example, the point information acquisition unit 17 stores the map stored in the map information storage unit 16. Using the information (specifically, using the point management information), the address of the current location indicated by the current location information is the same as the address of the level specified in advance (for example, the address at the municipality level is the same) 1 You may make it acquire the above point information. For example, if the address of the current location is “A prefecture B city C town 1-22 to 33”, one or more pieces of point information including “A prefecture B city C town” as part of the address of the corresponding spot Is acquired from the location management information, and it is determined whether or not the information that matches the acquired location information is included in the transmission information associated with the related user identification information acquired by the related user identification information acquisition unit 15. Anyway. In addition, since the technique for acquiring address information or the like from the coordinates of the current location using map information or the like is a known technique, detailed description of the processing is omitted here.

  (B) The point information acquisition unit 17 acquires one or more pieces of transmission information associated with related user identification information from the transmission management information stored in the transmission management information, and from each acquired transmission information, Detect point information. The point information is acquired according to a rule specified in advance using, for example, one or more prepared phrases or a morphological analysis of a character string. For example, when the restaurant name of the restaurant is acquired as the point information, one or more noun phrases following the character string “restaurant”, one or more noun phrases arranged in front of “store”, and the like are acquired. Alternatively, a point information list may be prepared in advance, and point information that matches the list may be acquired. In addition, in the case where the location information is included in the transmission information in advance so as to be identifiable with respect to other information (for example, when the transmission information includes an item in which the location information is input) The point information acquisition unit 17 may selectively acquire only this point information. Moreover, when the tag which shows point information is provided to transmission information, the point information acquisition part 17 may acquire the tag which shows this point information as point information. Or when the information of the coordinate corresponding to point information is provided so that identification with respect to other information is possible in transmission information, the point information acquisition part 17 acquires the information of this coordinate, and this coordinate The point information and the like may be acquired from the information. For example, the point information associated with the coordinate having the shortest distance from the coordinates (for example, latitude and longitude) assigned to the transmission information may be searched from the point management information.

  And the spot information acquisition part 17 has the coordinate corresponding to the detected spot information, the spot management information which the map information stored in the map information storage part 16 has, the spot management stored in the storage medium which is not illustrated, etc. The information is acquired from a server device (not shown) in which information and point management information connected via a network or the like are stored. And the point information acquisition part 17 determines whether the coordinate corresponding to point information is a coordinate in the area | region containing the present location similar to the above, and if it is a coordinate in an area | region, will acquire the point information To do.

  Also in this case, an address or the like may be used in place of the coordinates as in the case of (a) above.

  The spot information acquisition unit 17 may further acquire spot information included in the transmission information including the keyword received by the reception unit 12 in the above-described spot information acquisition process. The transmission information including the keyword may be transmission information including a character string that matches the keyword received by the receiving unit 12, or a character string that matches the keyword received by the receiving unit 12 is an attribute of the transmission information or the like It may be transmission information given as a tag or the like indicating. Note that the tag attached to the transmission information in this case may be considered part of the transmission information. The match here is usually a complete match, but may be a partial match.

  For example, in the case of the above (a), the point information acquisition unit 17 acquires point information of a point located in a predesignated area including the current location indicated by the current location information, and then acquires the point information and the keyword. Transmission information including both (for example, transmission information including a character string that matches point information and a character string that matches a keyword) associated with the related user identification information acquired by the related user identification information acquisition unit 15 It may be determined whether or not it is included in the information, and if it is included, the point information may be acquired.

  Similarly, in the case of (b) above, the point information acquisition unit 17 is one or more pieces of transmission information associated with related user identification information from the transmission management information stored in the transmission management information. Then, the transmission information including the keyword received by the receiving unit 12 is acquired, the point information is detected from each acquired transmission information, and whether or not the coordinates corresponding to the point information are the coordinates in the region including the current location. If the coordinates are within the area, the point information may be acquired.

