[1. Example of information provision processing]
FIG. 1 is a diagram showing an example of an information providing process according to an embodiment, and in this embodiment, an information providing method is executed by an information providing apparatus 1.

As shown in FIG. 1, the information providing device 1 is communicably connected to terminal devices 2 ₁ , 2 ₂ , ..., _{2 n used} by users U ₁ , U ₂ , ..., U n. and transmits and receives information to and from the terminal devices 2 ₁ , 2 ₂ , . . . , 2 _n . For example, n is an integer of 3 or more.

The information providing device 1 provides the terminal device 2 with online services including a chat service that processes posting of messages between the users U ₁ , U ₂ , . . . , _Un of the terminal device 2 in real time. Terminal device 2 ₁ is used by user U ₁ , terminal device 2 ₂ is used by user U 2 , and terminal device _{2 n} is used by user U _n .

An instant messenger application for chatting using the chat service provided by the information providing device 1 is installed on the terminal devices 2 ₁ , 2 ₂ , . . . , 2 _n . _In the following _, when each of the users U ₁ , _{U 2} , _. When shown without distinguishing them individually, they may be referred to as the terminal device 2.

The chat service provided by the information providing device 1 allows the users U to send timeline content, in which messages posted by the users U participating in the channels are arranged in a timeline format, for each of a plurality of different channels. Provided in real time to U.

A plurality of users U can participate in a channel, and the users U are provided with timeline content in which messages posted to the participating channels are arranged in a timeline format. A channel is provided corresponding to each user U, and other users U can participate in a certain user U's channel.

For example, user U ₂ and user _Un can participate in user U ₁ 's channel. Note that a channel may be provided for each user group composed of a plurality of users U. In the following description, it will be mainly assumed that a channel is provided corresponding to each user U.

Each user U can participate in the channel of another user U by requesting channel participation. In the following, the channel corresponding to user U and the channels of other users U in which user U participates may be collectively referred to as user U's participation channel or simply participation channel.

Users U ₂ to U _n operate terminal devices 2 ₂ to 2 _n to post to participating channels (steps S1 ₂ to S1 _n ). Posting to a participating channel is performed by transmitting a message including at least one of text information and image information to the information providing device 1.

The information providing device 1 performs a posting process to process messages posted by users U ₂ to U _n (step S2). In the posting process, for example, messages posted by users U ₂ to U _n are extracted for each participating channel of each user U ₂ to U _n , and timeline content in which the extracted messages are arranged in a timeline format is sent to the terminal device 2. ₂ to 2 _n .

Here, an example of the processing of the information providing device 1 and the terminal device 2 when the user _U1 uses the chat service provided by the information providing device 1 will be described. When using the chat service, the user _U1 operates the terminal device ₂₁ to cause the terminal device ₂₁ to transmit a content display request to the information providing device 1 (step S3).

When the information providing device 1 receives a content display request from the terminal device ₂₁ , it generates a plurality of timeline contents as content to be provided to the user _U1 (step S4). Then, the information providing device 1 sends the provided information to the terminal device 2 1 so that the plurality of generated timeline contents are arranged and displayed on the display unit (not shown) of the terminal device _{2 1 ,} thereby providing the provided information to the user U ₁ . (Step S5).

The terminal device ₂₁ displays a plurality of timeline contents side by side based on the provided information transmitted from the information providing device 1 (step S6). Each timeline content included in the provided information is timeline content for each extraction criterion in which messages extracted using different extraction criteria are arranged in a timeline format. Examples of the extraction criteria include a first extraction criterion, a second extraction criterion, and a third extraction criterion.

As a result, the user U ₁ can simultaneously check the timeline content for each extraction criterion in which messages extracted using different extraction criteria are arranged in a timeline format without changing the screen on the terminal device 2 ₁ . I can do it. Therefore, the information providing device 1 can improve convenience for the user _U1 .

A message that satisfies the first extraction criterion is, for example, a message posted to a channel in which user _U1 participates. In the example shown in FIG. 1, the first timeline content in which messages extracted based on the first extraction criterion are arranged in a timeline format is the timeline content of "user timeline", and "message A1 _k ", " Messages such as "message A2 _m " and "message A3 _p " are included.

“Message A1 _k ,” “message A2 _m ,” and “message A3 _p ” are, for example, messages posted to channel A, which is a channel in which user U ₁ participates. Thereby, the user _U1 can check the timeline content in which messages posted to participating channels are arranged in a timeline format. Note that when there are a plurality of channels in which the user _U1 participates, the first timeline content is timeline content in which messages posted to the plurality of participating channels are arranged in a timeline format.

Messages that satisfy the second extraction criteria are messages posted to all channels. In the example shown in FIG. 1, the second timeline content in which messages extracted using the second extraction criteria are arranged in a timeline format is the timeline content of the "Union Timeline", and the "Message A1 k", "Message A1 _k ", " Messages such as "Message B3 _q " and "Message C5 _h " are included. "Message A1 _k " is, for example, a message posted to channel A, "message B3 _q " is, for example, a message posted to channel B, and "message C5 _h " is, for example, a message posted to channel C. This is a posted message.

