Description

[Technical field]

[0001] The present invention relates to an information processing device, an information processing method, and an information processing program. [Background technology]

[0002] There are services that present destinations to users in order to improve mobility in a given area. Furthermore, Patent Literature 1 discloses a method for determining destinations to be presented to a user based on the user's preferences. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-164716 A Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, a category of search targets is determined, the preferences of the user are estimated from posts by the user on SNS (Social Network Service) or the like, and information on facilities such as stores that match the preferences is extracted and presented to the user. However, when facilities such as stores that match the user's preferences are presented as in Patent Document 1, the facilities are facilities that belong to the same category as facilities such as stores that the user has visited in the past. In addition, when a user visits a specific area for the purpose of dining or shopping with acquaintances, the destinations to be visited are often roughly determined. Therefore, the destinations of the user are fixed, and the user is less likely to find new destinations in the area. This reduces the number of users wandering around the area, lowering the attractiveness of the area felt by each user, and does not lead to an improvement in the attractiveness of the area.

[0005] Therefore, the disclosed configuration aims to provide a technology that improves a user's mobility in a specified area. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention employs the following solutions. That is, the first aspect is an information processing device that calculates the similarity between a target user and other users other than the target user using at least one of age, gender, category of facilities of interest, and coupon acquisition history. Furthermore, the information processing device extracts facilities with visit history or coupon acquisition history of other users whose similarity is equal to or greater than a threshold as candidates for facilities to be recommended to the target user. Furthermore, the information processing device selects a facility to be recommended from the extracted candidates using the visit history of the target user as an evaluation item.

[0007] The disclosed aspects may be realized by a program being executed by an information processing device. That is, the disclosed configuration may be specified as a program for causing an information processing device to execute the processes executed by each of the means in the above-mentioned aspects, or a computer-readable recording medium on which the program is recorded. The disclosed configuration may also be specified by a method in which an information processing device executes the processes executed by each of the above-mentioned means. The disclosed configuration may also be specified as a system including an information processing device that executes the processes executed by each of the above-mentioned means. Effect of the Invention

[0008] According to the present invention, a technology is provided that can improve a user's mobility in a given area by recommending facilities that the user is not aware of using information about similar users. Cut. [Brief description of the drawings]

[0028] The memory 92 includes, for example, a random access memory (RAM) and a read only memory (ROM). The memory 92 is also called a main storage device.

[0029] The storage unit 93 is, for example, an EPROM (Erasable Programmable ROM) or a hard disk. The storage unit 93 is a removable media. The removable media may include, for example, a Universal Serial Bus (USB) memory or a disk recording medium such as a Compact Disc (CD) or a Digital Versatile Disc (DVD).

[0036] (Example of operation) 5 is a diagram showing an example of an operation flow of the server device 100 of this embodiment. Here, it is assumed that a predetermined application is pre-installed in the terminal device 200 carried by the user. The application is an application that provides information on facilities such as stores in a predetermined area to a user staying in the predetermined area (the terminal device 200 present in the predetermined area). Hereinafter, the application is also referred to as an area application.

[0037] When an area application is started in the terminal device 200 carried by a user (target user), the control unit 202 of the terminal device 200 detects the position of the terminal device 200 via the position detection unit 212. The position of the terminal device 200 corresponds to the position where the user carrying the terminal device 200 is present (stays). The control unit 202 determines whether the detected position is within a predetermined area. If the detected position is within the predetermined area, the control unit 202 transmits position information of the detected position together with the identification information of the user to the server device 100 via the communication IF 206. When the server device 100 receives the position information etc., the operation flow of FIG. 5 is started.

[0038] The determination of whether the detected position is within a predetermined area may be performed by the server device 100. In this case, the control unit 202 of the terminal device 200 transmits position information of the detected position together with the identification information of the user to the server device 100 via the communication IF 206. In this case, the control unit 202 of the terminal device 200 transmits the detected position information, etc. to the server device 100 at predetermined time intervals. When the control unit 102 of the server device 100 receives the position information, etc. via the communication IF 106, it determines whether the position indicated by the position information is within a predetermined area. If the position is within the predetermined area, the operation flow of FIG. 5 is started.

