Note that a journey is not limited to those related to medical care, but is the transition of a person's state related to a predetermined target. It may be something to do.

[Configuration of information processing system]
Prior to the description of FIG. 1, the configuration of the information processing system 1 will be described with reference to FIG. FIG. 2 is a diagram illustrating a configuration example of an information processing system according to the embodiment; As shown in FIG. 2 , the information processing system 1 includes a terminal device 10 and an information processing device 100 . The terminal device 10 and the information processing device 100 are connected via a predetermined network N so as to be communicable by wire or wirelessly. Note that the information processing system 1 shown in FIG. 2 may include a plurality of terminal devices 10 and a plurality of information processing apparatuses 100 .

The terminal device 10 is an information processing device used by a user. The terminal device 10 is realized by, for example, a smart phone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like. FIG. 1 shows a case where the terminal device 10 is a smart phone.

In addition, the terminal device 10 transmits various information and the like to the information processing device 100 . For example, the terminal device 10 transmits, to the information processing device 100, position information about the user, action information including information about a search query used by the user for searching, and the like. In addition, below, the terminal device 10 may be described as a user. That is, hereinafter, the user can also be read as the terminal device 10 . The terminal device 10 accepts various operations by the user. FIG. 1 shows a case where the user using the terminal device 10 is identified by the user ID "U1" (hereinafter referred to as "user U1").

Note that the terminal device 10 may have various sensors. For example, the terminal device 10 has a function such as a GPS (Global Positioning System) sensor and detects the position of the user. Further, the terminal device 10 may have various functions such as a temperature sensor and an air pressure sensor, and may be capable of detecting and acquiring environment information such as temperature and air pressure in which the user is placed. In addition, the terminal device 10 may have various functions such as a heartbeat sensor, and may be capable of detecting and acquiring biological information of the user. For example, a user using the terminal device 10 may be able to acquire information about the user himself/herself through the terminal device 10 by wearing a wearable device capable of communicating with the terminal device 10 . For example, a user using the terminal device 10 wears a wristband-type wearable device that can communicate with the terminal device 10, so that the terminal device 10 acquires information about the user's own heartbeat (pulse). It may be possible.

The information processing apparatus 100 estimates which stage the user is in among a plurality of stages of the journey based on the first behavior information among the acquired behavior information of the user. Below, as an example of the first behavior information, a case where a history of user's search behavior on the Internet is used will be described. Note that the first behavior information is not limited to search behavior, and any information may be used as long as it is information that can be used to estimate the stage of the user in the journey. For example, the first behavior information may be information about various behaviors of the user on the Internet.

Further, the information processing apparatus 100 estimates the user's emotion based on the second behavior information among the acquired user behavior information. In the following, as an example of the second action information, a case will be shown in which information on content browsed by the user is used. That is, a case is shown in which, as an example of the second behavior information, information on content provided (delivered) to the terminal device 10 used by the user is used. Note that the second behavior information is not limited to the content browsed by the user, and any information may be used as long as it is information that can be used to estimate the user's emotion. For example, the second action information may be the same information as the first action information.

From here, the flow of information processing will be described using FIG. First, the information processing device 100 acquires behavior information of the user U1 from the terminal device 10 used by the user U1 (step S11). For example, the information processing device 100 acquires the behavior history on the Internet of the user U1 from the terminal device 10 . In FIG. 1 , the information processing apparatus 100 acquires first action information regarding searches performed by the user U1 at dates dt11 and dt12.

The information processing apparatus 100 stores in the behavior information storage unit 122 the first behavior information indicating the content of the search performed by the user U1. In FIG. 1 , the information processing apparatus 100 performs a search using the search query “precision examination” by the user U1 on the date and time dt11, and performs a search using the search query “examination cost” on the subsequent date and time dt12. The first action information indicating that is stored in the action information storage unit 122 .

The information processing device 100 also provides the C content to the terminal device 10 used by the user U1 (step S12). For example, the information processing device 100 transmits the C content to the terminal device 10 used by the user U1 in response to a distribution request for the C content from the user U1. display. In FIG. 1 , the information processing apparatus 100 acquires second action information related to browsing of content performed by the user U1 at date and time dt15.

