  The companion input field CAN and the importance input field CAL form a pair, and the search condition screen W1 includes a plurality of pairs of companion input fields CAN and importance input fields CAL. The accompanying person input field CAN is an input field for inputting the name or identifier of the accompanying person. The companion input field CAN may be configured to be selectable from a list displayed in advance based on the participant table 141. The importance level input field CAL is an input field for inputting the importance level of the accompanying person specified in the accompanying person input field CAN. The importance is a value indicating a ratio of emphasizing the person in the recommended facility search process. The higher the importance, the more the facility suitable for the person is searched in the recommended facility search process. In this embodiment, when there are a plurality of companions, the importance is input so that the importance of each companion is added to be 100 (%).

  The date and time input field DT is an input field for inputting the date and time when the facility is scheduled to be used. The date / time input field DT can be omitted. The place input field AR is an input field for inputting an area (region) to be searched for facilities. The purpose input field AM is an input field for inputting the purpose of visiting the facility. The purpose input field is preferably a selection method as shown in FIG.

  The user of the portable terminal 20 inputs in each field of the search condition screen W1, and presses the search button B12. When the search button B12 is pressed, the main control unit 241 of the mobile terminal 20 transmits a request for starting recommended facility search processing to the server 10. Note that the recommended facility search processing start request is input to each field (accompaniment input field CAN, importance input field CAL, date / time input field DT, place input field AR, purpose input field AM) of the search condition screen W1. Contents are included as “search conditions”.

  FIG. 5 is a flowchart showing a procedure of recommended facility search processing. FIG. 6 is an explanatory diagram illustrating a state in which the server 10 searches for a recommended facility through a recommended facility search process. The recommended facility search process is triggered by the server 10 receiving a request for starting the recommended facility search process from the mobile terminal 20.

  In step S102 of FIG. 5, the request acquisition unit 112 of the server 10 acquires a search condition included in the recommended facility search processing start request. Specifically, the request acquisition unit 112 includes the contents of the companion input field CAN and the importance level input field CAL (hereinafter also referred to as “accompanying person condition”) included in the request for starting the recommended facility search process, and the date / time input field. The contents of the DT (hereinafter also referred to as “date and time conditions”), the contents of the location input field AR (hereinafter also referred to as “location conditions”), and the contents of the purpose input field AM (hereinafter also referred to as “target conditions”). get.

  The search unit 113 of the server 10 extracts a facility from the facility table 142 based on the place condition and the purpose condition (step S104). Specifically, the search unit 113 includes the address of the facility table 142 in the area (region) specified by the place condition, and the category of the facility table 142 is related to the purpose specified by the purpose condition. Extract entries. Here, “included” means to allow even when the address of the facility and the address specified by the location condition partially match.

  FIG. 6A shows an example of a facility extracted from the place condition and the target condition. When the place condition is “around Shibuya” and the purpose condition is “entertainment (meal)”, the search unit 113 includes “Shibuya” in the address from the facility table 142 and indicates the category of the restaurant in the category. A facility including a character string is extracted (FIG. 6A).

In step S106 of FIG. 5, the search unit 113 performs filtering using the minus characteristics of the user and the accompanying person. Specifically, the search unit 113 performs the following processing.
(A) The search unit 113 refers to the negative characteristics of the user himself / herself and the negative characteristics of the accompanying person specified by the accompanying person condition from the participant table 141.
(B) The search unit 113 compares the facility characteristics with all the negative characteristics referred to in (a) for the facilities extracted in step S104, and excludes matching or related facilities.

  FIG. 6B shows an example of the negative characteristics of the user and the accompanying person. As shown in the figure, the negative characteristics of Mr. A (user) are “eel”, “shrimp”, and the negative characteristics of Mr. B (accompanied person) are “spicy”, “hot pot”, and Mr. C (accompanied person). Negative characteristics are “cucumber”, “cheese” and “swimming”. In this case, the facility with the facility identifier S006 is excluded from the candidates due to the negative characteristic “eel” of Mr. A. Similarly, facilities with facility identifiers SS011 and S013 are excluded from candidates due to Mr. B's negative characteristic “spicy”. The facility with the facility identifier S010 is excluded from the candidates due to Mr. B's negative characteristic “nabe cuisine”. The facility with the facility identifier S001 is excluded from the candidates due to Mr. C's minus characteristic “cheese”.

