  When the data processing unit 360 acquires a login request based on a user instruction from the communication terminal device 10 in conjunction with the recording device 340 under the control of the server management control unit 350, the data processing unit 360 is configured to receive each user's SNS based on the request. The log-in process is performed, and a check-in process for a predetermined facility is performed. Information when each user checks in is registered in the history information DB 344 as history information. Then, the data processing unit 360 executes a group creation process based on a user instruction received via each communication terminal device 10.

  The data processing unit 360 works with the facility information DB 342, the group management DB 343, and the history information DB 344 together with the communication terminal device 10, and when receiving a recommendation information acquisition request, the already registered facility attribute information, group Based on the information and the history information, a process of specifying the preference of the group GR specified by the user via the communication terminal device 10 (hereinafter referred to as “group preference specifying process”) is executed. Then, the data processing unit 360 specifies a facility to be recommended for the specified group GR and distributes the specified facility to the communication terminal device 10 of the corresponding user as recommendation information.

  Note that the execution timing of the group preference specifying process and the recommendation information generation by the data processing unit 360 is arbitrary, and may be executed immediately after the group creation process is completed, or a predetermined period of time elapses after the group creation process. It may be performed later.

  Specifically, the data processing unit 360 executes a DB information management unit 361 that executes a check-in process and a group creation process, and a group preference specifying process by executing an application in order to execute each of the processes described above. A group preference calculation unit 362 to be executed and a recommendation information generation unit 363 that specifies a facility to be recommended and generates recommendation information are realized.

  For example, the DB information management unit 361 of the present embodiment constitutes the first management unit, history information management unit, group information registration unit, and position information acquisition unit of the present invention, and the group preference calculation unit 362 includes the present invention. User specifying means, reading means, extracting means, and determining means. Further, for example, the recommendation information generation unit 363 of this embodiment constitutes a generation unit and a distribution unit of the present invention.

  The DB information management unit 361 acquires position information from the communication terminal apparatus 10 according to the user's check-in instruction transmitted from the communication terminal apparatus 10 and, at the same time, obtains a predetermined distance range from the point corresponding to the position information (for example, 1 km) is specified based on the facility attribute information. Then, the DB information management unit 361 distributes resource data (check-in facility list data) corresponding to the specified facility list to the communication terminal device 10.

  Then, the DB information management unit 361 accepts check-in at the corresponding facility in accordance with the user's instruction received via the communication terminal device 10 based on the check-in facility list data, and the facility checked in by the user The history information including the facility ID, accompanying person ID, and visit date / time is generated, and the history information and the user ID are associated with each other and registered in the history information DB 344.

  Further, the DB information management unit 361 acquires the user belonging to the group GR, the set date and time of the group GR, and the set location position information at that time, while assigning the group ID, based on the instruction from the communication terminal device 10. A group creation process for registering each acquired information as group information in the group management DB 343 is executed. Note that the DB information management unit 361 has a configuration capable of updating and registering users who participate in the group GR after the group creation processing.

  When the group preference calculation unit 362 receives a user's recommendation information acquisition request input via the communication terminal device 10 after completion of the group creation processing, the group preference calculation unit 362 executes the group preference specifying process, and the user of the communication terminal device 10 The facility genre that matches the preference of the entire group GR to which the user belongs is specified. The details of the group preference calculation unit 362 and the group preference identification process of this embodiment will be described later.

  The recommendation information generation unit 363 generates recommendation information for recommending facilities belonging to the facility genre (hereinafter referred to as “specific facility genre”) specified by the group preference calculation unit 362, and performs communication control on the generated recommendation information. The data is distributed to the corresponding communication terminal device 10 via the unit 310. The details of the group preference calculation unit 362 and the group preference identification process of this embodiment will be described later.

  In addition, the recommendation information generation unit 363 extracts a facility included in a predetermined condition from facilities that match the facility genre specified by the group preference calculation unit 362, and specifies the extracted facility as information to be recommended. Then, the recommendation information generation unit 363 generates recommendation information based on the facility attribute information of the specified facility and distributes it to the corresponding communication terminal device 10.

[3.2] Group Preference Calculation Unit Next, the group preference calculation unit 362 and the group preference specifying process in the data processing unit 360 of the present embodiment will be described.

  The group preference calculation unit 362 determines the attribute of the facility that the affiliated user has a high tendency to visit based on the facility attribute information that the affiliated user has visited in the past extracted by the DB information management unit 361. That is, the group preference calculation unit 362 uses the information on the facilities visited by the user belonging to the group GR in the past to determine the attributes of the facilities that the belonging user has a high tendency to visit. The visit frequency for each attribute is calculated based on the user history information, and the attribute of the facility that the affiliated user belonging to the group GR has a high tendency to visit is determined based on the visit frequency.

  In particular, the group preference calculation unit 362 is a facility that any user belonging to the group GR has visited, while it is a facility that is fresh for other users belonging to the group GR and that matches the preference. In order to provide highly reliable information that matches the preference of the affiliated user based on the past history, a group preference specifying process is executed.

  Specifically, the group preference calculation unit 362 allows the user to specify the facility category in accordance with the purpose of creating the group GR to which the user belongs (for example, to eat, drink, or play), while the user specifies the communication terminal device 10. When the recommendation information acquisition request input via the user ID is received, the group information DB 343 is searched based on the user ID of the user, and user IDs corresponding to all the users belonging to each group GR are stored in the ROM / Temporarily record in RAM320.

