  The language analysis unit 330 performs natural language processing on the voice uttered by the user from the terminal device 100. The language analysis unit 330 acquires a search query based on the result of natural language processing. The language analysis unit 330 determines whether or not information corresponding to the result of the natural language processing is registered in the facility database 370. When the information corresponding to the result of the natural language processing is registered in the facility database 370, the language analysis unit 330 generates the registered information as a search query. If the information corresponding to the result of the natural language processing is not registered in the facility database 370, the language analysis unit 330 notifies the dialogue response unit 320 that the search query cannot be acquired.

  4 and 5 are diagrams showing an example of the facility database 370. FIG. The facility database 370 stores tree-structured search conditions for each independent search category. An independent search category includes a group of search conditions of different types such as facility type (category), purpose of use, or distance. Types of facilities include restaurants, public facilities, and commercial facilities. The purpose of use includes family members, dates, and entertainment.

  As shown in FIG. 4, the facility database 370 is information in which information is hierarchically associated with “restaurant” as a vertex for each facility category. In the facility database 370a shown in FIG. 4, search conditions such as “restaurant”, “ramen”, and “cafe” are associated with lower layers of restaurants. For example, “luxury store”, “standard store”, and “cheap store” are linked to the lower layer of “restaurant”. For example, information including the location of the restaurant A, information including the location of the restaurant B, and information including the location of the restaurant C are associated with the lower layer of the “cheap store”. In the facility database 370b shown in FIG. 5, for example, “luxury store”, “standard store”, and “cheap store” are linked to the lower layer of the purpose of use. For example, information including the location of the restaurant X, information including the location of the restaurant Y, and information including the location of the restaurant Z are associated with the lower layer of the “standard store”.

  The facility search unit 340 searches for a facility based on the search query acquired by the language analysis unit 330. The facility search unit 340 narrows down the facilities based on the search query from the facilities included in the map information within a predetermined range from the reference position. The reference position is the current position of the user, but is not limited to this, and may be a position designated by the user. The position designated by the user is, for example, the center position of the map after scrolling the map.

[2. Refinement process]
FIG. 6 is a diagram illustrating an example of the map content 112 in the embodiment. The map content 112 is displayed by the user IF unit 110 based on information transmitted from the map search server 300 to the terminal device 100. The map content 112 includes a map 112a, a chat window 112b, and a facility icon 112c. The chat window 112b includes the recognition result of the voice uttered by the user and the question provided by the map search server 300. The recognition result of the voice uttered by the user and the questions provided by the map search server 300 are arranged in time series.

  In FIG. 6A, the map search server 300 provides a question “What is the facility category?” Next to “No good store nearby?” As the recognition result of the voice uttered by the user, The map search server 300 provides a question “What is the distance?” And the map content when the user answers “300 meters”.

  For example, when the user replies “food”, the facility search unit 340 searches for facilities using “food” as a search condition. When the user answers “300 meters”, the facility search unit 340 narrows down the search results using “food and drink” as the search condition, with “300 meters” as the search condition. Thereby, the facility search unit 340 acquires the location information of the facility included in the narrowing-down result from the facility database 370, and displays the map content 112 including the facility icon 112c.

  FIG. 6B is a diagram illustrating an example of the map content 112 when facilities included in the map content of FIG. 6A are further narrowed down. In response to providing the question “What is the purpose of use?” In response to the user answering “Lunch with 5 friends”, the facility search unit 340 further specifies the result of the refinement as “Lunch with 5 friends”. Filter by search criteria. Thereby, the facility search unit 340 can provide facility icons 112c that are narrower than the facility icons 112c included in FIG. 6A, as shown in FIG. 6B.

[3. Processing of map search system 1]
FIG. 7 is a sequence diagram showing a flow of processing in the terminal device 100 and the map search server 300 in the map search system 1 of the first embodiment.

  First, the terminal device 100 starts a map application based on a user operation. The terminal device 100 transmits login information to the map search server 300 (S1). The login information is information including a user ID and a user password, for example. The login information is received by the login server 200. The login server 200 performs user authentication processing based on the login information. The map search server 300 provides a map application service to the authenticated user based on the authentication result of the user authentication process.

  Next, for example, the terminal device 100 periodically transmits the position information acquired by the position acquisition unit 120 to the map search server 300 (S2). Next, the terminal device 100 receives an inquiry from the user (S3), and transmits a search request to the map search server 300 (S4). The question from the user is the voice uttered by the user. For example, when the terminal device 100 receives a user's voice saying “Is there a good store nearby”, the terminal device 100 receives an inquiry from the user. Further, when the position information does not move from a certain range (several meters) for a predetermined period (for example, 3 minutes), the terminal device 100 emits a voice “What are you looking for?” By the map application. A voice uttered by the user for the voice may be received. The terminal device 100 includes the information indicating the inquiry from the user in the search request and transmits it to the map search server 300.

