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

[0002] Conventionally, various techniques for estimating user behavior have been provided, such as a technique for estimating user behavior based on user location information and operation information of power devices that accept user operations (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-218801 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is room for improvement in the above-mentioned conventional technology. For example, the above-mentioned conventional technology only estimates user behavior based on user location information and the operation of power appliances, making it difficult to capture deviations in user behavior. Therefore, it is desirable to be able to appropriately estimate user behavior.

[0005] The present application has been made in view of the above, and aims to provide an information processing device, an information processing method, and an information processing program that appropriately determine deviations in user behavior. [Means for solving the problem]

[0009] Hereinafter, a detailed description will be given of an information processing device, an information processing method, and an information processing program (hereinafter referred to as an "embodiment") according to the present application, with reference to the drawings. Note that the information processing device, the information processing method, and the information processing program according to the present application are not limited to the embodiment. Furthermore, the same components in the following embodiments are denoted by the same reference numerals, and redundant description will be omitted.

[0010] (Embodiment) [1. Information Processing] [1-1. Overall overview] An example of information processing according to an embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram illustrating an example of information processing according to an embodiment. FIG. 1 illustrates a case in which an information processing device 100 performs information processing on a group GP1 among a plurality of groups GP1 to GP3, etc., in which a plurality of users are classified based on a predetermined criterion (also referred to as "user classification criteria"), with the group GP1 being the target group and a user U1 belonging to the group GP1 being the target user. FIG. 1 illustrates an example in which the user's lifestyle is used as the user classification criterion, but the user classification criterion is not limited to the user's lifestyle and any arbitrary criterion can be adopted. For example, the user classification criterion may be more detailed. For example, the user classification criterion may be family, residential area, workplace, hobbies, etc. Note that the above is merely an example, and the user classification criterion may be any criterion that can group a plurality of users based on any commonality.

[0011] 1, the information processing device 100 determines whether the behavior of user U1, who is a target user, is a behavior (also referred to as a "deviant behavior") that deviates from behavior (also referred to as a "general behavior") that is highly common among users belonging to group GP1. Also, FIG. 1 illustrates an example of a process in which the information processing device 100 changes the group to which the target user belongs when it is determined that the target user is engaging in deviant behavior.

[0012] 1, for simplicity, an example is given in which each user belongs to only one group, but each user may belong to multiple groups. That is, while an example is given in which users belonging to each group are classified to be exclusive, overlapping users belonging to groups may be permitted, and each user may belong to multiple groups if there are multiple groups to which the user belongs.

[0013] [1-1-1. Information Processing System Configuration] In the following, the configuration of the information processing system 1 will be described first with reference to FIG. 2, and then the processing of FIG. 1 will be described in detail. FIG. 2 is a diagram illustrating an example of the configuration of the information processing system according to an embodiment. As shown in FIG. 2, the information processing system 1 includes a terminal device 10 and an information processing device 100. Although one terminal device 10 is illustrated in FIG. 2, the information processing system 1 includes multiple terminal devices 10. For example, the information processing system 1 includes terminal devices 10 used by each user. For example, if there are 10,000 users, the information processing system 1 includes more than 10,000 terminal devices 10. The terminal devices 10 and the information processing device 100 are connected to each other via a predetermined network N so as to be able to communicate with each other via a wired or wireless connection. Note that the information processing system 1 may include multiple information processing devices 100.

[0014] The terminal device 10 is an information processing device used by a user. The terminal device 10 is realized by, for example, a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like. For example, the terminal device 10 is a smartphone used by a user. Note that, hereinafter, the terminal device 10 may be referred to as a user. That is, hereinafter, the user may be read as the terminal device 10.

[0015] The terminal device 10 may also detect various sensor information using various sensors such as a GPS (Global Positioning System) sensor. The terminal device 10 may also have an acceleration sensor function and detect and acquire acceleration information (sensor information) during the user's movement. The terminal device 10 may also have various functions such as a temperature sensor and an air pressure sensor and be able to detect and acquire environmental information about the user's environment, such as temperature and air pressure. The terminal device 10 may also have various functions such as a heart rate sensor and be able to detect and acquire biometric information about the user. For example, a user of the terminal device 10 may wear a wearable device capable of communicating with the terminal device 10, thereby enabling the terminal device 10 to acquire the user's own context information. For example, a user of the terminal device 10 may wear a wristband-type wearable device capable of communicating with the terminal device 10, thereby enabling the terminal device 10 to acquire information about the user's own heart rate (pulse).