  The point information acquisition unit 17 can be usually realized by an MPU, a memory, or the like. The processing procedure of the point information acquisition unit 17 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The output unit 18 outputs the spot information acquired by the spot information acquisition unit 17. For example, the output unit 18 may output a list of spot information acquired by the spot information acquisition unit 17. Further, the output unit 18 may output a map showing the point indicated by the point information acquired by the point information acquiring unit 17 so that it can be identified with respect to other points or regions. You can think of outputting point information. When the output unit 18 outputs a map, the map information stored in the map information storage unit 16 may be read as appropriate. For example, the output unit 18 outputs (for example, transmits) the point information to the information processing terminal 2 that has transmitted the designated user identification information received by the receiving unit 12.

  Moreover, the output part 18 may output at least one part of the transmission information containing the point information to output among the transmission information matched with the related user identification information with point information. Further, a keyword or the like given to the transmission information may be transmitted. Thereby, for example, the user who displayed the spot information can know what explanation or the like the user indicated by the related user identification information is doing with respect to the spot information. Note that when there is a plurality of corresponding transmission information for one piece of point information, a list of these pieces of information may be transmitted together with the point information. Alternatively, on the output side, a plurality of pieces of transmission information corresponding to one point information may be displayed together.

  The output described here refers to display on a display, projection using a projector, printing on a printer, sound output, transmission to an external device, storage in a recording medium, output to another processing device or other program, etc. It is a concept that includes delivery of processing results.

  The output unit 18 may or may not include an output device such as a display or a speaker. The output unit 18 may be implemented by output device driver software, or output device driver software and an output device.

  The transmission information receiving unit 19 receives, for example, transmission information transmitted from the information processing terminal 2 or the like via a network or the like and user identification information of the user who transmitted the transmission information. This transmission information may be given point information of the transmitted point. The transmission information receiving unit 19 accumulates, for example, transmission management information including the received transmission information and user identification information in the transmission management information storage unit 11. The transmission information receiving unit 19 is realized by, for example, a communication unit or a combination of the communication unit and its driver.

  The current location information acquisition unit 20 acquires current location information. The current location information is location information of the current location. The current location information acquisition unit 20 acquires location information of the current location, for example, at predetermined or indefinite timing specified in advance. Further, the current location information acquisition unit 20 may acquire location information of the current location according to a trigger specified in advance. For example, the position information of the current location may be acquired by using a predetermined operation (for example, an operation of pressing any button or the like) as a trigger. The position information is information that can identify the current location such as the latitude and longitude coordinates of the current location and the address of the current location, for example.

  The current location information acquisition unit 20 acquires the location information of the current location, for example, by performing processing similar to that of a GPS (global positioning system) receiver. Further, the position information may be acquired by a process similar to a process for detecting the position of a wireless LAN or a mobile phone. Further, the position information may be acquired by other processing.

  The current location information acquisition unit 20 can be realized by a GPS receiver, for example. Moreover, it is realizable by the structure similar to the process part which performs the position detection of wireless LAN or a mobile telephone.

  The receiving unit 21 receives current location information and designated user identification information. Further, the receiving unit 21 may receive a keyword or the like. For example, the reception unit 21 acquires the latest location information acquired by the location information acquisition unit 20 and accumulated in a storage medium such as a memory (not shown). Acquisition in this case may be considered as reception. However, the reception unit 21 may receive current location information that is input by the user using an input unit or the like. For example, the reception unit 21 receives the user identification information of the user input by the user as the designated user identification information. For example, the receiving unit 21 receives designated user identification information input by a user via an input unit such as a keyboard or a touch panel. The receiving unit 21 stores the designated user identification information once input in a storage medium such as a memory, and reads and receives the specified user identification information stored in the storage medium when input is necessary. You may do it. The receiving unit 21 may further receive one or more keywords input by the user through an input unit such as a keyboard or a touch panel. The receiving unit 21 may receive specified user identification information, keywords, and the like by voice input.

  Moreover, the reception part 21 may receive the input of the user identification information of the user of SNS, and the information for transmitting with respect to SNS. In addition, when receiving such information, the current location information may be acquired (that is, received) from the current location information acquisition unit 20 or the like.

