- the public range list is a list of public range information including a user ID of a user (registered user) who has assigned a category to a facility and a public range set at the time of granting the category.
- a plurality of users may give a category and a disclosure range to one facility, one or more disclosure range information can be included in the disclosure range list.
- An example of facility information stored in the facility database 11A is shown in FIG.
- the category registration unit 13A is means for receiving input information sent from the portable terminal T and updating the facility database 11A and the category database 14 based on the input information.
- the update method of category information is the same as that of the first embodiment, but the update of facility information is different from that of the first embodiment.
- the category registration unit 13A adds a category name to the category list of the facility information specified by the received facility ID and executes a process for adding the disclosure range information to the disclosure range list of the facility information for the facility database 11A. To do.
- new facility information including information indicating the category name and disclosure range
- the category registration unit 13A gives a new facility ID to the facility information, and the facility information is used as the facility information. Register in the database 11A.
- the search unit 18A is means for extracting facility information corresponding to the location information and category name included in the request signal and satisfying the disclosure range from the facility database 11A. First, the search unit 18A extracts another category name (related category name) associated with the designated category name from the dictionary database 16. Subsequently, the search unit 18A reads from the facility database 11A the facility information of the facility that includes either the designated category name or the related category name and exists within a predetermined range from the position indicated by the input position information. The process so far is the same as the process of the search part 18 in 1st Embodiment.
- the search unit 18A determines whether or not to transmit each facility information read out to the mobile terminal T as a search result. Specifically, the search unit 18A sets the facility information whose specified category name is included in the category list as a transmission target. This is because the user (request user) of the portable terminal T that is the transmission source of the request signal gives a category to the facility information. On the other hand, for the facility information in which only the related category name is included in the category list, that is, the facility information to which the category is given only by the user other than the requesting user (other users), the search unit 18A performs the following processing.
- the search unit 18A does not apply any disclosure restriction to the facility information. Send target.
- the search unit 18A refers to the user relation database 20 and determines the ID of the requesting user. Then, it is determined whether or not there is user relationship information indicating a combination of the other user ID and the disclosure range indicated by the disclosure range information. Then, the search unit 18A sets the facility information to be processed as a transmission target if at least one such user relation information exists, and excludes the facility information from the transmission target otherwise. This means that if the requesting user is permitted to view the facility information by at least one other user, the facility information is to be transmitted.
- the search unit 18A extracts facility information to be provided to the requesting user by the above processing, and outputs it to the result transmission unit 19 as a search result.
- FIGS. 18 is a diagram showing only the facilities corresponding to the facility information of FIG. 17 among the facilities shown in FIG.
- the search unit 18A not only has “cafe” added to three stores (stores a to c) to which “cafe” is assigned. 4 stores (stores d to g) to which the related category name “tea” or “study place” is assigned.
- the search unit 18A targets these three stores for transmission. Since only “no restriction” is set in the disclosure range list of the store d, the search unit 18A also sets the store d as a transmission target. In the store e, the public range is set as “friends only” by the user B, but the users A and B are set as friends, so the search unit 18A also sets the store e as a transmission target. On the other hand, since the disclosure range is set as “company voluntary” by the user C in the stores f and g, and the users A and C are not set as the company volunteers, the search unit 18A selects the store f. , G are excluded from transmission targets. Accordingly, the search unit 18A outputs only the facility information of the stores a to e to the result transmission unit 19.
- the search unit 18A can output the search result as follows.
- the search unit 18A may compare the registered user information with the user relationship information, and set the display order on the screen De for each extracted facility information.
- the search unit 18A displays the facility information in which a person who has a predetermined relationship with the requesting user on the user relationship information is a registered user so that the facility information is displayed higher than the facility information with no restriction on the disclosure range.
- the display order may be set.
- the search unit 18A may extract only facility information in which a person who has a predetermined relationship with the requesting user is a registered user on the user relationship information.