Thereby, the user _U1 can check the timeline content in which messages posted to channels including all channels including participating channels and non-participating channels are arranged in a timeline format. Note that the second extraction criterion does not need to include messages posted to channels in which user _U1 participates, and may include messages sampled randomly or based on a predetermined rule among messages posted to all channels. There may be.

A message that satisfies the third extraction criterion is a message posted to the channel by a "recommended user" who is another user U who recommends the user _U1 . In the example shown in FIG. 1, the third timeline content in which messages extracted using the third extraction criterion are arranged in a timeline format is the timeline content of "Recommended User", "Message C4 _g ", "Message Messages such as "B3 _q " and "Message B3 _q-1 " are included.

"Message C4 _g " is, for example, a message posted by user U _n to channel C, and "message B3 _q " and "message B3 _q-1 " are messages posted to channel B by user U ₂ , for example. be. In this case, the recommended users are users U ₂ , _Un , etc.

The recommended user is, for example, a user U whose attributes are similar to the user U ₁ , or another user U whose messages posted by the user U ₁ are similar or related in content. User U ₁ can obtain new information by checking the third timeline content and participating in channels of other users U who are interested, and can effectively utilize the chat service. can.

Here, each message included in the timeline content has corresponding information on the posting user (user U who posted the message), information on the posting channel, information on the posting date and time, a high rating button, a low rating button, and a pointing out button. This information is included for each message in one frame.

In the example shown in FIG. 1, the message C4 _g is "Today we have a study session in the morning." The message C4 _g includes the posting user "U _n ", the posting channel "Channel C", and the posting date and time "2021-9". -15 11:16:33'', a high evaluation button, a low evaluation button, and an indication button are associated with each other.

The high evaluation button is a button that is selected by a user U other than the posting user when they like the message C4 _g , and the low evaluation button is a button that is selected by a user U other than the posting user when they do not like the message C4 _g . button. Further, the pointing out button is a button selected by the user U other than the posting user when pointing out that the message _C4g is an inappropriate message. Selection of a button is performed, for example, by a click operation or a tap operation.

The information providing device 1 notifies the posting user of information indicating the number of times the high evaluation button, low evaluation button, and indication button have been selected. Thereby, the posting user, who is the user U who posted the message _C4g , can understand the evaluation and appropriateness of the posted message _C4g .

Furthermore, when the selection result of the pointing out button satisfies a preset condition, the information providing device 1 imposes a penalty on the posting user, which is the user U who posted the message for which the pointing out button was selected. For example, the information providing device 1 imposes a penalty on the inappropriate posting user, which is the user U who posted a message in which the number of times the indication button has been selected is greater than or equal to a preset threshold.

Penalties can be imposed, for example, by temporarily prohibiting a user who posted an inappropriate post from posting all messages, or by temporarily prohibiting a user who posted an inappropriate post from posting messages to participating channels other than the channel of the user who posted the inappropriate post. It will be done. Further, the penalty may be imposed by changing the UI (User Interface) for sending messages so that it takes more effort to post messages. Thereby, the information providing device 1 can reduce the possibility that the posting user will post an inappropriate message.

The estimation unit 42 estimates the context of each user U based on the detection information acquired by the acquisition unit 40. The context of the user U is the situation, environment, or intention of the user U, such as "I'm on a train for commuting", "I'm on a train on a business trip", "I'm having a meeting", " Examples include ``I am shopping at store A'' or ``I am taking a walk.''

The estimation unit 42 can estimate the user U's context using, for example, an estimation model generated by machine learning. The estimation model is a model that determines whether or not the context of the user U is the context specified by the estimation model.The estimation model is a model that determines whether the context of the user U is the context specified by the estimation model. Determine whether or not.

Note that the estimation model may be a model that inputs the detection information acquired by the acquisition unit 40 and outputs information indicating which of a plurality of contexts the context of the user U is. Furthermore, the estimation unit 42 may be configured to estimate the context of the user U from the detection information acquired by the acquisition unit 40 without using an estimation model.

Further, the estimating unit 42 may, for example, estimate the users U who are riding the same train, estimate the users U who are participating in the same conference, or estimate the users U who are developing the same development target. can be estimated.

[4.3.4. Extraction part 43]
The extraction unit 43 extracts messages or contents from the messages acquired by the acquisition unit 40 using different extraction criteria. For example, when a content display request is acquired by the acquisition unit 40, the extraction unit 43 extracts a message or content based on extraction criteria corresponding to the content ID included in the user information stored in the user information storage unit 30.