  The input means such as designated user identification information may be anything such as a numeric keypad, a keyboard, a touch panel, or a menu screen. The receiving unit 21 can be realized by a device driver for input means such as a keyboard and a touch panel, control software for a menu screen, and the like.

  The transmission unit 22 transmits the current location information and the designated user identification information received by the reception unit 21 to the information processing apparatus 1. When the receiving unit 21 further receives a keyword, the current location information, designated user identification information, and keyword are transmitted. When the reception unit 21 receives input of user identification information and transmission information that is information to be transmitted to the SNS, the reception unit 21 transmits the information to the information processing apparatus 1. Further, the current location information received by the receiving unit 21 may be added to the transmission information and transmitted.

  The transmission unit 22 is usually realized by wireless or wired communication means, but may be realized by broadcasting means. The transmission unit 22 may or may not include a communication device.

  The spot information receiving unit 23 receives spot information transmitted by the output unit 18 of the information processing apparatus 1. Moreover, when the output part 18 outputs the information of the map which shows point information, the point information receiving part 23 may receive the information of this map, and it may be considered that the point information was received also in this case.

  The point information receiving unit 23 is usually realized by a wireless or wired communication means, but may be realized by a means for receiving a broadcast. The point information receiving unit 23 may or may not include a communication device.

  The spot information output unit 24 outputs the spot information received by the spot information receiving unit 23. For example, the spot information output unit 24 displays the received spot information on a monitor or the like. In addition, when the spot information receiving unit 23 receives map information indicating the spot information, the map information may be output (for example, displayed), and such a case may be considered as an output of spot information.

  The point information output unit 24 may be considered as including or not including an output device such as a display or a speaker. The point information output unit 24 can be realized by driver software of an output device or driver software of an output device and an output device.

  Next, an example of the operation of the information processing apparatus 1 will be described using the flowchart of FIG. Here, an example of acquiring point information using related user identification information acquired using the appearance status of a character string in transmission information will be described. In addition, when performing the process of this flowchart, the group management information storage part 13 and the browsing management information storage part 14 are omissible.

  (Step S201) The receiving unit 12 determines whether or not designated user identification information and current location information have been received. In addition to these, here, as an example, it is determined whether or not a keyword is also received. If received, the process proceeds to step S202. If not received, the process proceeds to step S216.

  (Step S202) The related user identification information acquisition unit 15 determines whether or not a vector having the appearance status of the character string as a component has been acquired for each user identification information. The vector here is the vector acquired and accumulated in step S219 described later. If it has been acquired, the process proceeds to step S203. If it has not been acquired, the process proceeds to step S217.

  (Step S203) The related user identification information acquisition unit 15 is a vector other than the vector corresponding to the designated user identification information received in Step S201 and the designated user identification information associated with the transmission information stored in the transmission management information. A cosine similarity with a vector corresponding to each of one or more pieces of user identification information is calculated.

Obtained as identification information. The acquired related user identification information is temporarily stored in a storage medium (not shown) or the like. The related user identification information acquisition unit 15 performs a process for detecting the related user identification information by comparing the calculated value with a threshold every time the cosine similarity is calculated for one user identification information. The user identification information may be repeated.

  (Step S212) The point information acquisition unit 17 determines whether one or more pieces of point information have been acquired. Here, it is determined whether or not one or more pieces of spot information are stored in a storage medium (not shown) that accumulates spot information in step S209. If one or more pieces of point information can be acquired, the process proceeds to step S213. If not acquired, the process proceeds to step S215.

  (Step S213) The spot information acquisition unit 17 performs a process (so-called unique process) for eliminating duplication in the spot information accumulated in Step S210. Note that the process of eliminating duplication may be omitted.

  (Step S214) The output unit 18 outputs the spot information obtained in step S213. Then, the process returns to step S201.

  (Step S215) The output unit 18 outputs that there is no appropriate point information. Then, the process returns to step S201.