[0039] In S101, the control unit 102 of the server device 100 stores the location information of the terminal device 200 and the user's identification information transmitted from the terminal device 200 in the storage unit 104. The control unit 102 calculates the similarity between the user and another user. The user and the other user are users who use the area application. The similarity is an index that indicates the similarity of the preferences of two users. For example, cosine similarity is used for the similarity. The cosine similarity takes values ​​from -1 to +1, and the closer the value is to +1, the higher the similarity is. The storage unit 104 stores information about each user in a digitized form in advance. That is, the storage unit 104 stores information about a plurality of users in a digitized form in advance. The plurality of users includes the target user and other users other than the target user.

[0040] FIG. 6 is an example of information about a user stored in the storage unit 104. In the example of FIG. 6, for each user, a user ID (user identification information), age, sex, categories of interest, coupon acquisition history, and location information of the area of ​​stay are quantified and stored. Here, the user ID is identification information for identifying each user. Age is quantified for each generation. For example, age is 0 for teens, 1 for twenties, 2 for thirties, 3 for forties, 4 for fifties, and 5 for ages sixty or older. Gender is 0 for men and 1 for women. Part of the categories of interest is a category of facilities of interest. The category of facilities of interest may be used instead of the categories of interest.

[0041] The categories of interest are quantified for each category, such as cafes, bars, and clothing. Here, categories in which the user is interested are quantified as 1, and categories in which the user is not interested are quantified as 0. For example, in the example in Figure 6, for user ID "A", "cafes" is quantified as 0. "Cafes" and "clothing" are 1, and "taverns" are 0. This indicates that a user with user ID "A" is interested in "cafes" and "clothing", but not in "taverns". "Cafes" and "taverns" are examples of categories of facilities of interest.

[0042] The coupon acquisition history (coupon acquisition history) is a history of coupons acquired in the past. Acquired coupons are assigned a value of 1, and unacquired coupons are assigned a value of 0. For example, in the example of FIG. 6, for user ID "A", "coupon A" is assigned a value of 1, and "coupon B" is assigned a value of 0. This indicates that a user with user ID "A" has acquired "coupon A" but has not acquired "coupon B". Coupons are discount coupons, vouchers, service coupons, etc. that can be used at stores and other facilities in the area. Coupons are intended to encourage users to visit stores and other facilities. Each coupon is associated with a store or other facility where the coupon can be used.

[0043] The location information of the stay area is latitude and longitude information indicating the location of the area where the user stays. The location information of the stay area may be latitude and longitude information of the location where the user stays. The location information of the stay area may be latitude and longitude information indicating the location of an area where the user frequently stays. The location information may be indicated by information other than latitude and longitude information.

[0044] The information about the user may include information about the user's visit history (whether or not the user has visited a store, etc.).

[0045] The information about the user is acquired, for example, when the area application is first launched, by the terminal device 200 conducting a questionnaire for the user and analyzing the questionnaire. The terminal device 200 transmits the questionnaire results to the server device 100. The server device 100 digitizes the information about the user based on the questionnaire results, etc. (e.g., FIG. 6) and stores the information in the memory unit 104 for each user. The server device 100 acquires coupon acquisition history from the terminal device 200 or other information processing devices, digitizes the history, and stores the history in the memory unit 104 for each user. The memory unit 104 stores information about each user, including information about facilities related to each user, for multiple users.

[0046] The control unit 102 calculates the similarity between the user and all other users. For example, the control unit 102 calculates the similarity by the following formula.

number

[0047] The similarity is a cosine similarity. The similarity indicates the similarity between the user and the i-th other user. Here, the vector a is a vectorization of information about the user. Each element of the vector a is, for example, a numerical representation of the age, sex, category of interest (cafe, tavern, clothing, etc.), and coupon acquisition history (coupon A, coupon B, etc.) in FIG. 6. The vector bi is a vectorization of information about the i-th other user. Each element of the vector bi is, for example, a numerical representation of the age, sex, category of interest (cafe, tavern, clothing, etc.), and coupon acquisition history (coupon A, coupon B, etc.) in FIG. 6. The control unit 102 stores the calculated similarity in the storage unit 104. The similarity is an example of the similarity between the target user and other users. At least one of the age, sex, category of interest, and coupon acquisition history is used to calculate the similarity. The vector a and the vector bi are examples of vectorized information.

