When acquiring the recommendation information, the processing unit 15 transmits (uploads) the context to a recommendation server that is another server device via the network, and receives the recommendation information corresponding to the context from the recommendation server via the network ( Acquisition). In this case, the recommendation server stores a typical behavior pattern of the user for each user of the mobile terminal 1 as a table, and a recommendation engine describing a rule for performing the recommendation stores the typical behavior pattern. Refer to the table and make a recommendation. For example, when there is “a user of the mobile terminal 1b often goes to drink after 18:00 on a work day” as a typical behavior pattern, the recommendation engine gives a user a work day of 16 to the user of the mobile terminal 1b. Make recommendations at the bar around the time.

  The processing unit 15 may return the processing result based on the context to the application installed in the mobile terminal 1 or may transmit the processing result to another server device via a network. The timing at which the processing unit 15 performs processing may be when the context is estimated by the context estimation unit 14, when the position information of the mobile terminal 1 is changed, or when a nearby terminal appears. It may be regular or when an instruction is given from an application installed in the mobile terminal 1.

The terminal information reception unit 21 outputs the received sensor data to the attribute estimation unit 23. The terminal information receiving unit 21 may store the received sensor data in a database (not shown) in the user attribute estimation device 2.

  The extraction unit 22 extracts from the attribute information storage unit 20 the attribute information of the user of the portable terminal 1a that is the proximity terminal indicated by the proximity terminal information received (input) by the terminal information reception unit 21. The extraction unit 22 outputs the extracted attribute information of the user of the mobile terminal 1 a to the attribute estimation unit 23.

  For example, when the identification information of the portable terminal 1a is input as the proximity terminal information, the extraction unit 22 stores the identification information of the portable terminal 1 and the attribute information of the user of the portable terminal 1 in association with each other. 20, user attribute information stored in association with the input identification information of the mobile terminal 1 a is extracted. For example, when the identification information of the portable terminal 1a is input as the proximity terminal information, the extraction unit 22 stores the identification information of the portable terminal 1 and the identification of the user of the portable terminal 1 stored in the user attribute estimation device 2 in advance. The identification information of the user of the portable terminal 1a associated with the input identification information of the portable terminal 1a is acquired from the table information associated with the information, and the user identification information and the attribute information of the user are stored in association with each other. The attribute information of the user of the portable terminal 1a stored in association with the acquired identification information of the user of the portable terminal 1a may be extracted from the attribute information storage unit 20 thus obtained.

  Further, for example, when the identification information of the user of the portable terminal 1a is input as the proximity terminal information, the extraction unit 22 receives the attribute information storage unit 20 in which the user identification information and the attribute information of the user are stored in association with each other. You may extract the attribute information of the user of the portable terminal 1a stored in association with the input identification information of the user of the portable terminal 1a. Further, for example, when the identification information of the user of the portable terminal 1 a is input as the proximity terminal information, the extraction unit 22 stores the identification information of the user of the portable terminal 1 stored in the user attribute estimation device 2 in advance and the portable terminal 1. The identification information of the portable terminal 1a associated with the input identification information of the user of the portable terminal 1a is acquired from the table information associated with the identification information of the portable terminal 1a, and the identification information of the portable terminal 1 and the user of the portable terminal 1 are acquired. The attribute information of the user stored in association with the acquired identification information of the mobile terminal 1a may be extracted from the attribute information storage unit 20 that is stored in association with the attribute information.

  The attribute estimation unit 23 obtains the attribute information of the user of the portable terminal 1b indicated by the own terminal information received (input) by the terminal information receiving unit 21, and the attribute information of the user of the portable terminal 1a that is the proximity terminal extracted by the extraction unit 22 Estimate based on the attribute information and store it in the attribute information storage unit 20. The attribute estimation unit 23 outputs the estimated attribute information of the user of the mobile terminal 1 a to the attribute information transmission unit 24.

  Specifically, the attribute estimation unit 23 first identifies the user of the mobile terminal 1b based on the own terminal information input from the terminal information receiving unit 21. For example, when the identification information of the portable terminal 1b is input as the own terminal information, the attribute estimation unit 23 stores the identification information of the portable terminal 1 and the identification of the user of the portable terminal 1 stored in the user attribute estimation device 2 in advance. The identification information of the user of the portable terminal 1b associated with the input identification information of the portable terminal 1b is acquired from the table information associated with the information, and the user of the portable terminal 1b is specified based on the acquired identification information. . For example, when the identification information of the user of the portable terminal 1b is input as the self-terminal information, the attribute estimation unit 23 specifies the user of the portable terminal 1b based on the identification information.

  Next, the attribute estimation unit 23 estimates the specified attribute information of the user of the mobile terminal 1b based on the attribute information of the user of the mobile terminal 1a extracted by the extraction unit 22. For example, the attribute estimation unit 23 may estimate the specified attribute information of the user of the mobile terminal 1b as the attribute information of the user of the mobile terminal 1a. That is, the attribute estimation unit 23 uses the specified attribute information of the user of the mobile terminal 1b (for example, location information of the user of the user of the mobile terminal 1b) as attribute information of the user of the mobile terminal 1a (for example, the user of the mobile terminal 1a). It may be estimated that the location information of the home is.