  (Step S216) Is the timing at which the related user identification information acquisition unit 15 acquires a vector corresponding to the appearance status of the character string for each user identification information associated with the transmission information stored in the transmission management information? Judge whether or not. For example, it is determined that the acquisition timing is reached when the date / time specified in advance is reached or when the elapsed time specified in advance elapses. If it is timing, the process proceeds to step S217, and if not, the process proceeds to step S220. Note that it may be determined whether or not a trigger specified in advance has been received, and when the trigger has been received, the process may proceed to step S217.

  (Step S217) The related user identification information acquisition unit 15 increments the value of the counter m by 1.

  (Step S218) The related user identification information acquisition unit 15 sequentially reads each piece of transmission information associated with the mth user identification information, and searches for a character string that satisfies a pre-specified rule from the read transmission information. The number of occurrences of the character string is counted for each character string.

For example, the unique process is performed on all the character strings that appear.

  (Step S223) The related user identification information acquisition unit 15 matches the count number for each character string accumulated for each user identification information in Step S219 with the vectors having all the character strings acquired in Step S222 as components. By assigning the component value corresponding to the character string to be obtained, a vector is obtained for each user identification information. In addition, about the component of the vector corresponding to the character string which does not correspond with the character string accumulate | stored for every user identification information in step S219 among all the character strings acquired by step S222, here, the component The value is set to “0”. Then, the acquired vector is stored in a storage medium (not shown) in association with each user identification information. Then, the process returns to step S201.

  (Step S224) The transmission information receiving unit 19 determines whether or not the transmission information and the user identification information are received. Note that the transmission information receiving unit 19 may receive transmission information to which point information is added. If received, the process proceeds to step S225. If not received, the process returns to step S201.

  (Step S225) The transmission information receiving unit 19 stores the transmission management information including the transmission information and the user identification information received in step S224 in the transmission management information storage unit 11.

The transmission information including the keyword is sequentially detected, and each time such transmission information is detected, the point information included in the transmission information matches one of the point information in the area including the current location acquired in step S205. The point information acquisition unit 17 acquires the point information determined to match, and temporarily stores it in a storage medium or the like (not shown). If one or more pieces of point information are temporarily stored at the time when these processes are completed for all the transmission information associated with the It proceeds to flop S213, if it is not stored, may proceed to step S215.

  In the flowchart of FIG. 2, the process is terminated by powering off or a process termination interrupt.

Then, the process proceeds to step S302.

  (Step S302) The related user identification information acquisition unit 15 uses the browsing management information stored in the browsing management information storage unit 14 to calculate the number of browsing user identification information corresponding to each user identification information detected in step S301. It counts and acquires user identification information with many counts as related user identification information. For example, the related user identification information acquisition unit 15 acquires user identification information whose corresponding count number is greater than or equal to a threshold as user identification information with a large count number. In addition, the related user identification information acquisition unit 15 acquires, as user identification information having a large number of counts, user identification information in which the rank counted from the one with the large number of counts is associated with a count number within a predetermined rank.

Each information processing terminal 2 has a monitor 18a as a display device, and a touch panel (not shown) is provided on the monitor 18a.

  FIG. 5 is a map symbol information management table for managing the map symbol information constituting the map information stored in the map information storage unit 16. The map symbol information management table has items such as “map ID”, “map symbol information”, “latitude”, and “longitude”. “Map ID” is identification information for managing map symbol information. “Map symbol information” is map symbol information, and here, the file name of the map symbol information is indicated. “Latitude” and “longitude” indicate the latitude and longitude of the center of the map indicated by the map symbol information. In the present embodiment, x1, x2,... Indicating latitude, y1, y2,... Indicating longitude, and the like each indicate an actual value. This also applies to the following.

  FIG. 6 is a diagram illustrating an example of the spot management information for managing the spot information included in the map information stored in the map information storage unit 16. The point management information has items of “point identification information” and “coordinates”. “Point identification information” is identification information for identifying one point. Here, it may be considered as point information. “Point identification information” is, for example, the name, address, or the like of a building, a store, a landmark, or the like at one point. “Coordinates” are coordinates that designate the position of one point indicated by the point identification information.