  The map search server 300 receives an inquiry from the user through the dialogue response unit 320. The dialogue response unit 320 sequentially issues questions regarding independent search categories to the user in response to questions from the user (S5, S9). A question related to an independent search category is a question whose answer to a question does not overlap with answers to other questions. Questions about independent search categories include, for example, questions that answer the category of the facility, questions that answer the distance from the current location, and questions that answer the purpose of use. The dialogue response unit 320 first issues a question (1) “What is the facility category?” (S5), and then issues a question (2) “What is the purpose of use?” (S9). .

  Thereafter, the map search server 300 sequentially receives answers from the terminal device 100 in response to the questions being issued in sequence (S6, S10). The language analysis unit 330 first obtains an answer (1) “restaurant” to the question (1) “What is the category of the facility?” (S6). Further, the language analysis unit 330 obtains an answer (2) “Lunch with friends” in response to the question (2) “What is the purpose of use?” (S10).

  The language analysis unit 330 acquires a search query based on the answer (1) obtained by the dialogue response unit 320. The language analysis unit 330 acquires a search query “restaurant” by natural language processing. The facility search unit 340 extracts a facility database 370a including “restaurant” as a keyword from the facility database 370 based on the search query “restaurant” (see FIG. 4). The facility search unit 340 acquires the location information of the restaurant registered in the lower layer of the restaurant in the facility database 370a (S7).

  The map content providing unit 310 transmits the restaurant location information acquired by the facility search unit 340 to the terminal device 100 as a search result (1) (S8). Thereby, the map search server 300 provides the map content 112 including the facility icon 112c at the position corresponding to the location information of the restaurant.

  The language analysis unit 330 acquires a search query based on the answer (2) obtained by the dialogue response unit 320. The language analysis unit 330 acquires a search query “lunch with friends” by natural language processing. The facility search unit 340 extracts a facility database 370b including “friend” or “lunch” as a keyword from the facility database 370 based on the search query “friend and lunch” (see FIG. 5). The facility search unit 340 narrows down the facilities (for example, restaurants) registered in the lower layer of “friend” or “lunch” in the facility database 370b among the restaurants registered in the facility database 370a (S11).

  The map content providing unit 310 transmits the restaurant location information narrowed down by the facility search unit 340 to the terminal device 100 as a search result (2) (S12). Thereby, the map search server 300 provides the map content 112 including the facility icon 112c narrowing down restaurants.

  In response to the inquiry from the user, the dialogue response unit 320 may sequentially issue questions regarding the search categories related to each other (S5, S9). The questions related to the search categories that are related to each other are questions that answer questions related to each other. The questions regarding the search categories related to each other include, for example, a question for answering the facility category and a question for answering the details of the answered facility category. The dialogue response unit 320 first asks "Are you looking for a restaurant?", Then asks "Is it a lunch?", And then says "Is it Western or Japanese?" Ask questions. Thereby, the dialogue response unit 320 can sequentially acquire the search conditions from the broad sense to the narrow sense, and narrow down the facilities in stages.

(3.1 Example of processing to expand the facilities to be guided)
The dialogue response unit 320 is not limited to a question for obtaining a search condition in a narrow sense from a broad sense, and may issue a question for obtaining a search condition in a broad sense in response to a question or answer from a user. When the dialog response unit 320 obtains a question or answer “I want to go to XX” from the user, the dialog response unit 320 may transmit a question that makes a response of a facility or purpose of use wider than XX. For example, when the dialogue response unit 320 obtains a question or answer “I want to eat grilled meat” from the user, the dialogue response unit 320 transmits a question that answers the purpose of use, “Are you hungry?” Also good. As a result, the map search server 300 can change the search result from the facility searched using “baked meat” as the search condition to the facility searched using the purpose of use as the search condition. That is, the map search server 300 can change the facilities to be guided to be wide rather than narrowing down the facilities to be guided.

(3.2 Give priority to facilities based on advertising fees)
The map search server 300 may present a specific facility with priority over other facilities among the narrowed-down facilities. For example, the map search server 300 determines whether there is a facility paying an advertisement fee among a plurality of narrowed down facilities. Whether or not the advertising fee is paid is associated with the location of the facility in the facility database 370, for example. The map search server 300 changes the map content 112 so that when there is a facility that has paid an advertising fee among a plurality of narrowed down facilities, the facility that has paid the advertising fee is displayed more emphasized than other facilities. To do. Thereby, the map search system 1 has the merit that it can be profitable with the advertisement fee for the provider providing the map application service.