  The attribute estimation unit 23 estimates the attribute information of the user of the portable terminal 1b based on the relationship information (friendship profile) between the user and the user of the portable terminal 1b included in the attribute information of the user of the portable terminal 1a. Also good. Moreover, the attribute estimation part 23 may estimate the positional information contained in the attribute information of the user of the portable terminal 1b based on the positional information contained in the attribute information of the user of the portable terminal 1a.

  For example, when the relationship information between the user and the user of the mobile terminal 1b included in the attribute information of the user of the mobile terminal 1a is “family”, the attribute estimation unit 23 is the attribute information of the user of the mobile terminal 1b. The “home location information” is estimated to be the same as the “home location information” that is the user's attribute information of the mobile terminal 1a, and the “friendship relationship” that is the user's attribute information of the mobile terminal 1b is the “mobile terminal 1a”. "Family place" is estimated to be the same as "Frequently visited place" which is the attribute information of the user of the portable terminal 1a. For example, when the relationship information between the user and the user of the mobile terminal 1b included in the attribute information of the user of the mobile terminal 1a is “colleague”, the attribute estimation unit 23 sets the attribute information of the user of the mobile terminal 1b. Is assumed to be the same as the “work location” that is the attribute information of the user of the mobile terminal 1a, and the “friendship relationship” that is the attribute information of the user of the mobile terminal 1b is assumed to be “the user of the mobile terminal 1a” Is a colleague. " For example, when the relationship information between the user and the user of the mobile terminal 1b included in the attribute information of the user of the mobile terminal 1a is “friend”, the attribute estimation unit 23 sets the attribute information of the user of the mobile terminal 1b. Is a friend with the user of the mobile terminal 1a, and “where to go” that is the attribute information of the user of the mobile terminal 1b is the attribute information of the user of the mobile terminal 1a. It is presumed that it is the same as “a place to go often”.

  The attribute estimation unit 23 receives the sensor data of the portable terminal 1b input from the terminal information reception unit 21 (or the sensor data of the portable terminal 1b stored in the database in the user attribute estimation device 2 by the terminal information reception unit 21). Based on the above, the attribute information of the user of the mobile terminal 1b may be estimated, and the estimated attribute information may be stored in the attribute information storage unit 20. For example, the attribute estimation unit 23 may estimate the position information at 2 o'clock in the night as the position information of the home based on the history of position information in the sensor data of the mobile terminal 1b, or within one week. Location information for staying for 4 or 5 days or more may be used as home location information. In addition, for example, the attribute estimation unit 23 may estimate a day of the week that does not go to the work place as a holiday based on a history of position information in the sensor data of the mobile terminal 1b. In addition, for example, the attribute estimation unit 23 finds at least 2 days in the week at 2 o'clock at home based on the location information history and proximity terminal information in the sensor data of the mobile terminal 1b. You may estimate the user of the proximity terminal which was made as a family.

  The attribute estimation unit 23 receives the sensor data of the portable terminal 1b input from the terminal information reception unit 21 (or the sensor data of the portable terminal 1b stored in the database in the user attribute estimation device 2 by the terminal information reception unit 21). Based on the user attribute information stored by the attribute information storage unit 20, the user attribute information of the mobile terminal 1b may be estimated, and the estimated attribute information may be stored in the attribute information storage unit 20. For example, the attribute estimation unit 23 is based on the history of position information and proximity terminal information in the sensor data of the mobile terminal 1b, and information on the work location in the user attribute information, but the work location of each other is different. A user of the mobile terminal 1 who has been in the vicinity for one hour or more at either work location may be estimated as a work relationship. Further, for example, the attribute estimation unit 23 has the same work location based on the location information history and proximity terminal information in the sensor data of the mobile terminal 1b, and information on the work location in the user attribute information. Thus, the user of the portable terminal 1 who has been in the vicinity for more than two days a week at work may be estimated as a colleague.

  The attribute information transmission unit 24 transmits the attribute information of the user of the mobile terminal 1b estimated (input) by the attribute estimation unit 23 to the mobile terminal 1b.

  The user attribute estimation device 2 may further include a context estimation unit 25 (not shown) and a processing unit 26 (not shown) having the same functions as the context estimation unit 14 and the processing unit 15 included in the mobile terminal 1b. . The context estimation unit 25 estimates the context based on the attribute information estimated by the attribute estimation unit 23. The processing unit 26 performs processing based on the context estimated by the context estimation unit 25. Detailed processing contents of the context estimation unit 25 and the processing unit 26 are the same as those of the context estimation unit 14 and the processing unit 15 included in the mobile terminal 1b, and thus description thereof is omitted.

And is stored in the attribute information storage unit 13 of the portable terminal 1b. The above processes of S5 to S7 are periodically performed. However, at this stage, the attribute information storage unit 20 of the user attribute estimation device 2 does not include “friendship profile: friend with the mobile terminal 1a” as the attribute information of the user of the mobile terminal 1b.