[0016] Furthermore, the terminal device 10 collects various types of information other than the sensor information and transmits the collected information to the information processing device 100. The terminal device 10 transmits behavioral information indicating the behavior of the user using the terminal device 10 to the information processing device 100. The terminal device 10 transmits behavioral information related to a payment made using the terminal device 10 to the information processing device 100. The terminal device 10 transmits behavioral information related to a payment (settlement) made at a store using the terminal device 10 to the information processing device 100. The terminal device 10 transmits behavioral information indicating an operation by the user to the information processing device 100. The terminal device 10 transmits behavioral information indicating the behavior of the user on the Internet to the information processing device 100. For example, the terminal device 10 transmits behavioral information including posted information (input information) such as posts by the user to a social networking service (SNS) to the information processing device 100. For example, the terminal device 10 transmits behavioral information including posted information posted by the user to Twitter (registered trademark), Facebook (registered trademark), Instagram (registered trademark), etc. to the information processing device 100.

[0017] The terminal device 10 receives various types of information from the information processing device 100. The terminal device 10 receives information corresponding to a group to which the user belongs from the information processing device 100. The terminal device 10 receives an advertisement corresponding to a group to which the user belongs from the information processing device 100.

[0018] The information processing device 100 is a computer that determines whether the behavior of a target user who belongs to a target group among multiple groups into which multiple users are classified based on classification criteria is deviant behavior that deviates from the general behavior of the target group. The information processing device 100 determines whether the behavior of the target user who belongs to the target group is deviant behavior that deviates from the general behavior of the target group by referring to information indicating the general behavior of the target group. Furthermore, when the information processing device 100 determines that the target user is engaging in deviant behavior, it changes the group to which the target user belongs.

[0019] Furthermore, the information processing device 100 performs a service (information providing service) of providing information to a user according to a group to which the user belongs. The information processing device 100 delivers an advertisement corresponding to a group to which the user belongs to a terminal device 10 used by the user according to a group to which the user belongs. For example, the information processing device 100 delivers an advertisement corresponding to a group to which the user belongs in response to a request from the terminal device 10 used by the user.

[0020] [1-2. Information processing example] Hereinafter, a case where a characteristic determining whether or not user U1 has engaged in deviant behavior as a target user will be described as an example using FIG. 1. In FIG. 1, group GP1 will be described as groups GP1-1, GP1-2, etc. depending on the group to which it belongs, but when there is no particular distinction, it will be described as group GP1. In FIG. 1, group GP1-1 corresponds to group GP1 before the change, and group GP1-2 corresponds to group GP1 after the change. Specifically, group GP1-1 corresponds to group GP1 to which user U1 belongs, and group GP1-2 corresponds to group GP1 after user U1 has been excluded.

[0021] Similarly, when groups GP2, GP3, etc. are described without any particular distinction, they will be referred to as groups GP2, GP3, etc. For example, group GP2-1 corresponds to group GP2 before the change, and group GP2-2 corresponds to group GP2 after the change. Specifically, group GP2-1 corresponds to group GP2 before user U1 was added, and group GP2-2 corresponds to group GP2 after user U1 was added.

[0022] In FIG. 1, as shown in group GP1-1, users U1, U4, U12, U21, etc. belong to group GP1 before the change. For example, group GP1 is assumed to be a group to which users with a lifestyle corresponding to living alone belong. Furthermore, as shown in group GP2-1, users U3, U25, U45, U65, etc. belong to group GP2 before the change. For example, group GP2 is assumed to be a group to which users with a lifestyle corresponding to semi-cohabitation belong. Furthermore, as shown in group GP3-1, users U2, U38, U108, U123, etc. belong to group GP3. For example, group GP3 is assumed to be a group to which users with a lifestyle corresponding to cohabitation belong.

[0023] Group content information SM1 indicating the content of group GP1 includes general behavior GB1, which is a general behavior corresponding to group GP1. General behavior GB1 includes various behaviors common to users who live alone. For example, general behavior GB1 includes behaviors that are commonly performed by a predetermined percentage (e.g., 60%) or more of the multiple users belonging to group GP1. For example, general behavior GB1 includes various behaviors such as being at home on weekday evenings.

[0024] Furthermore, group content information SM2 indicating the content of group GP2 includes general behavior GB2, which is a general behavior corresponding to group GP2. General behavior GB2 includes various behaviors common to users who are semi-cohabiting. For example, general behavior GB2 includes behaviors that are commonly performed by a predetermined percentage (e.g., 60%) or more of the multiple users belonging to group GP2. For example, general behavior GB2 includes various behaviors such as being at another user's home on a weekday evening.