(3.3 Presentation of facilities providing benefits)
For example, the map search server 300 determines whether there is a facility that provides privilege information such as a discount coupon among a plurality of narrowed-down facilities. Whether or not privilege information is provided is associated with the location of the facility in the facility database 370, for example. When there is a facility that provides privilege information among a plurality of narrowed down facilities, the map search server 300 changes the map content 112 to display that there is privilege information near the facility icon 112c. Thereby, there is a merit that convenience for the user who uses the map application service is increased. For businesses that provide facilities, there is a merit that the effect of attracting customers can be enhanced.

(3.4 Presentation of reservable facilities)
For example, the map search server 300 determines whether or not a reservation system can make a reservation among a plurality of narrowed down facilities. Whether or not the reservation system can make a reservation is associated with the location of the facility in the facility database 370, for example. The map search server 300 changes the map content 112 to display the fact that the reservation is possible near the facility icon 112c when the reservation system can make a reservation among the narrowed down facilities. Thereby, the map search system 1 has the merit that the convenience is high for the user who uses the map application service, and the merit that the use efficiency of the facility can be increased for the business operator of the facility.

[4. Effect of First Embodiment]
According to the map search system 1 of 1st Embodiment demonstrated above, based on the interaction with a user, it can narrow down in steps from the already guided facility information. Thereby, according to the map search system 1, even if the user cannot recognize the purpose of use of the facility, the facility name, etc. in advance and accurately translate it into a language, and no clear condition is indicated by the user, The result of the search can be guided.

  According to the map search system 1 of the first embodiment, questions regarding independent search categories are sequentially issued to the user. Therefore, for the user, the user can interact with one question while being aware of one answer. These thoughts are organized, and search results that match the user's wishes can be presented.

  According to the map search system 1 of the first embodiment, questions regarding search categories that are related to each other are sequentially issued to the user, so that, for example, a narrowly defined question can be asked after a broadly defined question. According to the map search system 1, it is possible to suppress narrowing down of specific facilities at the beginning of the facility search, and it is possible to present a wider range of candidate facilities as search results.

Second Embodiment
Hereinafter, a second embodiment will be described. In the description of the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

[5. Configuration of map search system 1A]
FIG. 8 is a block diagram illustrating an example of a map search system 1A according to the second embodiment. The map search system 1A includes a terminal device 100B and an SNS server 400 in addition to the map search system 1 of the first embodiment. The terminal device 100A is a terminal device similar to the terminal device 100 in the first embodiment, and performs communication between the map search server 300 and the SNS server 400. The terminal device 100B is a terminal device played by a user different from the user of the terminal device 100A, and performs communication with at least the SNS server 400.

(5.1 SNS server)
The SNS server 400 is a server device that provides a social networking service (hereinafter referred to as SNS). The SNS server 400 includes a service providing unit 410 and a member information database 420, for example.

  The service providing unit 410 provides SNS content for providing SNS. The member information database 420 is realized by an HDD, a flash memory, a RAM, a ROM, or a hybrid storage device combining a plurality of these. Further, part or all of the member information database 420 may be an external device accessible by the SNS server 400, such as a NAS or an external storage server. The member information database 420 stores, in the user ID, attribute information such as a user profile, information such as a virtual communication group in the SNS to which the user belongs, a message transmission / reception history between users, and the like.

  The user ID in the member information database 420 is associated with the user ID in the user information database 210. The SNS server 400 can specify a user who is using the SNS based on the user ID supplied from the map search server 300. In the following description, the user ID in the user information database 210 and the user ID in the member information database 420 are assumed to be the same.

[6. Processing of map search system 1A]
(6.1 Processing Based on Dialogue Between User and Dialog Response Unit 320)
FIG. 9 is a sequence diagram showing a flow of processing in the terminal device 100A, the map search server 300, the SNS server 400, and the terminal device 100B in the map search system 1A of the second embodiment.

  First, the terminal device 100A activates the map application based on a user operation. The terminal device 100A transmits login information to the map search server 300 (S1). The login server 200 performs user authentication processing based on the login information. The map search server 300 provides a map application service to the authenticated user based on the authentication result of the user authentication process.