  For example, the user B of the information processing terminal 2b inputs a comment about a store prepared in advance in order to transmit an impression about the store used by the user B to the SNS as shown in FIG. The user identification information “userB” is entered in the user identification information input field 71 and the name of the store that is the input target of the comment “Go Go Ichiban”. In the place name input field 72, and a comment about this store “The curry here is really delicious. Especially, the special curry is the best.” Is input in the comment input field 73, and the send button 74 is pressed. Suppose. Based on the information input on the input screen, the transmission unit 22 uses the user identification information “user ID: userB” and “location name: go-go first, comment: curry here is really delicious. The transmission information “highest” is transmitted to the information processing apparatus 1.

  The transmission information receiving unit 19 of the information processing apparatus 1 receives the user identification information and the transmission information transmitted from the information processing terminal 2 b and accumulates them in the transmission management information storage unit 11. The accumulation here is additional writing.

The transmission management information has items of “user ID” and “transmission information”. In FIG. 8, each record (row) is transmission management information. The “transmission information” further includes items of “location name” and “comment”. “User ID” is user identification information, and for example, a character string after “user ID:” in the user identification information received by the transmission information receiving unit 19 is accumulated. “Transmission information” is transmission information. The “location name” is point information included in the transmission information. From the transmission information received by the transmission information receiving unit 19, the character string “location name:” and the first “,” appearing next. A character string is accumulated. The “comment” is a part other than the point information of the transmission information, and the character string after the character string “comment:” in the transmission information received by the transmission information receiving unit 19 is accumulated. For example, in FIG. 8, the top record is transmission management information including transmission information transmitted by the user B.

  Here, for example, it is assumed that it is time to acquire a vector corresponding to the appearance status of the character string for each user identification information associated with the transmission information stored in the transmission management information. For example, it is assumed that the date and time specified in advance (for example, 5 pm every Friday) is reached. The related user identification information acquisition unit 15 determines that it is time to acquire a vector, and performs processing for acquiring a vector for each user identification information.

  First, the related user identification information acquisition unit 15 acquires the values of “user ID” of all the records of the transmission management information shown in FIG. 8, performs unique processing, and shows user identification information that appears in all the transmission management information To ensure that there are no duplicates. Although all transmission management information is used here, user identification information may be acquired only for transmission management information that satisfies a predesignated condition. For example, information such as the transmission date / time of the transmission management information and the reception date / time is added to the transmission management information, and the transmission including the transmission information transmitted (or received) within a predetermined period according to the date / time. You may make it acquire user identification information only from management information.

  FIG. 9 is a diagram showing user identification information acquired by the related user identification information acquisition unit 15.

  Next, the related user identification information acquisition unit 15 acquires information associated with the item “location name” of all the records of the transmission management information illustrated in FIG. 8, performs unique processing, and performs transmission management. Place name information that is information associated with the item “place name” that appears in all information is acquired so as not to overlap.

  FIG. 10 is a diagram illustrating the place name information (“place name”) acquired by the related user identification information acquisition unit 15. In this specific example, the related user identification information is acquired using a vector for each user identification information obtained by using the appearance status of the place name information that is a character string associated with the item “place name”. I do.

  The related user identification information acquisition unit 15 firstly sets the value “userA” of “user ID” of the first record of the user identification information shown in FIG. 9 and the first of the place name information shown in FIG. “Indian cuisine India”, which is the value of the “location name” of the record of “No.”, for all records whose “user ID” is “userA” in the transmission management information shown in FIG. The number of records that match the “Indian Food India” read above is counted. The count number is stored in a storage medium (not shown) in association with the user ID “userA” and the place name information “Indian Food India”.

  Further, similarly for the “place name” of the second and subsequent records in the place name information shown in FIG. 10, the number of transmission management information having “place name” that matches this “place name” is counted sequentially. To do.