[0048] In S102, the control unit 102 extracts similarities equal to or greater than a threshold from among those stored in the storage unit 104. That is, the control unit 102 extracts those with high similarities. The threshold is, for example, 0.95. The threshold may be arbitrarily set in advance by the server device 100 or the terminal device 200. The control unit 102 extracts other users corresponding to the extracted similarities as other users with high similarity to the user. The control unit 102 may also extract other users with the highest similarity to the user as other users with high similarity to the user.

[0049] In S103, the control unit 102 extracts candidates for facilities such as stores to be provided to the terminal device 200. For the other users extracted in S102, the control unit 102 extracts facilities such as stores associated with coupons acquired by the other users. That is, the control unit 102 extracts facilities with coupon acquisition history for the other users. Also, the control unit 102 extracts facilities such as stores that the other users have visited for the other users extracted in S102. That is, the control unit 102 extracts facilities with visit history for the other users. Facilities such as stores associated with coupons acquired by the other users and facilities such as stores that the other users have visited are also referred to as facilities related to the other users. Furthermore, the control unit 102 extracts facilities such as stores associated with coupons acquired by the user for the user. Also, the control unit 102 extracts facilities such as stores that the user has visited for the user. Facilities such as stores associated with coupons acquired by the user and facilities such as stores that the user has visited are also referred to as facilities related to the user. Here, the control unit 102 excludes the facilities extracted for the user from the facilities extracted for the other users. That is, the control unit 102 excludes the facilities associated with the coupons acquired by the user and the facilities that the user has visited from the facilities extracted for the other users. The remaining facilities are facilities extracted for the other users and are facilities with which the user has no relationship. That is, the remaining facilities are facilities that are considered to be unexperienced by the user. In addition, the remaining facilities are facilities associated with coupons acquired by other users who have a high similarity to the user and have been visited, so that the user is expected to be of high interest to the user. That is, the control unit 102 selects a facility to be recommended from the extracted facilities related to the other user (extracted candidates for facilities to be recommended to the user) using the visit history of the user as an evaluation item. The remaining facilities are candidates for facilities such as stores to be provided to the terminal device 200. The control unit 102 stores the candidates for facilities such as stores to be provided to the terminal device 200 in the storage unit 104.

[0050] In S104, the control unit 102 calculates a score indicating the degree to which each of the candidate facilities such as stores provided to the terminal device 200, stored in the storage unit 104, is recommended to the user. The score is calculated based on information about each facility and information about the user. A higher score indicates a higher degree of recommendation to the user (more recommended). The control unit 102 calculates the score based on the following formula, for example.

number

[0051] Here, U indicates the user. Listi(U) indicates the score for the i-th candidate. itemn indicates the coefficient of the n-th evaluation item. biasn(U) indicates the bias value of the user for the n-th evaluation item. Here, N indicates the number of items used to calculate the score. Here, the evaluation items include, for example, ease of access, environmental contribution, how crowded it is, ease of entering alone, etc. The coefficients and bias values ​​of the evaluation items are determined based on the user's The results of a survey, etc. may be reflected.

[0052] The ease of access is an item indicating the ease of access to the candidate (ease of access to the facility). For example, the coefficient of ease of access is 10-distance from the user's current location to the candidate [m] / 200 [m]. Also, for example, the bias value of ease of access is whether or not the user has passed in front of the candidate (for example, 1 if yes, 0 if no). Also, the bias value of ease of access may be set to be lower as the user is older.

[0053] The environmental contribution is an item that indicates the environmental load (environmental contribution due to travel) when traveling to the candidate. For example, the coefficient of the environmental contribution is 10-CO2 emissions per unit travel distance [g / km] x (distance from the user's current location to the candidate) [m]. For example, the bias value of the environmental contribution is a value according to the level of environmental awareness of the user. In this case, the higher the environmental awareness of the user, the higher the bias value of the environmental contribution.

[0054] The congestion level is an item that indicates the congestion level (crowding situation) at the candidate. For example, the congestion level coefficient is 10-number of people staying at the candidate / capacity of the candidate. The congestion level coefficient is lower the more crowded the facility is. The bias value of the congestion level is higher the more the user dislikes crowdedness.