  Next, for example, the terminal device 100A periodically transmits the position information acquired by the position acquisition unit 120 to the map search server 300 (S2). Next, the terminal device 100A receives an inquiry from the user (S3), and transmits a search request to the map search server 300 (S4). The question from the user is the voice uttered by the user.

  Thereafter, the map search server 300 sequentially receives answers from the terminal device 100 in response to the questions being issued in sequence (S6). The map search server 300 narrows down the facilities in stages by receiving the answers sequentially (S7). The map search server 300 transmits the search results (1) and (2) including the narrowed facilities to the terminal device 100A (S8).

(6.2 Processing of SNS Server 400 and Terminal Device 100B)
The map search server 300 receives an inquiry from the user through the dialogue response unit 320. The dialogue response unit 320 transmits an answer request to the SNS server 400 (S20). The map search server 300 includes the user ID and the inquiry from the user (interaction information) in the answer request. The map search server 300 issues questions to the user sequentially in a state where no answer is obtained from the related user in response to the answer request (S5). That is, the map search server 300 performs a process of transmitting an answer request to the SNS server 400 and obtaining an answer from the related user in parallel with a process of sequentially issuing questions to the user and obtaining an answer from the user. The process of transmitting a part of the dialog from the map search server 300 to the SNS server 400 and obtaining an answer from the related user functions as a dialog unit in which the related user and the map search server 300 perform a dialog.

  The dialogue information may include an inquiry from the user, but is not limited to this, and it is only necessary to include at least a part of the question transmitted to the terminal device 100A and the answer received from the terminal device 100A. The response request may include information obtained by transforming the question or answer from the user into the question to the related user as the dialogue information. For example, when the dialogue response unit 320 accepts “no good restaurant?” As an inquiry from the user, the dialogue response unit 320 is searching for a eating point near △ Δ (place). Include "conversation information" in the response request.

(6.2.1 Selection of related users based on communication groups)
When the SNS server 400 receives the answer request, the SNS server 400 specifies the related user based on the user ID (S21). FIG. 10 is a diagram illustrating an example of information included in the member information database 420. The member information database 420 is information in which an ID in the SNS is associated with a user ID. The user with the user ID “1” is associated with ID-1 of the communication group (1). The user with the user ID “2” is associated with ID-2 of the communication group (2). The user with the user ID “3” is associated with ID-3 of the group (1) and the communication group (3). A communication group in SNS is a group formed by a plurality of users having the same attribute. The attributes of the communication group include, for example, hobbies and preferences.

  The SNS server 400 refers to the member information database 420 and identifies related users based on the user ID. FIG. 11 is a diagram for explaining the transmission of conversation information to related users in the second embodiment. The SNS server 400 transmits inquiry information including a dialogue about the user ID “1” to related users belonging to the same communication group as the user having the user ID “1” (S22). The SNS server 400 refers to the member information database 420 and transmits inquiry information including a dialogue about the user ID “1” to related users with the user ID “x” and the user ID “3” (S22). ). Thereby, the map search server 300 inquires the related user about the user's inquiry.

  The SNS server 400 may identify a user who belongs to another communication group to which a user who is subscribed to the same group as the communication group to which the user is subscribed as an associated user. The user with the user ID “3” belongs to the communication group (3) in addition to the communication group (1).

The SNS server 400 acquires a history of user location information and a history of location information of related users from the location information database 360. When there is a commonality between the current location of the user and a place frequently visited by a plurality of related users, the SNS server 400 identifies the common user as the related user. For example, the SNS server 400 specifies a user whose work location is near the current position of the user as a related user. Thereby, the SNS server 400 can obtain reply information from a user who is familiar with the area where the user is looking for a facility.

(6.2.6 Selection of related users based on attributes)
The SNS server 400 may select a related user who transmits dialogue information from a plurality of related users based on the relationship between the user attribute and the related user attribute. Examples of the user attribute include a category of eating points preferred by the user and a price range. The SNS server 400 may determine the attribute based on the history registered in the member information database 420, or may acquire the attribute information registered in the user information database 210. The SNS server 400 identifies a user whose attribute is close to the user among the plurality of related users as the related user. Thereby, the SNS server 400 can transmit inquiry information to the related user who may reply the facility which a user likes. Specifically, dialogue information can be preferentially transmitted to related users who like cafes in response to questions or answers from users who like cafes.

(6.2.7 Combination of related user selection processing)
Any of the related user selection processes described above may be executed in combination with at least one of the other related user selection processes.

