Next, the search system will be described.
FIG. 4 is a block diagram of the search system. As shown in FIG. 4, the search system is roughly divided into four servers: a collection server 10 as collection means, an index server 20 as index creation means, a search server 30 as search means, and a Web server 40 as transmission means. It is made up of. The search system includes a management server 50 that manages the search system.

  First, the collection server 10 periodically fetches data by visiting Web pages provided by a Web server on a network such as the Internet, and the index server 20 uses a database called an index from character information on these Web pages. make. Based on this index database, the search server 30 executes a search service. The Web server 40 receives a search request from the user, sends it to the search server 30, and sends the returned search result to the user's mobile phone 60.

  The management server 50 is a content information table in which the collection definition file 12 for controlling the content collected by the collection server 10 and the collection start time, and the index creation file 22 used when creating a database in the index server 20 are collected. 51. The management server 50 also includes an administrator Web function 52 that displays the content information table 51, and the administrator manages information in the content information table 51 from the personal computer 100 via the administrator Web function 52. .

FIG. 5 is an example of the content information table 51. The content information table 51 shown in FIG. 5 includes a content ID, a content name, a page address (top URL) for displaying a search result, a content introduction sentence, an address when a keyword is taken over (keyword takeover URL), and a content category. , Exclusion keyword, additional word, deletion word, address to start collecting information (collection start URL), upper limit of the number of link layers (number of collection layers), upper limit number of pages to collect information (collection upper limit page), upper limit of collection time Information such as whether other hosts can be collected, collection schedule (collection start time) (collection cycle), index value increase, and the like are held.
Among these, the exclusion keyword, collection start URL, number of collection layers, collection upper limit page, collection upper limit time, availability of other host collection, collection schedule (collection start time) (collection period) are information of the collection definition file 12. .

  The administrator appropriately changes the content information table 51 on the personal computer 100, and the change information is reflected in the collection definition file 12 and the index creation file 22.

  The collection server 10 includes a robot 11 that is a program that automatically collects HTML files constituting web pages provided by a web server on a communication network such as the Internet, and a collection definition file for controlling the robot 11. 12 and morpheme analysis means 13 for performing morphological analysis on the content information collected by the robot 11.

  Collection of content information by the robot 11 is performed as follows. When the robot 11 first reaches the time (1:30) or period (6h) held in the collection start schedule of the collection definition file 12 composed of part of the information in the content information table shown in FIG. Connect to the URL (http://WWW.aaa.com) held in the collection start URL of the collection definition file 12. When connected to the collection start URL, it is checked whether the information providing server 90a is a legitimate server. When the information providing server 90a is a server connected by the https protocol, it is checked whether the server certificate is valid. If the server certificate is invalid, it connects to the next information providing server 90b.

  Next, the robot 11 checks whether or not the information search server 90a holds the robot search definition file “robots.txt”. Specifically, the robot 11 makes a request to the information providing server 90a, and transmits “robots.txt” from the information providing server 90a. This “robots.txt” holds the user agent name. When the user agent name held in the “robots.txt” is the same as the user agent name held by the robot 11, information is collected for each piece of content information in the information providing server 90a. On the other hand, if the user agent name held in “robots.txt” is different from the user agent name held by the robot 11 or if “robots.txt” is not held, Connect to the information providing server 90b.

  As described above, when it is proved that the information providing server 90a is a legitimate server, it is checked whether the Web page (html file) in the information providing server 90a is information that can be collected.

  FIG. 6 is a check flow of the Web page in the information providing server 90a. As shown in FIG. 6, first, it is checked whether the URL of the Web page is in an expression format (regular expression) compliant with the standard (S1). If the URL is not a regular expression (NO in S1), it will cause a malfunction, so the web page content information is not collected. On the other hand, if the URL is a regular expression, it is checked whether the URL has a specified extension shown in FIG. 7 (S2). If the URL has an extension other than that shown in FIG. 7 (NO in S2), the content information of this Web page is not collected. On the other hand, if the URL has the specified extension shown in FIG. 7 (YES in S2), it is checked from the URL of the Web page whether it is an illegal URL in the exclusion list (S3). If the Web page is the URL of the exclusion list (YES in S3), the content information of this Web page is not collected. If the Web page is not a URL (illegal URL) of the exclusion list (NO in S3), it is determined as a collectable content.