  In step S108 of FIG. 5, the search unit 113 performs filtering using the target condition. Specifically, for the facilities extracted in step S106, the search unit 113 excludes facilities whose category or facility characteristics are estimated to be inappropriate from the target conditions. “Category or facility characteristics are not suitable from the target conditions” means, for example, a fast food restaurant or family restaurant or general leisure facility when the target condition is entertainment, or a fast food restaurant or family when the target condition is a date. Examples include restaurants, French restaurants and fitness clubs when the purpose is family service.

  FIG. 6C shows an example of the objective condition. As shown in the figure, when the objective condition is “entertainment (meal)”, the facility with the facility identifier S005 whose facility characteristics are inexpensive is excluded from the candidates. Similarly, facilities with facility identifiers S008 and S015 whose category is fast food are excluded from candidates.

  As in step S108, the search unit 113 extracts a facility in consideration of the purpose of the user to use the facility by filtering using the purpose condition. Therefore, the navigation system 100 provides guidance according to the purpose of using the facility. Information can be provided.

  In step S110 of FIG. 5, the search unit 113 determines the importance of the participant. Note that “participant” means each person who belongs to a group including a user and a companion. The importance of the participant is determined according to the contents of the importance input field CAL of the companion condition and the purpose condition. Specifically, the search unit 113, for example, when the purpose condition is a purpose that the user should focus on “hospitable” (for example, entertainment, family service, etc.), the importance of the user himself / herself among the participants Is 0%, and the content of the companion condition importance input field CAL is used as the companion importance as it is. On the other hand, for example, when the purpose condition is a purpose that the user himself / herself should also enjoy (for example, dating or a meal with a friend), the search unit 113 includes the content of the companion condition importance input field CAL. The importance of each participant is calculated anew, taking into account the importance of. At this time, the importance level of the user himself / herself may be acquired from the user of the mobile terminal 20 or may be automatically set according to the objective condition. In step S110, the search unit 113 also operates as an “importance level determination unit” in the claims. In other steps, the search unit 113 operates as a “search unit” in claims.

  In the example of FIG. 6C, since the objective condition is “entertainment (meal)”, the importance of Mr. A (the user) among the participants is 0%. Further, the importance level of Mr. B input in the importance level input column CAL of the search condition screen W1 (FIG. 4) is 70%, and the importance level of Mr. C is 30%. In this case, the importance of Mr. A is determined to be 0%, the importance of Mr. B is determined to be 70%, and the importance of Mr. C is determined to be 30%.

In step S112 in FIG. 5, the search unit 113 obtains the degree of coincidence with the facility for each participant. Specifically, the search unit 113 performs the following processing.
(A) The search unit 113 refers to the plus characteristic of the user himself / herself and the plus characteristic of the accompanying person specified in the accompanying person condition from the participant table 141.
(B) For each facility extracted in step S108, the search unit 113 compares the category and facility characteristics with all the plus characteristics referred to in (A) to obtain a degree of coincidence.

  Various methods can be employed for obtaining the degree of coincidence. For example, if the category and facility characteristics of a facility match multiple positive characteristics of one participant (user or companion), the number of matching positive characteristics matches that person for that facility. You may appreciate the degree. Further, for example, a preference level (a value indicating the strength of preference) is assigned in advance to the plus characteristic of the participant table 141. Then, according to the preference degree assigned to the plus characteristic that matches the category and the facility characteristic of a certain facility, the degree of coincidence of the facility with respect to the person may be highly evaluated. Further, for example, the above two methods may be combined.

In step S114 of FIG. 5, the search unit 113 calculates the degree of coincidence for the facility as a whole group in consideration of the importance of each participant. Specifically, the search unit 113 performs the following calculation for each facility extracted in step S108.
Group coincidence = (the degree of coincidence of the user determined in step S112 × the importance of the user determined in step S110) + (the degree of coincidence of the first companion obtained in step S112 × determined in step S110) Importance of the first accompanying person) +... + (The degree of coincidence of the nth accompanying person determined in step S112 × the importance of the nth accompanying person determined in step S110)
Note that the degree of coincidence obtained in step S114 corresponds to the “group coincidence” in the claims.

  FIG. 7 shows a state where the server 10 obtains the group matching degree by the recommended facility search process. In FIG. 7, the facility name and address are not shown for the facilities extracted from the facility table 142.