[0025] The information processing device 100 acquires behavioral information of user U1, who is a target user (step S11). For example, the information processing device 100 receives the behavioral information of user U1 from the terminal device 10 used by user U1. In FIG. 1, the information processing device 100 acquires behavioral information indicating behavior AC101 of user U1, as shown in target behavioral information TD1. For example, the information processing device 100 acquires behavioral information indicating behavior AC101 in which user U1 is located at the home of another user (e.g., user U5) on a weekday evening.

[0026] Then, the information processing device 100 determines whether the behavior of user U1 is a deviant behavior that deviates from the general behavior of group GP1 (step S12). If the behavior of the target user does not correspond to the general behavior corresponding to the target group, the information processing device 100 determines that the behavior of the target user is a deviant behavior. On the other hand, if the behavior of the target user corresponds to the general behavior corresponding to the target group, the information processing device 100 determines that the behavior of the target user is not a deviant behavior.

[0027] 1, the information processing device 100 determines whether the behavior AC101 of the user U1 is a deviant behavior that deviates from the general behavior GB1 of the group GP1, as shown in the result information RS1. For example, the information processing device 100 determines that the behavior AC101, in which the user U1 is at the home of another user (e.g., user U5) on a weekday evening, is a deviant behavior from the general behavior GB1 of the group GP1, because the behavior AC101 is not included in the general behavior GB1 of the group GP1. In this way, the information processing device 100 determines that the lifestyle of the user U1 does not correspond to the lifestyle of the group GP1, because the behavior AC101 of the user U1 does not correspond to the general behavior GB1 corresponding to the group GP1.

[0028] When the information processing device 100 determines that the target user's behavior is a deviation from the general behavior of the target group, it determines to change the group to which the target user belongs from the target group to another group. Furthermore, when the information processing device 100 determines that the target user's behavior is not a deviation from the general behavior of the target group, it determines not to change the group to which the target user belongs from the target group. In FIG. 1, the information processing device 100 determines that the behavior AC101 of user U1 is a deviation from the general behavior GB1 of group GP1, and therefore determines to change the group to which user U1 belongs from group GP1 to another group.

[0029] The information processing device 100 determines another group to which the group to which user U1 belongs will be changed, based on a comparison between the general behavior corresponding to each of a plurality of groups and the deviant behavior of user U1. In Fig. 1, the information processing device 100 determines another group to which the group to which user U1 belongs will be changed, based on a comparison between the general behaviors GB2, GB3, etc. corresponding to each of a plurality of groups GP2, GP3, etc. and the deviant behavior of user U1. The information processing device 100 determines to change the group to which user U1 belongs to another group, among the plurality of groups, to which user U1's behavior AC101, which is a deviant behavior from the general behavior GB1 of group GP1, corresponds.

[0030] In FIG. 1, the information processing device 100 determines to change the group to which user U1 belongs from group GP1 to group GP2 because the behavior AC101 of user U1 corresponds to the general behavior GB2 of group GP2. As a result, the information processing device 100 changes the group to which user U1 belongs from group GP1 to group GP2, as shown in group GP1-2 and group GP2-2. Specifically, the information processing device 100 removes user U1 from group GP1, as shown in group GP1-2. Furthermore, the information processing device 100 adds user U1 to group GP2, as shown in group GP2-2. In this way, the information processing device 100 changes the group to which user U1 belongs in accordance with the behavior AC101 of user U1.

[0031] As such, in FIG. 1, the information processing device 100 determines that the lifestyle of user U1 has changed from living alone to semi-cohabitation. The information processing device 100 provides information in response to the change in the lifestyle of user U1. For example, the information processing device 100 recommends wedding venues to user U1. For example, the information processing device 100 provides an advertisement for the wedding venue to the terminal device 10 used by user U1. Note that the information processing device 100 may determine whether the lifestyle of the user is semi-cohabitation based on the time spent by the user at the deviation destination.

[0032] Furthermore, the information processing device 100 may update the general behavior corresponding to the changed group based on the users belonging to the changed group. The information processing device 100 determines the general behavior corresponding to the changed group based on the users belonging to the changed group. For example, the information processing device 100 determines the general behavior of the changed group to be a behavior that is commonly performed by a predetermined ratio or more of users in the changed group.

[0033] As described above, the information processing device 100 can appropriately determine the deviation of the user's behavior by determining whether the target user's behavior is a deviant behavior that deviates from the general behavior of the target group based on information indicating the general behavior of the target group and the target user's behavior.

[0034] In this way, the information processing device 100 groups users, defines common behaviors among the group as general behaviors, and determines that a behavior different from the general behaviors has been committed as a deviant behavior. This allows the information processing device 100 to automate the definition of general behaviors and the definition of deviant behaviors.