  Here, if the detection unit 10 of the mobile terminal 1b detects the proximity of the mobile terminal 1a (step S8, detection step), the sensor data detected by the detection unit 10 of the mobile terminal 1b is the user attribute estimation device 2. (Step S9, terminal information transmission step). Next, the sensor information uploaded in S9 is received by the terminal information receiving unit 21 of the user attribute estimating device 2 (terminal information receiving step), and the attribute estimating unit 23 of the user attribute estimating device 2 receives the data at the proximity terminal.

Next, the attribute information transmission unit 24 of the user attribute estimation device 2 transmits (downloads) the user attribute information estimated in S10 to the portable terminal 1b (step S11, attribute information transmission step). The attribute information is received by the attribute information receiving unit 12 (attribute information receiving step) and stored in the attribute information storage unit 13 of the portable terminal 1b. At the stage of S10, the attribute information storage unit 20 of the user attribute estimation device 2 includes “friendship profile: friend with the mobile terminal 1a” as the attribute information of the user of the mobile terminal 1b. In addition, following S11, the context estimation unit 14 of the mobile terminal 1b estimates the context based on the attribute information received in S11 (context estimation step), and the context estimated by the processing unit 15 of the mobile terminal 1b. Processing based on the above may be performed (processing step).

Next, the terminal information receiving unit 21 of the user attribute estimation device 2 receives the local terminal information and the proximity terminal information from the portable terminal 1b. Next, the attribute information of the user of the portable terminal 1 a indicated by the received proximity terminal information is extracted from the attribute information storage unit 20 by the extraction unit 22 of the user attribute estimation device 2.

Next, the attribute information receiving unit 12 of the mobile terminal 1 b receives the attribute information of the user of the mobile terminal 1 b from the user attribute estimation device 2. Generally, users of mobile terminals 1 that are close to each other have an intimate relationship. In many cases, the attribute information between users who are intimate relations are identical or similar. The user attribute estimation device 2 can estimate the attribute information of the user of the portable terminal 1b based on the attribute information of the user of the portable terminal 1a by adopting the above configuration. For example, even if there is no information such as an action history related to the mobile terminal 1b or the user of the mobile terminal 1b or the amount of information is small, based on the attribute information of the user of the mobile terminal 1a that is intimately related to the user of the mobile terminal 1b Thus, the attribute information of the user of the mobile terminal 1b can be estimated with higher accuracy. That is, the user attribute estimation apparatus 2 can improve the estimation accuracy of user attribute information. Moreover, the portable terminal 1b receives (acquires) the attribute information of the user of the portable terminal 1b accurately estimated from the user attribute estimation device 2 only by transmitting the own terminal information and the proximity terminal information to the user attribute estimation device 2. )can do.

Generally, users of mobile terminals 1 that are close to each other have an intimate relationship. In many cases, the attribute information between users who are intimate relations are identical or similar. The user attribute estimation device 2 can estimate the attribute information of the user of the portable terminal 1b based on the attribute information of the user of the portable terminal 1a. For example, even if there is no information such as an action history related to the mobile terminal 1b or the user of the mobile terminal 1b or the amount of information is small, based on the attribute information of the user of the mobile terminal 1a that is intimately related to the user of the mobile terminal 1b Thus, the attribute information of the user of the mobile terminal 1b can be estimated with higher accuracy.

And since a process is performed based on the accurately estimated context, for example, a process more useful to the user is performed, so that convenience for the user is improved.

  In the prior art, since a terminal newly participating in the recommendation service has no past history information, there is a problem that estimation accuracy is low and it takes a certain period of time to obtain a correct estimation result. In addition, the old terminal has a problem that the accuracy of the sensor device is poor or the sensor itself is not activated due to the influence of battery consumption, and the estimation accuracy is low. According to the user attribute estimation system 3 according to the first embodiment, it is possible to improve the estimation accuracy of the own terminal and reduce the time by using the more likely estimation result of other terminals and proximity information.

  For example, when an acquaintance (family / colleague) participates in the recommendation service, the mobile terminal 1b newly subscribed to the service can use the information of the acquaintance's mobile terminal 1a for estimation. Specifically, when the acquaintance is a family member, the home position can be estimated with higher accuracy, and when the acquaintance is a colleague of the company, the work location can be estimated with higher accuracy. In addition, for example, when there is a mobile terminal 1a in which profile information has been registered in advance and a mobile terminal 1b in which profile information has not been registered, and the behavior patterns of these users (such as shops that are frequently used) are similar, Information for recommending to the mobile terminal 1d can be estimated from hobbies and preferences. In addition, for example, when there is a mobile terminal 1a in which the position information function of GPS / WiFi (registered trademark) is enabled and a mobile terminal 1b in which the position information function is disabled, it is detected that the mobile terminal 1b is close to the mobile terminal 1a. The current position of the mobile terminal 1b can be estimated from the current position of the mobile terminal 1a.

  In the estimation algorithm of the prior art, when highly accurate estimation of the attribute information and recommendation information of the user of the mobile terminal 1b is performed, it is necessary to acquire a history for a certain period. According to the user attribute estimation system 3 of the first embodiment, it is possible to perform estimation in a short period by using information of the portable terminal 1a that has been estimated.