  Then, when the processing for all of the “location names” in FIG. 10 is completed, the transmission management information corresponding to the “user ID” of the second and subsequent records of the user identification information shown in FIG. Also, for each “location name”, the number of records in which the value of “location name” matches the “location name” of each record of the location name information shown in FIG. In association with the value of the “user ID” and the value of the counted place name information (“place name”), similar to the above, it is stored (added here) in a storage medium (not shown).

  As a result, the number of appearances of the local name information shown in FIG. 10 in the transmission information corresponding to each user identification information shown in FIG. 9 can be acquired. The number of appearances of the local name information for each user identification information acquired in this way becomes a vector component for each user identification information.

  FIG. 11 is a place name appearance number management table for managing the number of appearances of each place name information acquired by the related user identification information acquisition unit 15 for each user identification information.

  Here, a vector based on the appearance frequency of the character string (here name information) in the transmission information corresponding to each user (Indian cuisine India count value, Cafe brew count value, Cafe Manday count value, Curry jumbo For example, the count value of the place name “userA” is “2”, “2”, “1”, “1”... In order from the top, and therefore corresponds to “userA”. A vector based on the appearance frequency of a character string (here, name information) in the transmission information is (2, 2, 1, 1...). The vector of “userB” is (1, 0, 0, 0...). The same applies to vectors for other users.

Here, the user A who uses the information processing terminal 2a wants to know information on a restaurant that provides curry recommended by other users who have the same preference as the user A in the vicinity of the current location. The keyword “curry” is input into the keyword input field 12a of the information processing terminal 2a as shown in FIG. 5B, the user ID “userA” of the user A is input into the user ID input field 12b, and the search button 12c is pressed. . The point information receiving unit 23 of the information processing terminal 2a has a GPS function, and immediately after the information processing terminal 2a is activated, for example, every minute, the current location coordinates (combination of latitude and longitude) as current location information. ) Is repeated, and the receiving unit 21 acquires the coordinates (x ₁₀₀ , y ₁₀₀ ) at the time when the search button 12 c is pressed from the point information receiving unit 23. Then, the output unit 18 transmits the user ID, the keyword, and the current location information acquired by the receiving unit 21 to the information processing apparatus 1. The user ID transmitted by the output unit 18 is designated user identification information.

The receiving unit 12 of the information processing apparatus 1 receives the keyword “curry”, the designated user identification information “userA”, and the current location information “(x ₁₀₀ , y ₁₀₀ )” transmitted from the information processing terminal 2a. When the receiving unit 12 receives the designated user identification information, the related user identification information acquisition unit 15 performs a process of acquiring the related user identification information.

  Specifically, as described above, the related user identification information acquisition unit 15 sets a combination of “location name” and “count number” corresponding to “user ID” that matches the specified user identification information “userA”. The vector corresponding to the designated user identification information “userA” is obtained in the same manner as described above by using the place name appearance number management table shown in FIG. 11 and using the pair of “place name” and “count number”. get. The vector corresponding to “userA” acquired here is “(2, 2, 1, 1...)” As described above. Similarly, the related user identification information acquisition unit 15 acquires a vector for each of other user identification information managed in the place name appearance number management table as in the case of “userA”, and the acquired vector, The vector cosine similarity with the vector corresponding to “userA” is calculated using Equation 1 described above. Then, the calculated cosine similarity value is compared with a threshold value prepared in advance, and the value of “user ID” associated with a vector having a value equal to or greater than the threshold value is sequentially acquired as related user identification information. It accumulates in a storage medium that does not. Assume that the related user identification information acquired in this way is “userB” and “userG”.

Next, the spot information acquisition unit 17 uses the current location information received by the reception unit 12 to acquire information indicating a region having a predesignated shape and size including the current location. For example, information indicating a square area on the ground surface having a distance (for example, 500 m) whose one side is designated in advance with the current location (x ₁₀₀ , y ₁₀₀ ) as the center is acquired. For example, here, coordinates indicating the latitude and longitude of the four corners of such a square are acquired.

