The information providing apparatus 100 according to the present embodiment provides information according to the analysis of a bored person (user). For example, in a certain area (field, object, matter), some people who are bored will continue and others will not. In addition, there are some areas that even people who tend to get bored may or may not continue. In this embodiment, the information providing apparatus 100 finds an area where a bored person can become absorbed (addicted).

Boring people are, for example, people who are interested in a specific area (field, object, matter) for a below-average period of time, but the number of searches and spending during that period is above average. . In other words, they are people who are enthusiastic and enthusiastic about a specific area for a period of time and intensively collect information and consume, but they do not last long.

(User comparison)
The information providing device 100 compares a person who is bored with a person who was bored in the past but became a fan. A person who was bored in the past but became a fan is originally a person who is bored, but even after the period in which the bored person usually has an interest or interest, it continues to be a fan. a person who continues A fan is a person who has deeply engaged in certain actions (checking information, collecting goods, etc.) in a specific area for a long period of time.

(experience comparison)
The information providing device 100 compares people who have turned into fans and people who have not, even among people who tend to get bored. Among bored people, those who have become fans are those who are naturally bored, but who have found a field in which they can be absorbed and become fans.

[1-1. Estimation and information provision of boredom users]
As shown in FIG. 1, the information providing device 100 collects user information (search query, purchase history, location history, etc.) on the user U via the network N (see FIG. 2) (step S1). For example, the information providing apparatus 100 collects location information, attribute information, history information, etc. of the user U directly or indirectly via the network N (see FIG. 2). In addition, when the information providing apparatus 100 receives a request for searching, electronic commerce, etc. from the terminal device 10 of each user U, the information providing apparatus 100 acquires search queries, purchase information, location information, etc., and accumulates them as history information. good too.

Subsequently, for each user, the information providing apparatus 100 estimates an interest or an area of interest of the user from the user information (search query, purchase history, location history, etc.) (step S2). For estimation, an estimation model for each region by machine learning can be used. For example, the information providing apparatus 100 learns the characteristics of the user information (search query, purchase history, location history, etc.) of a user who definitely belongs to each area, and when user information is input, the information providing apparatus 100 becomes absorbed in a specific area. It is possible to build and use a model to estimate whether

Subsequently, based on the user information, the information providing apparatus 100 estimates the degree and period of interest of the user U in each area (step S3). That is, for each user, the information providing apparatus 100 estimates, based on the user information, the level of interest in each area and how long the user has been absorbed in the area. This can be achieved by using a level estimation model for each region based on machine learning. The level estimation model, for example, the information providing apparatus 100 identifies in advance a person of each level (low/medium/high, or 5-level evaluation, etc.) according to the degree and period of interest, and user information of the identified person It can be realized by learning to output the level when inputting.

Subsequently, the information providing apparatus 100 identifies the user U whose interests tend to change (boring person) based on the degree and period of interest of the user U in each area (step S4). . A bored person is, for example, a person who does not maintain interest in each area (a person who does not continue a specific hobby). For example, the information providing apparatus 100 identifies a user whose interest frequently shifts from one area to another (the period of interest in a specific area is shorter than the average period) as a bored person.

At this time, the information providing apparatus 100 estimates the average value (or median value) of the period of interest (interested period) for each region, and determines that the user U for a period shorter than the estimated average value has a change in interest. You may specify as the user U who is easy to get bored (person of boredom). For example, the information providing apparatus 100 causes the model to learn the transition characteristics of the region in which the specified user is interested. Then, based on the learning result, an area in which the user is likely to be interested in the future (area in which the user is likely to be interested next) is estimated.

Next, the information providing apparatus 100 determines that, among the users U whose interests are likely to change, the user information of the users U is similar to the user information of users whose interests are less likely to change (people who are not bored). User U is identified (step S5).

Subsequently, the information providing device 100 generates recommendation information for the specified user U based on the user information of the specified user U (step S6). For example, the information providing apparatus 100 generates recommendation information that maintains or enhances the user's U interest in the current area of interest. Alternatively, based on the user information of the specified user U, the information providing apparatus 100 provides recommendation information regarding an area in which the user U may be interested in the future (area in which the user U is likely to be interested next). Generate.