By transmitting the C content to the terminal device 10 used by the user U1, the information processing apparatus 100 stores second action information indicating browsing of the C content by the user U1 in the action information storage unit 122 . In FIG. 1 , the information processing apparatus 100 stores the second action information indicating that the user U1 browsed the C content on the date and time dt15 in the action information storage unit 122 .

Then, the information processing apparatus 100 estimates which stage the user U1 is in among a plurality of stages of a medical-related journey (hereinafter referred to as "journey JN1") (step S13). For example, the information processing apparatus 100 uses the information (hereinafter also referred to as “journey information JINF1”) related to the journey JN1 stored in the journey information storage unit 124 (see FIG. 7) to allow the user U1 to perform a plurality of stages in the journey JN1. Estimate which stage it is in. For example, the journey information JINF1 includes the first stage (stage J11), the second stage (stage J12) that is the next stage after stage J11, and the third stage (stage J13), etc., is included to indicate that there are multiple stages in the journey JN1. The journey information JINF1 also includes information (stage content information) indicating which stage each stage is in the journey JN1, information (condition information) indicating conditions for corresponding to each stage, and the like.

For example, in the journey information JINF1, the first stage of the medical-related journey JN1, stage J11, corresponds to information (stage content information) indicating that the stage is a stage in which people are worried about the cost of examinations. stored with the In addition, information (condition information) indicating that the user performs a search using the keywords "inspection" and "cost" is stored in association with step J11. . In addition, information indicating that the stage is a stage in which the patient feels uneasy about surgery (stage content information) is stored in association with stage J12. Also, information (condition information) indicating that the user performs a search using the keyword "surgery" or the like as a condition for matching the stage J12 is stored in association with the stage J12.

The information processing apparatus 100 searches the action history of the user U1 stored in the action information storage unit 122, and uses the first action information indicating the search action performed by the user U1 to estimate the stage of the user U1 in the journey JN1. do. In FIG. 1, the information processing apparatus 100 determines that the stage of the user U1 in the journey JN1 is the first stage based on the first behavior information indicating that the user U1 is performing a search using the keywords "inspection" and "cost" as search queries. Assume that it is stage J11, which is stage 1. Note that the user's emotion estimation described above is merely an example, and the information processing apparatus 100 may estimate the user's level through various processes, which will be described later.

Information processing apparatus 100 also estimates the emotion of user U1 (step S14). The information processing apparatus 100 searches the action history of the user U1 stored in the action information storage unit 122, and uses second action information indicating content provided to the user U1 to estimate the emotion of the user U1. In FIG. 1, the information processing apparatus 100 estimates the emotion of the user U1 based on the second behavior information indicating that the user U1 has been provided with the C content.

For example, the information processing apparatus 100 uses information (emotion information) indicating changes in emotion due to each content stored in the content information storage unit 123 to estimate the emotion of the user U1 to whom the C content is provided. As shown in the content information storage unit 123, the C content indicates that the emotional change is sadness and causes the user to feel sadness. Therefore, the information processing apparatus 100 presumes that the emotion of the user U1 is sadness. Note that the user's emotion estimation described above is merely an example, and the information processing apparatus 100 may estimate the user's emotion through various processes, but this point will be described later.

The information processing device 100 then determines information to be provided to the user U1 (step S15). In FIG. 1 , the information processing apparatus 100 determines content (provided content) to be provided to the user U1 from the content group stored in the content information storage unit 123 . The information processing apparatus 100 determines the provided content to be provided to the user U1 from among the content group stored in the content information storage unit 123, based on the stage J11 of the user U1 and the user U1's emotion "sadness". The information processing apparatus 100 determines the provided content to be provided to the user U1 using the information (provided target information) indicating the provided target of each content stored in the content information storage unit 123 . As shown in the content information storage unit 123, each content is associated with provision target information indicating the stage and emotion of a target user when the content is used as content for providing information.

Therefore, the information processing apparatus 100 compares the stage and emotion indicated by the provision target information of each content stored in the content information storage unit 123 with the stage J11 of the user U1 and the emotion "sadness" of the user U1. The content corresponding to the level and emotion of U1 is determined as the content to be provided. In FIG. 1, content A is associated with stage J11 and emotion "sadness" as information to be provided. Indicates that the content is suitable for Therefore, the information processing apparatus 100 selects the content A, which is associated with the level J11 and the emotion "sadness" as the provision target information among the contents stored in the content information storage unit 123, as content to be provided to the user U1. decide.