  Next, the spot information acquisition part 17 acquires the spot information located in the area | region containing the present location set in this way from the spot management information shown in FIG. For example, the value of “coordinate” of one record of each point management information is acquired, and it is determined whether or not this “coordinate” is a coordinate within the region including the current value set above. Only when it is determined that the coordinates are, the “point identification information” associated with the “coordinates” is acquired and stored in a storage medium (not shown). By repeating this process for each record of point management information, it is possible to acquire point identification information (point information) for a point located in the region.

  FIG. 13 is a diagram illustrating the point information that is acquired by the point information acquisition unit 17 and is located in an area including the current location indicated by the current location information.

  The spot information acquisition unit 17 acquires the first spot information “inorganic area” from the spot information in the area including the current location shown in FIG. 13, and from each record of the transmission management information shown in FIG. 8. , “User ID” matches either “userB” or “userG”, “Location name” matches the first point information “Inorganic area”, and the receiving unit 12 receives the “transmission information”. Search for a record containing a character string that matches the keyword “curry”. When a record having a desired value as a condition is detected, a set of “location name” and “comment” included in each detected record is stored in a storage medium (not shown). Here, since a record satisfying the search condition is not detected, a set of “location name” and “comment” is not accumulated.

  Next, the second point information “Go Go Ichiban” is acquired from the point information in the area including the current location shown in FIG. 13, and the user ID “userB” or “userG” is acquired in the same manner as described above. A character string that matches any one of them, matches the “location name” with the second point information “go-go first”, and matches the “curry” that is the keyword received by the receiving unit 12 in the “transmission information”. Search for records that contain it. Here, assuming that two records satisfying this search condition are detected, a set of point information “go-go first” and “transmission information” values included in the two records is a storage medium (not shown). Accumulated in.

  Hereinafter, similarly, the spot information acquisition unit 17 performs the same processing as described above for the third and subsequent spot information in the spot information in the area including the current location illustrated in FIG.

  FIG. 14 is an acquisition point information management table for managing a set of “point information” and “transmission information” acquired by the point information acquisition unit 17.

  And the spot information acquisition part 17 performs the unique process which eliminates duplication of spot information in the acquisition spot information management table | surface shown in FIG. However, different transmission information associated with the same point information is associated with one point information after the unique processing.

  Then, the output unit 18 transmits the set of the spot information and the transmission information obtained by the unique process by the spot information acquisition unit 17 to the information processing terminal 2a that is the transmission source of the designated user identification information.

  When the spot information receiving unit 23 of the information processing terminal 2a receives a set of spot information and transmission information transmitted from the output unit 18, the spot information output unit 24 uses the received spot information as a list to process the information processing terminal 2a. Displayed on the monitor 18a.

FIG. 15 is a diagram illustrating a display example of spot information by the spot information output unit 24.
Then, when a pre-designated operation such as click or tap is performed on one of the listed spot information, the spot information receiving unit 23 is associated with the spot information that is the operation target. One or more pieces of transmission information are displayed on the monitor 18a.

  FIG. 16 is a diagram illustrating a display example of transmission information by the point information output unit 24.

  Here, the spot information is displayed as a list, but the spot information acquisition unit 17 of the information processing apparatus 1 acquires the coordinates corresponding to the uniquely processed spot information from the spot management information shown in FIG. The map symbol information indicated by the current location information is acquired from the map information storage unit 16, and on the position indicated by the coordinates corresponding to the point information on the map symbol information, such as a marker or a pin associated with the point information. You may make it transmit the map symbol information which has arrange | positioned the image to the information processing terminal 2a with point information and transmission information. Then, the point information output unit 24 of the information processing terminal 2a may display the map symbol information on which markers or pins corresponding to the point information are arranged on the monitor 18a. Then, when a predesignated operation such as click or tap is received for the marker on the map symbol information, the point information output unit 24 displays the point information corresponding to this marker and the transmission information on the monitor 18a. May be displayed.