  Further, the robot 11 checks the anchor name of the web page in order to check whether the link destination on the web page is a link destination to be referred to. Anchor names expressed by “<BASE HREF =”... “> ˜ </A>” or “BASE H =“... “> ˜ </A>” are regarded as link targets. On the other hand, “<a...> <IMG SRC =“ ... ”> </a>” or “<a...> <IM SRC =“ ... ”> </a>” Thus, if there is a link to an image file in the anchor, it is regarded as an advertisement and this link destination is not set as a link target. Further, the exclusion word defined in the collection definition file 12 is referred to. For example, when an exclusion keyword such as “meeting” is set in the collection definition file 12, “<a href =” WWW. ddd. com "> Click here for nice encounters <a>". Further, referring to whether or not other hosts can be collected with reference to the collection definition file 12, when “no collection” is set, the link destination is another host (domain) such as “WWW.bbb.com/. If this is the case, this link destination is not a link target.

  In the present embodiment, three layers of information are collected based on the collection definition file 12. In the hierarchy count, the content information of the collection start URL in the collection definition file 12 is regarded as one layer, and the content information linked from this collection start URL is counted as two layers. The content information linked from the content information of the two layers is counted as the third layer. Then, content information having three or more layers is not collected.

  FIG. 8 is a content information collection flow. As shown in FIG. 8, first, it is checked whether or not the diameter exceeds 15 minutes from the start of information collection (S5). If the diameter does not exceed 15 minutes or more (NO in S5), it is checked whether the collection page is 200 pages or more (S6). When the number of collected pages is 200 pages or less (NO in S6), it is checked whether there is still collected information (S7). If there is information, the steps after S5 are repeated. On the other hand, if the diameter is over 15 minutes from the start of information collection (YES in S5), the collection page is 200 pages or more (YES in S6), or there is no collection information (NO in S7), this information is provided The information collection of the server 90a is terminated (S8), and the next information providing server 90b (WWW.bbb.com) is connected.

  Next, the collection server 10 checks whether or not the content information collected by the robot 11 is stored in the collection server 10 as collected content. First, it is checked whether or not the MIME-TYPE of the collected information is the MIME-TYPE shown in FIG. In the case of MIME-TYPE shown in FIG. 7, the <META> tag is checked next to check whether there is a description such as “nofollow” or “noindex”. Collection information that has no description such as “nofollow” or “noindex” and whose <META> tag is a regular expression is stored in the collection server as collection content. On the other hand, if it is not MIME-TYPE shown in FIG. 7 or if the <META> tag is not a regular expression, this collected information is not collected.

  Next, the collection server 10 performs a process of dividing the text information of the content into words by the morphological analysis unit 13 for the collected content stored in the server. If it is a verb, the final form is standard, and the part of speech and usage of the extracted word are obtained by morphological analysis, and each word is converted to the standard form. Thus, the content information subjected to morphological analysis is passed to the index server 20.

  The index server 20 generates a database called an index so that the user can easily find the target page by classifying the collected content subjected to the morphological analysis processing or adding information. The index server 20 includes an index generation unit 21 that generates an index from content information subjected to morphological analysis, and an index creation file 22 that adds additional information to the index.

  First, the index server 20 generates an index table in which words and URLs of content information in which the words appear are paired from the morphological-analyzed content information. At this time, the deletion table of the index creation file 22 is referred to, and no index table is created for the words held as the deletion word. For example, when the word “image system” is set as the deletion word, an index table in which the URL of the content information in which the word “image system” appears is not created.

  Further, the index server 20 adds additional information such as a content ID, a content name, a top URL, a content introduction sentence, and a category obtained from the content information to the index table. Further, the index server 20 adds a necessary word even if there is no word in the contents of the content information so as to be hit at the time of search. For example, even if words such as “New Arrival”, “POP”, and “Indie” are not included in the character information of the content information, the content information content is related to “New Arrival”, “POP”, and “Indie”. If it is content, add these words. The index table to which the additional information is added by the index server 20 is transferred to the database 31 of the search server 30 and stored.