- the request signal further includes user range information indicating a search range based on the user relationship (for example, user range information indicating that “facility registered by a friend is searched”).
- the search unit 18A compares the user range information, the user relationship information, and the facility information extracted as described above, and outputs only the facility information existing within the search range indicated by the user range information as a search result.
- the structure of a search program P1A for causing a computer to function as the search server 10A is as shown in FIG.
- the search program P1A includes a facility storage module P11A, a category registration module P13A, and a search module P18A instead of the facility storage module P11, the category registration module P13, and the search module P18 in the first embodiment.
- the search program P1A also includes a user relationship storage module P20.
- the functions realized by executing the facility storage module P11A, the category registration module P13A, the search module P18A, and the user relationship storage module P20 are the facility database 11A, the category registration unit 13A, the search unit 18A, and the user relationship, respectively.
- the function is the same as that of the database 20.
- this embodiment can achieve the same effects as those of the first embodiment. Furthermore, in the present embodiment, facility information is extracted in consideration of whether or not information is disclosed based on the relationship between users as well as whether or not the category name matches. Therefore, it is possible to provide the user with a search result reflecting the connection (intimacy) between the users.
- the dictionary registration unit 15 creates a dictionary related to the category name, but the words and phrases placed in the dictionary data are not limited in any way. Further, the purpose of use of the created dictionary is not limited to facility search, and the present invention can also be applied to creation of a dictionary used for searching for other types of information.
- the search servers 10 and 10A include various databases.
- a server other than the search server includes a database, and the search server accesses the database via a communication network to acquire information.
- the search server may not include a database corresponding to the user relationship database 20, and may acquire user relationship information from a user relationship database provided in a predetermined SNS server.
- the search server may acquire facility information from a facility database provided in a predetermined facility management server without providing a database corresponding to the facility databases 11 and 11A.
- the position information included in the category information is expressed in the form of latitude and longitude, but the expression format of the position information is not limited to this.
- the position information may be indicated in a format other than latitude and longitude (for example, a location).
- the position information may be expressed three-dimensionally by latitude and longitude and altitude.
- category information including position information indicated by (x11, y11, z11) is accumulated in the category database 14.
- the geographical range that the dictionary registration unit 15 regards as a common position is also expressed in a three-dimensional shape.
- the dictionary registration unit 15 sets a range indicated by a virtual cylinder having a radius of several tens of meters and a height of several meters as a geographical range that is regarded as a common position. If position information expressed three-dimensionally is used, it is possible to appropriately determine the overlap of positions to which words are given in consideration of not only the planar range but also the height. For example, more detailed dictionary data can be generated by distinguishing category information corresponding to different floors in the same building.

Abstract
Description
図1~10を用いて、第1実施形態に係る検索サーバ10の機能及び構成を説明する。検索サーバ10は、ユーザが所有する携帯端末Tからの要求に応じて、施設に関する情報(施設情報)をその端末Tに送信するコンピュータ・システムである。なお、施設の例としては店や宿、観光地、公共施設などが挙げられるが、施設の種類はこれらに限定されない。携帯端末Tでは、受信した施設情報を施設のカテゴリ毎に集約して表示するが、このカテゴリはユーザ自身により予め付与されている。検索サーバ10は、施設情報を要求するユーザにより付与されたカテゴリに合致する施設情報だけでなく、そのカテゴリに関連する他のカテゴリに合致する施設情報も携帯端末Tに送信する。このために、検索サーバ10はカテゴリ間の関連が定義された辞書(関連語辞書)のデータベース(後述する辞書データベース16)を備えているが、この辞書は携帯端末Tから送られてくる情報を用いて生成される。
次に、図14~18を用いて、第2実施形態に係る検索サーバ10Aについて説明する。第2実施形態は、ユーザ間のつながり(親密度)を考慮して施設情報が提供されるという点で第1実施形態と異なる。