  In such a specific example, for example, by using transmission information provided by a user who uses the same (or affiliated) SNS as one user, another user who has similar preferences and the like as the one user. It is possible to obtain and provide information to a single user by acquiring and providing information on points that other detected users have recommended or introduced near the current location. It is possible to provide appropriate point information that suits the user's preference.

(Specific example 2)
Hereinafter, specific example 2 of the operation of the information processing system according to the present embodiment will be described. Here, a specific example in which the information processing apparatus 1 performs the same operation as the flowchart shown in FIG. 3 using the group management information storage unit 13 and the browsing management information storage unit 14 will be described.

  Processes other than the process of the related user identification information acquisition unit 15 for acquiring the related user identification information are the same as those in the first specific example, and thus detailed description thereof is omitted here. The related user identification information acquisition unit 15 is also omitted from the process of acquiring the place name appearance number management table used for acquiring the vector for each user.

  FIG. 17 is a diagram showing the group management information stored in the group management information storage unit 13. The group management information has items of “group ID” and “user ID”. “Group ID” is group identification information. “User ID” is user identification information. It is assumed that the same group ID is associated with user IDs belonging to the same group.

  FIG. 18 is a diagram showing browsing management information stored in the browsing management information storage unit 14. The browsing management information has items of “user ID” and “browsing user ID”. The “user ID” here is user identification information (user identification information on the browsing side) of the user who is requested to browse (permitted to browse), and the “viewing user ID” is the corresponding “user This is user identification information (user identification information on the browsing side) of a user who requests browsing of transmission information provided by “ID”.

  Assuming that the receiving unit 12 of the information processing apparatus 1 receives the designated user identification information “userA” and the like as in the first specific example, the related user identification information acquisition unit 15 displays the group management information shown in FIG. Then, “G01” which is the “group ID” corresponding to “userA” is acquired. Then, “user ID” other than “userA” associated with the group ID “G01” is acquired from the group management information. The “user ID” acquired here is user identification information belonging to the same group as “userA”.

  FIG. 19 is a diagram illustrating user identification information belonging to the same group as “userA” acquired by the related user identification information acquisition unit 15.

  Next, the related user identification information acquisition unit 15 extracts the first user identification information “userB” of the user identification information shown in FIG. 19, and the “user ID” is “userB” in the browsing management information shown in FIG. 18. "Is counted. Then, the count value is stored in a storage medium (not shown) in association with the user identification information “userB”. Thereby, the number of users (user identification information) who have requested browsing of transmission information provided by the user indicated by “userB” can be acquired. Similarly, the same processing is performed for the second and subsequent “user IDs” of the browsing management information shown in FIG.

  FIG. 20 is a diagram illustrating the number of pieces of user identification information of users who have requested browsing of transmission information provided by the user identification information for each user identification information acquired by the related user identification information acquisition unit 15. “Number of browsing requests” is the number of users who have requested browsing (the number of user identification information).

  And the related user identification information acquisition part 15 detects the record with many values of "the number of browsing requests" in the number of user identification information which requested | required browsing for every user identification information shown in FIG. User ID "is acquired as related user identification information. Here, the “user ID” of the record whose “viewing request count” value is “3” or more is acquired as the related user identification information. Specifically, the related user identification information acquisition unit 15 acquires “userB” and “userH” as related user identification information.

  Since the subsequent processing is the same as in the first specific example, the description is omitted here.

  For example, in SNS, a user who belongs to the same group as one user is considered to have a high possibility of having similar preferences and the like as one user. In addition, it is considered that a user whose transmission information is viewed by many users often has appropriate contents of the transmission information. Therefore, in such a specific example, a user who is in the same group as one user and a large number of users who are requested to view transmission information recommends or introduces near the current location. Since it is possible to acquire information on a certain point and provide it to one user, it is possible to provide appropriate point information suitable for the user's preference to one user.

  As described above, according to the present embodiment, for one user who uses SNS, the point information included in the transmission information associated with the related user identification information having high relevance to the designated user identification information of the user is obtained.