  When the terminal device 100B receives the inquiry information, for example, in the SNS content provided by the SNS server 400, the terminal device 100B presents that a message has been received from the user (S23). When the terminal device 100B receives an answer based on the operation of the related user, the terminal device 100B transmits the answer information to the SNS server 400 (S24). The SNS server 400 returns the response information received from the terminal device 100B in response to the response request (S25).

  When the map search server 300 receives the answer information from the SNS server 400, the map search server 300 transmits the answer of the related user to the user (S26). When the terminal device 100A receives the answer information, for example, the information such as the name and ID of the related user and the answer from the related user are presented as an image or sound. Thereby, the map search server 300 transmits the answer received from the related user to the user.

[7. Other processing example of map search system 1A]
(7.1 Present response information)
FIG. 12 is a diagram illustrating another example of the map content 112. The terminal device 100A provides the map content 112 including, for example, “Mr. XX” as the name of the related user and “There is a delicious Italian in the AA building” as an answer received from the related user in the chat window 112b #. can do.

(7.2 Change the number of facilities to be presented based on response information)
When the map search server 300 obtains an answer from the related user, the map search server 300 may reduce the number of displayed facilities narrowed down by the dialogue between the dialogue response unit 320 and the user. For example, it is assumed that the display number of facilities narrowed down by the dialog between the dialog response unit 320 and the user is five, and five facilities recommended by answers from related users are included. In this case, the map search server 300 may present three cases including facilities recommended by related users.

(7.3 Narrow down facilities based on response information)
The map search server 300 may narrow down facility information based on answers from related users. For example, when the voice information “There is delicious Italian in the AA building” is received as answer information, the map search server 300 extracts the search condition “Italian” by the language analysis unit 330. The facility search unit 340 narrows down facilities based on “Italian” as a search condition extracted by the language analysis unit 330. The map content providing unit 310 provides the user with map content 112 that presents the narrowed facilities.

(7.4 Facilities based on dialogue and facilities based on response information are presented in parallel)
The map search server 300 may provide the map content 112 that presents in parallel the facilities narrowed down by the dialog between the dialog response unit 320 and the user and the facilities searched based on the answer information. For example, the map search server 300 presents the facility searched based on the answer information that the facility is recommended by the answer obtained from the related user. Thereby, the map search server 300 can visually distinguish the search results.

(7.5 Processing to provide dialogue information to communication services other than SNS)
In addition, in 2nd Embodiment, although the user who is related by SNS was specified as a related user, it is not limited to this, The service which can communicate between users may be sufficient. Services that allow users to communicate with each other may be, for example, a mini blog service, a blog service, an electronic bulletin board service, or a mail service that transmits and receives electronic mail. Based on the interaction information, the map search system 1A specifies related users in a server device of a service that allows users to communicate with each other, and provides inquiry information to the specified related users. Thereby, the server apparatus can perform processing such as transmitting an answer from the related user to the user.

(7.6 Process for transmitting dialogue information without specifying related users)
Furthermore, in 2nd Embodiment, although the SNS server 400 acquired the reply received from the related user, and transmitted to the map search server 300, it is not limited to this, A related user is not specified, but a user is personal. The dialogue information may be posted to a server device that provides a community service such as a blog service or an electronic bulletin board service being used. The server device can perform processing such as transmitting a comment or answer to the posted dialogue information to the user.

[8. Effect of Second Embodiment]
According to the map search system 1A of the second embodiment described above, the related information is transmitted to the related user including the inquiry to the user or at least a part of the user's answer, and the related user's answer is acquired. The user's answer can be transmitted to the user. By the way, since conversations using mechanical algorithms such as chatbots are routine and lack flexibility, they may lack humanity. In addition, it is difficult to recommend a facility suitable for the user in consideration of attributes such as the user's actual hobbies and preferences. On the other hand, according to the map search system 1A, at least a part of the dialogue is transmitted to the related users while the dialogue is being performed by the map search server 300. Thereby, according to the map search system 1A, in addition to presenting the facility search result through interaction with the map search server 300, the map search system 1A obtains answers from related users who know the user's hobbies and preferences and presents them to the user. Or generate search results.

  Moreover, according to the map search system 1A, it is possible to obtain answers from a plurality of related users by transmitting inquiry information to a plurality of related users in the same communication group as the communication group to which the user belongs. Moreover, according to the map search system 1A, an answer from a related user can be obtained in a short time.

  Furthermore, according to the map search system 1A, an answer can be obtained from a user of a communication group to which a related user who belongs to a plurality of communication groups belongs in the SNS. Thereby, according to the map search system 1A, in addition to being able to obtain a plurality of answers in a short time, various answers can be obtained.