  The search server 30 includes a database 31 and a search unit 32. The database 31 stores index table data. The search unit 32 searches the database 31 based on the keyword obtained from the Web server 40 and returns the search result to the Web server 40.

  The Web server 40 includes a response unit 41 and a template holding unit 42 as a link destination data storage unit. The response unit 41 responds to the search request from the mobile phone 60. The template holding unit 42 holds data of a search page and a page displaying a search result.

  The mobile phone 60 connects to the Web server 40 from the mobile phone communication network 70 via the gateway server and uses a search site made up of the Web server 40. When a user operates the mobile phone 60 to access a search site and inputs a search keyword, the search keyword is transmitted to the response unit 41 of the Web server 40. The search keyword transmitted to the response unit 41 is transmitted to the search unit 32 of the search server 30. The search unit 32 that has received the search keyword searches the database 31 for a URL having a keyword corresponding to the search keyword. Then, the search unit 32 creates a response message including the data of the search result, and transmits this response message to the response unit 41 of the Web server 40. The response unit 41 transmits the search result to the mobile phone 60 using the response page data stored in the template storage unit 42.

  Next, the first feature point of the present embodiment will be described. The specific keyword acquisition link destination data including the acquisition link destination data (URL) corresponding to the specific keyword is created in advance as a display page for the search result of the specific keyword, and the pre-created acquisition link destination data for the specific keyword is generated. The data is stored in the template holding unit 42 as a link destination data storage unit. When a search for a specific keyword is requested, the page address (URL) of the acquisition link destination data for the specific keyword is returned to the response unit 41 without referring to the database 31. Hereinafter, these processes will be described as specific keyword processes.

FIG. 9 is a block diagram showing a configuration of a search system capable of executing specific keyword processing. As shown in FIG. 9, the search server 30 includes a specific keyword holding unit 33. The specific keyword holding unit 33 stores a specific keyword registered in advance by the administrator and a URL of a search result page corresponding to the specific keyword as specific keyword acquisition link destination data created in advance by the administrator. ing. In addition, the search server 30 includes specific keyword determination means 34. The specific keyword determination unit 34 determines whether the search keyword transmitted from the response unit 41 is a specific keyword stored in the specific keyword holding unit 33.
The management server 50 includes a specific keyword processing unit 53 that stores information on a search result page corresponding to the specific keyword holding unit 33 and the specific keyword. The administrator manages information in the specific keyword processing table 53 from the personal computer 100 via the administrator Web function 52. Then, the specific keyword processing table 53 is appropriately changed on the personal computer 100 to update the search result page corresponding to the specific keyword held in the specific keyword holding unit 33 or the specific keyword held in the template holding unit 42. To do.

The search result page corresponding to the specific keyword created by the administrator is created, for example, by browsing the link destination displayed as the search result related to the specific keyword by the administrator. In addition, if the administrator surfs the net and the specific keyword is not used in the content information, but the content is very relevant to the specific keyword, the URL of the content information is put on the search result page. Yes.
The search result page of the specific keyword makes it easy to search for a site of information desired by the user from the search result page by changing the display form for each specific keyword. For example, if the specific keyword is “Ringtone”, the search result page for “Ringtone” is displayed by genre such as “Pop” or “Rock”, or the link destination is recommended. .

  In addition, for example, words having similar meanings such as “PC” and “PC”, “doctor” and “doctor” are registered as specific keywords, and the administrator collects words having the same meaning in a group. A combined result display page may be created in advance. In this way, for example, the same result can be displayed regardless of whether the user inputs “doctor” or “doctor” as a search keyword. As a result, when the desired information cannot be obtained with a certain search keyword or the search result is 0 as in the past, it is necessary to change the search keyword to the same meaning and search again. Can be eliminated.

  When the user inputs a search keyword and executes a search, the response unit 41 transmits the search keyword input by the user to the search unit 32. The search keyword sent to the search unit 32 is checked by the specific keyword determination unit 34 to determine whether or not the search keyword exists in the specific keyword holding unit 33. If it is not in the specific keyword holding unit 33, information corresponding to the search keyword is searched in the database 31, and the search result is sent to the search unit 32. The search unit 32 transmits the search result to the response unit 41, and the response unit 41 transmits the data of the normal search result page stored in the template holding unit 42 to the mobile phone 60. On the other hand, when the specific keyword determination unit 34 matches the specific keyword stored in the specific keyword holding unit 33 with the search keyword, the URL of the search result page corresponding to the specific keyword stored in the specific keyword holding unit 33 is set. The data is sent to the search unit 32. The search unit 32 sends this URL to the response unit 41, and the response unit 41 connects to the URL and displays a search result page corresponding to the specific keyword in advance on the mobile phone 60.