[0035] [1-3. Other processing examples] Note that the above-described process is merely an example, and the information processing device 100 may perform various processes using various information. For example, the information processing device 100 may use the process of determining deviant behavior for various purposes other than identifying a user's lifestyle. For example, the information processing device 100 may use the process of determining deviant behavior for stalker detection. For example, when the information processing device 100 determines that a user has engaged in deviant behavior, it may determine that the user is a stalker candidate.

[0036] Furthermore, for example, the information processing device 100 may use the process of determining deviant behavior for recommendations regarding job hunting or career change. For example, the information processing device 100 may determine that the group from which common sense is extracted has changed based on the degree of evolution of the deviation, and may estimate the stage of the user's lifestyle based on this. For example, if the user's behavior deviates from the general behavior of a group of ordinary university students (first group), the information processing device 100 may determine to change the user's group from the first group to a group of job-hunting students (second group). Then, the information processing device 100 transmits an advertisement related to job hunting to the terminal device 10 used by the user.

[0037] As described above, the information processing device 100 sets a general behavior based on the commonality of the behaviors of users belonging to each group. For example, the information processing device 100 may determine the behavior performed by the most users as the general behavior for that group. Furthermore, the information processing device 100 may identify, for each group, a behavior whose difference from the general behavior exceeds a predetermined threshold as a deviant behavior. Furthermore, the information processing device 100 may provide information according to the deviant behavior.

[0038] As described above, the information processing device 100 defines (determines) general behavior (general behavior). For example, the information processing device 100 sets it from various location logs, etc. For example, the information processing device 100 determines general behavior based on common sense for the group (such as the area), and identifies deviations from this general behavior. For example, if there is a deviation, the information processing device 100 estimates the user's behavior according to the content of the deviation. For example, the information processing device 100 may identify deviations for each behavior type. For example, the information processing device 100 may identify deviations for each motif, such as eating or playing. For example, the information processing device 100 may determine a group to which the user belongs based on the degree of conformity with the deviation from general behavior corresponding to the motif for each group.

[0039] As described above, the information processing device 100 may determine that the user's lifestyle has changed if the user's behavior is similar to the general behavior (common sense) of other groups. For example, the information processing device 100 determines the group to which the user belongs based on the user's deviant behavior. For example, the information processing device 100 can determine the user's lifestyle based only on location information.

[0040] For example, if a user deviates from the user's personal route between home and work, the information processing device 100 may determine that the user has engaged in deviant behavior. For example, the information processing device 100 compares the user's behavior with the common sense (common behavior) of the group to which the user belongs, and if the user's behavior deviates from the common sense (common behavior) of the group to which the user belongs, determines that the user's behavior is deviant behavior.

[0041] For simplicity of explanation, the above-described process shows a case where a deviation is determined and a group is changed based on a single user behavior. However, the process of determining a deviation and changing a group is not limited to the above. For example, the information processing device 100 may determine whether to change a group based on a score (group change score). For example, the information processing device 100 determines a group change score for a user based on the user's behavior. In this case, the information processing device 100 executes a process in which the points (values ​​to be added) added to the user's group change score vary depending on the user's deviation behavior pattern, and points are added to the user's group change score for each deviation. Then, the information processing device 100 may decide to change the user's group when the user's group change score exceeds a threshold.

[0042] For example, the information processing device 100 may perform processing that takes into consideration that common sense (general behavior) may change at a slower pace than deviations. For example, the information processing device 100 may add a new group to existing groups, taking into consideration a pattern in which a completely new group emerges after several years.

[0043] For example, if online activities become more active due to the COVID-19 pandemic and an increase in people behaving in ways that are not part of existing groups (and that are considered "deviant" in all groups), new groups related to online activities may be added. For example, the information processing device 100 may perform an update process for grouping and extracting common sense less frequently (for example, every few months to years) than the frequency of checking (determining) deviations (for example, every few days to weeks).

[0044] 2. Configuration of Information Processing Device Next, the configuration of the information processing device 100 according to the embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the configuration of the information processing device according to the embodiment. As shown in Fig. 3, the information processing device 100 has a communication unit 110, a storage unit 120, and a control unit 130. Note that the information processing device 100 may also have an input unit (e.g., a keyboard, a mouse, etc.) that accepts various operations from an administrator of the information processing device 100, and a display unit (e.g., a liquid crystal display, etc.) that displays various information.

[0045] (Communication unit 110) The communication unit 110 is realized by, for example, a network interface card (NIC) etc. The communication unit 110 is connected to a network via a wired or wireless connection, and transmits and receives information to and from, for example, a terminal device 10 included in the information processing system 1.