Then, the information processing device 100 provides information based on the provided content to the user U1 (step S16). In the example of FIG. 1, the information processing device 100 transmits the A content to the terminal device 10 used by the user U1.

In this way, the information processing apparatus 100 provides information to the user using two elements, the stage in the user's journey and the user's emotion. Therefore, the information processing apparatus 100 can provide appropriate information according to the user.

[1-1. Journey]
Note that the journey JN1 described above is merely an example, and journeys may be of various targets. Also, in the above example, a journey including only one transition (route) of the first stage, second stage, and third stage was shown, but the stages of the journey may branch. In this case, the journey may branch into any of multiple second stages depending on, for example, which query the user in the first stage uses.

For example, the information processing apparatus 100 receives user behavior information and information indicating the latest stage estimated for the user, uses a journey stage estimation model that outputs the stage estimated for the user, and uses the user's stage can be estimated. In this case, the information processing apparatus 100 inputs the behavior information of the user and the information indicating the latest stage estimated for the user to the journey stage estimation model, and based on the output result of the journey stage estimation model, the stage of the user U1 can be estimated.

For example, the journey stage estimation model may be a model (multi-class classification model) that outputs scores for each of a plurality of stages. In this case, the information processing apparatus 100 inputs the user's behavior information and the information indicating the latest stage estimated for the user to the journey stage estimation model, and the score output by the journey stage estimation model among the multiple stages is Assume the largest tier to be that user's tier.

For example, the information processing apparatus 100 may use the following route estimation model as the journey stage estimation model. In this case, for example, the information processing apparatus 100 learns the relationship between the transition of search queries used by the user and the stage (position) where the user is located on the transition (route) of the journey. For example, the information processing apparatus 100 can determine whether the user has input a predetermined search query, in what order the search queries have been input, how much time has passed since the user input the search query, and the user's state ( stage) to learn the corresponding relationship. For example, the information processing apparatus 100 learns a route estimation model that outputs the stage of the user's journey using history information of search queries input by the user.

In addition, in order to simplify the explanation, FIG. 1 shows the case where it is estimated to be the first stage (first stage). It may be a condition to be in the stage. For example, when estimating that the user's stage is the second stage (stage J12) of the journey JN1, the information processing apparatus 100 determines that the user's stage is the first stage (stage J11) of the journey JN1 at the time of estimation. It can be used as a condition. Note that the above is merely an example, and the information processing apparatus 100 may estimate that it is in the second stage or later from the time of the initial estimation.

In addition, FIG. 1 shows an example of estimating which stage a single journey is in order to simplify the explanation. You can presume that you are in the journey stage. That is, the information processing apparatus 100 may estimate the stages of the user on the assumption that the user undergoes a plurality of journeys in parallel. In this case, the information processing apparatus 100 may estimate that, if there are a plurality of stages of journeys that satisfy the condition of the user's first behavior information, all of the stages are met.

[1-2. emotions]
FIG. 1 shows an example of estimating a user's emotion based on content provided to the user. You may For example, the information processing apparatus 100 may estimate the user's emotion using an emotion estimation model that receives user behavior information as input and outputs information indicating an estimated emotion of the user. In this case, information processing apparatus 100 may input behavior information of user U1 into an emotion estimation model, and estimate the emotion of user U1 based on the output result of the emotion estimation model.

For example, the emotion estimation model may be a model (multi-class classification model) that outputs scores for each of a plurality of emotions. In this case, the information processing apparatus 100 inputs the user's behavior information into the emotion estimation model, and estimates the emotion with the highest score output by the emotion estimation model among the plurality of emotions as the user's emotion.

Further, the information processing apparatus 100 may estimate the user's emotion based on, for example, the details of the content selected by the user after entering the last search query. For example, the information processing apparatus 100 may set an emotion presumed to be strongly related to the content on a rule basis.

[1-3. Estimation process]
The process (estimation process) for estimating the stage or emotion of the user shown in FIG. 1 is merely an example, and the information processing apparatus 100 may perform the estimation process using various information. For example, the information processing apparatus 100 may estimate the stage of the journey of the user who is the target of information provision using a route estimation model learned about similar users similar to the user who is the target of information provision. Further, the information processing apparatus 100 may estimate an emotion using an emotion estimation model, or provide information according to a combination of a journey stage and an emotion.