Also, conventionally, when a search was executed without entering anything in the keyword input part of the search page, an error page was displayed, but the search was executed without entering anything in the keyword input part of the search page. If it is, an information page created in advance may be displayed. This information page is, for example, information describing the content destination of information useful for the user obtained by the Internet surfing by the administrator, updated popular site information, and high-level keywords frequently searched by site users. Is displayed.
When a search is executed without inputting anything in the keyword input part of the search page, a NULL value is sent from the response part 41 to the search part 32. The specific keyword holding unit 33 holds a NULL value and a URL corresponding to the NULL value. This URL is an address of an information page created in advance stored in the template holding unit 42. If it is determined that the search keyword sent by the specific keyword determination unit 34 is a NULL value, the URL corresponding to the NULL value held in the specific keyword holding unit 33 is read and sent to the search unit 32. The search unit 32 sends this URL to the response unit 41, and the response unit 41 transmits the information page created in advance by connecting to this URL to the mobile phone 60.

Next, search by pictograms, which is the second feature point of the present embodiment, will be described. FIG. 10 is a diagram showing search pages held in the Web server 40. When the keyword input section 300 of the search page is pulled down, a list of pictograms as shown is displayed. The search server 30 has a pictogram table as pictogram information storage means, and each pictogram is associated with a category assigned as an index. Specifically, for example, a category related to “game” and a category related to “ringtone” are assigned to the index table. In addition, an invader pictogram code in FIG. 10 is stored in the “game” category, and a pictogram code is stored in association with the category in the index table, such as the musical note pictogram shown in FIG. 10 in the “ringtone” category. The retrieved pictogram table is held in the search unit 32.
When the user pulls down and selects and executes one of the pictographs, the response unit 41 of the Web server 40 transmits this pictograph code to the search unit 32 instead of the search keyword. The retrieval unit 32 retrieves a category corresponding to this pictograph code from the pictograph table, and retrieves the same category from the index table of the database 31 using this category as a search keyword. Then, the page address (URL) to which this category is assigned is extracted from the database 31 and a response message is transmitted to the response unit 41 of the Web server 40.

In the above description, the pictogram table is held in the search unit 32. However, the pictogram table may be held in the database 31 together with the index table. Specifically, the category related to “Game”, the category related to “Game” in the index table classified into the category related to “Ringtone”, and the pictogram code of musical notes are assigned to the category related to “Ringtone”, respectively. Keep it. This pictograph code is assigned in association with the category when the index table creating means 21 of the index server 20 adds additional information such as a category to the index table.
When a pictogram search is executed, a corresponding pictogram code is searched from the index table of the database 31, and information to which a category corresponding to the pictogram is assigned is displayed on the mobile phone 60 as a search result.

However, the pictogram code may differ depending on the model of the mobile phone 60. For example, when a pictograph code corresponding to model A is assigned to the index table, a pictograph code of “Invader” may be a pictograph code of “Note” in other models, and a pictograph code of “note” may be used in other models. Then, the result of the user selecting and searching for the pictograph of “note” is not the search result of “ringtone” but the search result of “game”. In addition, depending on the model, there may be a problem that pictograms when pulled down are not displayed correctly.
Therefore, in the present embodiment, the response unit 41 of the Web server 40 obtains model information from the mobile phone 60. As shown in FIG. 11, the response unit 41 includes a table that stores model names and model codes. The template holding unit 42 holds search page data corresponding to each model code. When the response unit 41 obtains the model information from the mobile phone 60, the corresponding model code is obtained from the model information. When the model code is obtained, the search page data corresponding to the model code is read from the template holding unit 42 and transmitted to the mobile phone 60. Thereby, pictograms are correctly displayed on any model.
When the user inputs a pictograph and requests a search, the response unit 41 transmits the model code together with the pictograph code to the search unit 32. The search unit 32 holds a pictograph table including model codes, pictograph codes, and categories as shown in FIG. 12, for example. And the search part 32 grasps | ascertains a category from the model code and pictogram code transmitted from the response part 41, and the table shown in FIG. When the search unit 32 grasps the category, the search unit 32 searches the database 31 for information to which the category is assigned, and transmits the search result to the response unit 41 together with the model code. The response unit 41 reads the response page data corresponding to the model code from the template holding unit 42 and transmits it to the mobile phone 60.