[0046] (Storage unit 120) The storage unit 120 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk. As shown in FIG. 3 , the storage unit 120 according to the embodiment includes a user information storage unit 121, a behavior information storage unit 122, and a group information storage unit 123.

[0047] (User information storage unit 121) The user information storage unit 121 according to the embodiment stores various information related to a user. For example, the user information storage unit 121 stores user attribute information. FIG. 4 is a diagram illustrating an example of the user information storage unit according to the embodiment. The user information storage unit 121 shown in FIG. 4 includes items such as "user ID," "age," "gender," "home," "place of work / school," and "interests."

[0048] "User ID" indicates identification information for identifying a user. For example, a user identified by user ID "U1" corresponds to user U1 shown in the example of Figure 1. "Age" indicates the age of the user identified by the user ID. Note that "Age" may be a specific age of the user identified by the user ID, such as 35 years old. "Gender" indicates the gender of the user identified by the user ID.

[0049] Furthermore, "home" indicates the location information of the user's home identified by the user ID. In the example shown in FIG. 4, "home" is illustrated as an abstract code such as "LC11," but it may also be information indicating latitude and longitude. Furthermore, for example, "home" may also be the name of a region or an address.

[0050] Furthermore, "Place of Work / School" indicates the location information of the place of work (place of work) where the user identified by the user ID works or the school or other school the user attends. In the example shown in FIG. 4, "Place of Work / School" is illustrated as an abstract code such as "LC12," but it may also be information indicating latitude and longitude. Furthermore, for example, "Place of Work / School" may also be the name of an area or an address.

[0051] Furthermore, "interests" indicate the interests of a user identified by a user ID. That is, "interests" indicate subjects in which a user identified by a user ID is highly interested. Note that, in the example shown in FIG. 4, each user has one "interest," but there may be multiple "interests."

[0052] For example, in the example shown in FIG. 4, the age of the user identified by the user ID "U1" is "20s" and the gender is "male." Also, for example, the user identified by the user ID "U1" indicates that his home address is "LC11." Also, for example, the user identified by the user ID "U1" indicates that his workplace / school address is "LC12." Also, for example, the user identified by the user ID "U1" indicates that he is interested in "sports."

[0053] The user information storage unit 121 may store various types of information according to the purpose, without being limited to the above. For example, the user information storage unit 121 may store information on the demographic attributes and psychographic attributes of the user. For example, the user information storage unit 121 may store information such as name, family structure, income, interests, and lifestyle.

[0054] (Behavior information storage unit 122) The behavior information storage unit 122 according to the embodiment stores various information related to user behavior. Fig. 5 is a diagram illustrating an example of the behavior information storage unit according to the embodiment. For example, the behavior information storage unit 122 stores various behavior information such as the behavior of each user. The behavior information storage unit 122 shown in Fig. 5 includes items such as "user ID," "behavior ID," "date and time," "location," and "content."

[0055] "User ID" indicates identification information for identifying a user. For example, a user identified by user ID "U1" corresponds to user U1 shown in the example of Figure 1. "Action ID" indicates information for identifying a user's action. "Date and time" indicates the date and time when the corresponding user action was performed. Note that while Figure 5 illustrates "dt11" and the like, "Date and time" may also store a specific date and time such as "May 4, 2022, 10:31:58 PM."

[0056] Furthermore, "location" indicates the location information of the corresponding user at the corresponding date and time. Note that in Fig. 5, "location" is illustrated using an abstract symbol such as "LC11", but specific latitude and longitude information may also be stored in "location". Furthermore, "content" indicates the specific content of the corresponding user's activity.

[0057] For example, in the example shown in Figure 5, a user (user U1) identified by user ID "U1" has performed actions identified by action ID "AC11", action ID "AC15", action ID "AC19", etc.

[0058] For example, as shown in action AC11, user U1 is located at position LC11 at date and time dt11, indicating that he is at home. Also, as shown in action AC15, user U1 is located at position LC8 at date and time dt15, indicating that he ate at restaurant A. Also, as shown in action AC19, user U1 is located at position LC12 at date and time dt19, indicating that he is at work.

[0059] The behavioral information storage unit 122 may store various types of information according to the purpose, not limited to the above. Also, although Fig. 5 shows the case where the behavioral information is stored in the behavioral information storage unit 122 for each user ID, the behavioral information may be stored not only for each user ID but also, for example, in chronological order.

[0060] (Group information storage unit 123) The group information storage unit 123 according to the embodiment stores various information related to user classification. Fig. 6 is a diagram illustrating an example of the group information storage unit according to the embodiment. The group information storage unit 123 shown in Fig. 6 includes items such as "group ID," "group content information," and "user."