[1-4. Information provision]
FIG. 1 shows a case where the content to be provided to the user (provided content) is determined using the provision target information associated with each content. Content may be determined. For example, the information processing apparatus 100 may determine content to be provided to the user using a model for determining content to be provided (content determination model). For example, the information processing apparatus 100 determines content to be provided to the user using a content determination model that inputs information indicating the user's stage and information indicating the emotion, and outputs information indicating content to be provided to the user. may In this case, the information processing apparatus 100 may input behavior information of the user U1 into the content determination model and determine the emotion of the user U1 based on the output result of the content determination model.

For example, the content decision model may be a model that outputs a score for each of multiple pieces of content. In this case, the information processing apparatus 100 inputs the information indicating the user's stage and the information indicating the emotion to the content determination model, and sends the content with the highest score output by the content determination model among the plurality of contents to the user. Decide on the provided content.

[1-5. Provide other information]
In the above-described example, an example of providing content is shown as an example of providing information, but the information processing apparatus 100 may provide various information other than content. For example, the information processing apparatus 100 may provide various information based on the estimation result of the estimation process.

The information processing apparatus 100 may provide the target user with information indicating a search query used for a search by a user having an emotion similar to the estimated emotion of the target user (estimated emotion). For example, the information processing apparatus 100 may provide the target user with information indicating a search query used for a search by a user who has the same emotion as the estimated emotion (estimated emotion) of the target user.

In addition, the information processing apparatus 100 may provide the target user with information indicating a search query used for a search by a user at a stage similar to the stage (estimation stage) of the estimated target user. For example, the information processing apparatus 100 may provide the target user with information indicating a search query used for a search by a user at the same stage as the estimated stage of the target user (estimation stage).

The information processing apparatus 100 indicates a search query used for a search by a user who has an emotion similar to the estimated target user's emotion (estimated emotion) and is at a stage similar to the estimated target user's stage (estimated stage). Information may be provided to a target user. For example, the information processing apparatus 100 indicates a search query used for a search by a user who has the same emotion as the estimated target user's emotion (estimated emotion) and is at the same stage as the estimated target user's stage (estimated stage). Information may be provided to a target user.

The information processing apparatus 100 may provide information indicating the estimation result of the user's emotion. The information processing apparatus 100 may transmit information indicating the estimation result of the user's emotion to the terminal device 10 of the user.

The information processing apparatus 100 may provide information indicating the estimation result of the user's stage. The information processing apparatus 100 may transmit information indicating the estimation result of the stage of the user to the terminal device 10 of the user. The information processing apparatus 100 may transmit information indicating the estimation result of the user's emotion and the estimation result of the stage of the user to the terminal device 10 of the user.

The information processing apparatus 100 may provide information indicating a plurality of emotions ranked according to the score of each emotion. For example, the information processing apparatus 100 uses an emotion estimation model that outputs a score for each of a plurality of emotions, and ranks the estimated emotions ranked in descending order of the score output by the emotion estimation model to which the user's information is input. Listing information may be provided to the user. For example, the information processing device 100 may transmit list information of a plurality of emotions arranged in descending order of score to the terminal device 10 used by the user.

The information processing device 100 may provide information indicating a plurality of stages in which rankings are determined according to the scores of each stage. For example, the information processing apparatus 100 uses a stage estimation model that outputs a score for each of a plurality of stages, and uses the estimation stages ranked in descending order of the score output by the stage estimation model to which the user's information is input. Listing information may be provided to the user. For example, the information processing apparatus 100 may transmit, to the terminal device 10 used by the user, a plurality of levels of list information arranged in descending order of score.

The information processing apparatus 100 may provide information indicating a plurality of contents ranked according to the score of each content. For example, the information processing apparatus 100 uses a content determination model that outputs a score for each of a plurality of pieces of content, and uses a list of content ranked in descending order of the score output by the content estimation model to which user information is input. Information may be provided to the user. For example, the information processing apparatus 100 may transmit list information of a plurality of pieces of content arranged in descending order of score to the terminal device 10 used by the user.