It should be noted that the user information of the identified user (the user whose interest is likely to change) and the user information of the user whose interest is difficult to change are similar but do not exactly match. That is, there are points in common and points of difference in the similar user information. Therefore, the information providing apparatus 100 focuses on the difference in the user information, and out of the user information of the user whose interest is unlikely to change, the information (difference) that is not included in the user information of the specified user. point), recommendation information for the specified user may be generated and information may be provided to the user.

Further, the information providing apparatus 100 may analyze the features (order, chronological features) of areas in which the bored user U is interested, based on the user information. For example, the information providing apparatus 100 performs Markov process analysis on the Word2vec vector space. Note that Word2vec is just one example of natural language processing. In addition, fashion (chronological order of buzzwords and regions) and the like may be taken into consideration. Then, the information providing apparatus 100 may generate recommendation information by estimating an area in which the user U may be interested in the future.

In addition, there is a possibility that the action specific to the fan compared to the bored person is the charm of the area that the bored person has not yet noticed. At this time, if the information providing apparatus 100 extracts items that the bored person is not interested in among the items that the fan is interested in, the information providing apparatus 100 generates recommendation information that will lead to the discovery of a new attraction appealing to the bored person. can do.

In addition, there is a possibility of surprising combinations that fans have not yet noticed in areas that are more peculiar to boredom people than fans. At this time, the information providing apparatus 100 can create a long-distance combination plan by extracting what the fan is not interested in among the things that the bored person is interested in.

In addition, if necessary, the degree of relevance may be cut off so as to exclude those that are too close. In addition, it is also possible to compare the characteristics and interests of bored people and fans, narrow them down to things that are unique to bored people, and use them as ideas for collaboration and product planning.

Subsequently, the information providing device 100 provides information to the terminal device 10 of the specified user U via the network N (see FIG. 2) (step S7). For example, the information providing apparatus 100 provides information such that the interest in the user U's current interest in the area continues or increases. Alternatively, the information providing device 100 provides the terminal device 10 of the identified user U with information about the area that the user U is likely to be interested in next.

For example, the information providing apparatus 100 estimates an area that the user is likely to be interested in next based on similar user behavior, and provides information about that area. At this time, the information providing apparatus 100 may provide information on an area in which the user is likely to be interested next, at the timing when the user is losing interest in the previous area (timing at which the user loses interest). good. For example, the information providing apparatus 100 can be used when the user's actions on the previous area are decreasing (the frequency or number of times such as checking new information on a certain area or purchasing a new product is lower than before, or threshold or average When the following cases occur, it may be determined that the user is losing interest in the previous area, and information on the next area that the user is likely to be interested in may be provided.

Further, the information providing apparatus 100 may identify a person whose user information is similar to a professional person (a person who keeps getting hooked, a person who has a high level) from among people who tend to get bored easily. A professional person is, for example, a person who has a long-lasting interest in a certain field (a person who continues a particular hobby). A professional can be called an expert, an expert, or a maniac or an otaku. The information providing apparatus 100 may then identify the difference between the identified user and the professional, and provide information based on the identified difference.

For example, the information providing apparatus 100 changes the method of providing information depending on whether the user U is a person who tends to get bored. Alternatively, the information providing apparatus 100 makes the user U, who tends to get bored, become a professional by proposing an action like a professional. In addition, the information providing apparatus 100 analyzes those who have become professionals and those who have not become professionals among the bored people, and sorts them into those who change the way of providing information and those who want to become professionals. At this time, the information providing apparatus 100 analyzes people who have become professional and people who have not become professional among the bored people, and finds people who were likely to become fans but are getting bored. , Follow this person to become a fan.

As described above, in this embodiment, the information providing apparatus 100 estimates the history of the user's interest area (change in interest) from the user information. Next, the information providing apparatus 100 determines whether or not the user is a user whose interests tend to change (a user who tends to get bored) based on the estimation result. The information providing apparatus 100 identifies users whose user information is similar to the user information of users whose interests are less likely to change, among users whose interests are more likely to change. Then, the information providing apparatus 100 generates recommendation information for the user based on the user information of the specified user, and provides information to the user.