[0055] The ease of entering alone is an item that indicates the ease of entering the candidate alone (ease of going alone). For example, the coefficient of ease of entering alone is 10 x number of counter seats / (number of counter seats + number of table seats). For example, the bias value of ease of entering alone becomes higher the more the user prefers being alone.

[0056] The evaluation items may include other items (such as whether or not there is a time-limited event, the travel load due to the presence or absence of luggage, etc.). The numerical values ​​used in calculating the score may be stored in advance in the storage unit 104, or may be acquired from another information processing device or the terminal device 200, etc. The evaluation items include one or more of the following: ease of access to the facility, contribution to the environment by travel, congestion, ease of access alone, whether or not there is a time-limited event, and the travel load due to the presence or absence of luggage.

[0057] The control unit 102 stores the calculated score for each candidate in the storage unit 104.

[0058] In S105, the control unit 102 extracts information on the candidate facilities with the highest scores calculated in S104 from the storage unit 104 as information on the facilities to be recommended. The control unit 102 extracts information on the candidate facilities with the scores up to the third highest, for example. The number to be extracted may be set in advance by the user in an area application executed on the terminal device 200. At this time, the terminal device 200 transmits the number to be extracted in advance to the server device 100. The server device 100 extracts information on the candidate facilities with the highest scores based on the number to be extracted. The control unit 102 transmits the extracted information on the candidate facilities with the highest scores to the terminal device 200 via the communication IF 106. The extracted information on the candidate facilities with the highest scores includes, for example, information on the location of the facility, the opening time and closing time of the facility, and coupons that can be used at the facility. The control unit 102 may also extract information on the candidate facilities with the scores equal to or higher than a threshold value. The control unit 102 may transmit the extracted scores to the terminal device 200 via the communication IF 106. The control unit 102 may rank the recommended facilities in descending order of scores based on the extracted scores, and transmit information about the recommended facilities together with the ranked scores to the terminal device 200 via the communication IF 106.

[0059] The control unit 202 of the terminal device 200 receives the facility information via the communication IF 206. The control unit 202 of the terminal device 200 controls the display of the output unit 210 based on the received facility information. The display shows information about the facility. The information about the facility to be displayed may include, for example, a map showing the route to the facility, the opening and closing times of the facility, and coupons that can be used at the facility. The user of the terminal device 200 can visit the facility by looking at the display. The facility is a facility that the user has not visited, but is visited by other users similar to the user. Therefore, the user is likely to be interested in the facility. The control unit 202 of the terminal device 200 may display the received information about the facility together with the ranking and score of the facility. The user can recognize the degree of recommendation for the facility based on the ranking and score.

[0060] The operations performed by the server device 100 described above may be performed by the terminal device 200.

[0061] (Actions and Effects of the Embodiments) The server device 100 of this embodiment calculates the similarity between the target user and other users based on information about the user. The server device 100 extracts other users who are highly similar to the target user. The server device 100 extracts facilities related to the other users who are highly similar. The server device 100 also extracts facilities related to the target user. The server device 100 extracts the remaining facilities, excluding the facilities related to the target user, from the facilities related to the other users as candidates for facilities to be provided to the target user. The server device 100 calculates a score indicating the degree to which the extracted candidates are recommended to the target user. The server device 100 transmits information about the candidate facilities with the highest calculated scores to the terminal device 200. The terminal device 200 displays information about the facilities based on the received information. The user of the terminal device 200 can visit the facilities by looking at the display. As a result, the server device 100 can provide the target user with information about the facilities that it would like to recommend to the target user, and can induce the user to visit the facilities. Furthermore, when calculating the scores of the extracted candidates, the server device 100 can recommend facilities that are closer to the user's preferences by taking into account the target user's information. Furthermore, the server device 100 can lower the hurdle for the user to visit the recommended facility by providing the user with information related to the facility (such as location information and coupons). Furthermore, the server device 100 can recommend a facility that the user has not visited (a facility that is not included in the facilities related to the user) to suppress the user from becoming fixed in the destinations to be visited, and can improve the user's mobility in a specified area.