  Then, for the facility category designated by the user (that is, the designated facility category), the group preference calculation unit 362 calculates, for each belonging user, the number of visits to the facility visited by other belonging users from the history information. For example, when the user belonging to the group GR is “user A” and “user B” is “user C”, “user A”, “user B”, “ The number of visits is calculated by a combination of “user A” and “user C” and “user B” and “user C”.

  It should be noted that the group preference calculation unit 362 uses, as a history, the number of visits to a facility belonging to a designated facility category that has visited another user who does not belong to the group GR, or visited alone, instead of the combination of belonging users. For example, a designated facility that has visited a user who does not belong to the group GR, or has visited alone only at the time of the first group preference specifying process in a user who first joined the group GR, or visited alone The number of visits to facilities belonging to the category may be calculated as a history.

  Then, the group preference calculation unit 362 determines the genre having the largest percentage of the number of visits among the users belonging to the group GR or the genre for which the variance value calculated based on the number of visits satisfies a predetermined condition as the specific facility genre. To do.

  When the genre having the highest percentage of visits among the users belonging to the group GR is set as the specific facility genre, the group preference calculation unit 362 shows a history indicating the number of visits with other belonging users belonging to the group GR. The total number of visits Zj for each facility genre in the entire group GR and the total number Y of visits for all facility genres in the group GR are calculated, and the genre having the highest ratio (= Zj / Y) is selected as the specific facility genre. Determine as.

  In addition, when the specific facility genre is determined using a variance value based on the number of visits for each genre by the user belonging to the group GR, the group preference calculation unit 362 calculates the number of visits for each genre for the user belonging to the group GR. In addition, a variance value for each genre is calculated, and a genre having a variance value satisfying a predetermined condition is determined as a specific facility genre from the calculated variance values.

Specifically, the group preference calculation unit 362 detects the number of visits of each genre of the user belonging to the group GR, calculates the average value E (x) of the visit count X in the entire group GR for each genre, based on equation (1), calculates the variance value Sx ² of each genre. In (Expression 1), (n) represents the number of users belonging to the group, and (j) represents a number assigned to each user.

  Then, the group preference calculation unit 362 determines a genre having a variance value satisfying a predetermined condition from the calculated variance values of each genre as a specific facility genre. In particular, the group preference calculation unit 362 is configured such that the group preference calculation unit 362 has a genre having the lowest variance value or a variance value having a predetermined range (for example, ± 2.0) from the lowest variance value. The genre having the highest average value is determined as the specific facility genre having a predetermined condition.

For example, in the case where the users belonging to the group GR are A, B, C, D, and E. In the “Italian” genre, A is “4 times”, B is “10 times”, and C is “2”. Times, D is “6 times”, E is “0 times”, and in the “French” genre, A is “4 times”, B is “5 times”, C is “3 times”, D is Assume that “4 times” and E have visited “6 times”. In this case, the group preference calculation unit 362 detects the number of visits for each genre, sets the variance Sx ² of the genre “Italian” to “11.84”, and the variance Sx ² of the genre “French” to “1”. .04 ”and“ French ”is determined as the specific facility genre having the lowest variance value.

[3.3] Recommendation Information Generating Unit Next, the group preference calculating unit 362 and the group preference specifying process in the data processing unit 360 of the present embodiment will be described.

  The recommendation information generation unit 363 generates information on a facility that belongs to the facility attribute information having an attribute (that is, the facility genre) that matches the determined specific facility genre and has a predetermined condition as recommendation information.

Specifically, the recommendation information generation unit 363 selects, based on the facility attribute information, from the facilities that match the specific facility genre.
(1) A facility existing within a predetermined distance range (for example, 1 km) from the gathering location of the group GR or the location where the recommendation information distribution request is made,
(2) Facilities that the user belonging to the group GR has not yet visited with other users, and
(3) The highest rated facility or the highly rated facility (for example, the top three) in the evaluation information included in the facility attribute information
A facility having at least one of the above conditions is identified as a facility to be recommended.

  In other words, facilities that should be recommended are facilities that are far from the meeting place of the group GR or the location where the recommendation information is requested to be delivered. Is the same.

  In addition, the facility belongs to the facility attribute information having the facility genre that matches the determined specific facility genre, and the affiliation user belonging to the corresponding group GR has one or more other affiliation users (or all other affiliation users). The information that some of the affiliated users know is safe, while the information that many of the affiliated members already know is not fresh, It cannot be useful information.

  Therefore, the recommendation information generation unit 363 specifies a facility having at least one of the above conditions (1) to (3) as recommendation information in order to provide useful recommendation information.

  In particular, the recommended information generation unit 363 matches the determined specific facility genre when the user belonging to the corresponding group GR specifies a facility that has not yet been visited by another user as a facility to be recommended. The facility belonging to the facility attribute information having the facility genre is compared with the facility that each affiliated user has already visited based on the history information of each affiliated user belonging to the corresponding group GR. Specifically, a facility to which a certain number or more of belonging users have not yet visited among the belonging users belonging to the corresponding group GR is specified as a facility to be recommended.

  Note that the recommendation information generation unit 363 is arbitrary regarding the content and format of the recommendation information. For example, the recommendation information includes a content that causes the communication terminal device 10 to display a list of identified facilities so that the user can view the list. May be generated. Further, the recommendation information generation unit 363 may include evaluation information and other information included as each facility attribute information in the facility list included in the recommendation information.