  The specific keyword process, which is the first feature point of the present embodiment, is not limited to characters, and the specific keyword process may be executed for pictograms. In this case, the specific keyword holding unit 33 stores a pictographic code of a note corresponding to “ringtone” and an emoticon code of an invader corresponding to “game”. Further, a search result page corresponding to these pictograms is created and stored in the template holding unit 42. For example, when the user inputs a pictograph of a note and requests a search, the specific keyword determination unit 34 checks whether the specific keyword holding unit 33 has a pictographic code corresponding to the note. When the pictographic code of the note is stored in the specific keyword holding unit 33, the URL of the search result page of “ringtone” corresponding to the pictograph of the note created in advance is sent to the search unit 32. Then, the response unit 41 connects to the URL, and transmits a search result page of “ringtone” created in advance to the mobile phone 60.

(1)
As described above, according to the search system of the present embodiment, the search keyword input by the mobile phone 60 as the information communication terminal is stored in the specific keyword holding unit 33 as the keyword storage unit in which the specific keyword is stored. Whether or not it is a keyword is determined by the specific keyword determining means 34. When the search keyword is determined to be the specific keyword, a search result page relating to the specific keyword created in advance so as to include the URL of the content information as browsing information related to the specific keyword is displayed. Accordingly, content information as browsing information that does not use the specific keyword can be displayed as the search result. As a result, it is possible to reliably obtain information that the user wants to obtain. In addition, the search results can be displayed so that the specific keywords are easy to see, and the convenience of the site can be improved.
(2)
Conventionally, when a search is executed without inputting anything, an error page is returned. For this reason, the user needs to return to the search site again and input the keyword again. However, in the search system according to the present embodiment, when a search is executed without any input by the mobile phone 60, a link destination that is useful information for the user obtained by the administrator through the net surfing is provided. The indicated information page is displayed. In this way, even when a search is executed without inputting anything, the convenience of the site can be improved by displaying information useful for the user.
(3)
In the present embodiment, there is also a pictogram table as pictogram information storage means in which pictogram codes as pictogram information are recorded in association with keywords (categories) in the index table held in the database 31. . When only one pictogram is input to the keyword input unit 300, a search keyword (category) corresponding to the pictogram code input from the pictogram table is specified, and the specified search keyword is searched from the index table of the database 31. As a result, a keyword search result associated with the pictogram can be obtained by inputting only one pictogram. Therefore, a desired search result can be easily obtained as compared with the conventional method of creating a keyword of information desired to be obtained by inputting a plurality of characters into the keyword input unit. In addition, the search can be enjoyable and enjoyable compared to the conventional search using only characters, leading to an increase in the number of accesses.
In addition, if pictograms are pulled down and collectively displayed so that a desired pictogram can be selected from the list display, pictograms can be input to the keyword input section more easily.
(4)
Further, according to the search system of this embodiment, when the user inputs a pictograph and requests a search, the response unit 41 also transmits the model code of the mobile phone 60 together with the pictograph code. The search unit 32 holds a pictographic table including model codes, pictographic codes, and categories. Then, the category is grasped from the pictogram code and the model code transmitted to the search unit 32, content information relating to this category is retrieved from the database and displayed on the mobile phone 60. Thereby, a correct search result can be obtained with any model.
(5)
In addition, according to the mobile phone search system of the present embodiment, the information providing server and the content information are not connected unless the prescribed information is satisfied, and information on these sites is not collected. Thereby, as a result of connecting to the link destination displayed in the search result searched by the user, it is possible to suppress infection with a virus or illegal reading of information. Therefore, the user can use the search site with peace of mind, which can lead to an increase in users.