Examples of the extraction criteria include a first extraction criterion, a second extraction criterion, a third extraction criterion, a fourth extraction criterion, and a fifth extraction criterion. The first extraction criterion is an extraction criterion corresponding to the content ID "TLC1". The second extraction criterion is an extraction criterion corresponding to the content ID "TLC2". The third extraction criterion is an extraction criterion corresponding to the content ID "TLC3". The fourth extraction criterion is an extraction criterion corresponding to the content ID "TLC4". The fifth extraction criterion is an extraction criterion corresponding to the content ID "TLC5".

A message that satisfies the first extraction criterion is a message posted to a channel in which the destination user participates.

A message that satisfies the second extraction criterion is a message posted to each of all channels or a message posted to each of a plurality of preset channels among all channels. The preset message is, for example, a message posted to a channel that is permitted to be used as a message that satisfies the second extraction criterion.

A message that satisfies the third extraction criterion is a message posted on a channel by a recommended user determined by the determination unit 41. The extraction unit 43 can also extract a message according to the context of the destination user from among the messages that satisfy the third extraction criterion. For example, the extraction unit 43 can also extract messages that satisfy the third extraction criterion, excluding messages of other users U whose context is a specific context. Further, the extraction unit 43 can extract, for example, messages posted by recommended users excluding messages posted when the context of the destination user is a specific context.

Content that satisfies the fourth extraction criterion is content that has been posted to a service other than a chat service and that satisfies preset attributes. For example, when the content is news content, the attributes of the content include economic news, international news, domestic news, entertainment news, sports news, and the like. Note that the content is not limited to news content, and may be content such as gourmet information, real estate information, and used car information. Furthermore, the content that satisfies the fourth extraction criterion may be, for example, content that shows user U's owned assets or content that shows deposits and withdrawals shown in a household account book.

A message that satisfies the fifth extraction criterion is a message that corresponds to the context of the destination user. The message according to the context of the destination user is, for example, a message posted by another user U having the same context as the context of the destination user.

For example, when the destination user is on the move, the extraction unit 43 extracts a message posted by another user U who is presumed to be on the move, as a message that satisfies the fifth extraction criterion. For example, when the destination user is on a train, the extraction unit 43 extracts a message posted by another user U who is presumed to be on the same train as the destination user. Extract messages that meet the criteria.

Furthermore, the message according to the context of the destination user may be, for example, a message posted by another user U whose context is different from the context of the destination user. For example, when the destination user is having a meeting, the extraction unit 43 can also extract messages posted by other users U who are on the move.

Note that the extraction criteria are not limited to the first to fifth extraction criteria described above, and various criteria can be set. For example, the extraction criteria may be extraction criteria for extracting messages related to a specific topic, or may be extraction criteria for extracting messages from user U belonging to a specific department. Further, the extraction criterion may be an extraction criterion for extracting randomly selected messages. Note that the extraction criteria can also be changed for each user U.

[4.3.5. Providing Department 44]
The providing unit 44 provides the user U with provided information that causes the display unit 11 of the terminal device 2 to display timeline content for each extraction criterion in which the messages for each extraction criterion extracted by the extraction unit 43 are arranged in a timeline format. provide. The provided information is provided to the user U by transmitting it to the terminal device 2 via the communication unit 20 and the communication network 3.

For example, when the extracting unit 43 extracts messages based on the first extraction standard, the second extraction standard, and the third extraction standard, the providing unit 44 provides the first timeline content, the second timeline content, The user U is provided with information that is displayed on the display unit 11 of the terminal device 2 side by side with the third timeline content.

The processing unit 15 of the terminal device 2 receives the provided information from the information providing device 1 via the communication network 3, and based on the received provided information, creates the first timeline content, the second timeline content, The third timeline content is displayed on the display unit 11 side by side.

FIG. 8 is a diagram illustrating an example of first timeline content, second timeline content, and third timeline content that are displayed side by side on the display unit 11 of the terminal device 2 according to the embodiment. As shown in FIG. 8, a first timeline content 61, a second timeline content 62, and a third timeline content 63 are displayed side by side on the display unit 11 of the terminal device 2.

The first timeline content 61 is a timeline content in which messages posted to a participating channel of a user U who is a destination of provided information are arranged in a timeline format. This allows the destination user to check timeline content in which messages posted to participating channels are arranged in a timeline format.

The second timeline content 62 is timeline content in which all messages posted to each of a plurality of channels are arranged in a timeline format. Thereby, the destination user can check messages posted to channels other than the participating channel while checking the first timeline content 61 without changing the screen of the terminal device 2.

The third timeline content 63 is timeline content in which messages of recommended users who are other users U who have posted to channels other than the participating channel of the destination user and are determined by the determination unit 41 are arranged in a timeline format. It is. Thereby, the destination user can check the recommended user's message while checking the first timeline content 61 without changing the screen of the terminal device 2. By participating in the channels of other users U who are interested, the destination user can obtain new information and effectively utilize the chat service.

Further, when the extracting unit 43 extracts the messages of the first extraction criterion, the fourth extraction criterion, and the fifth extraction criterion, the providing unit 44 extracts the first timeline content 61 and the fourth timeline content. , and the fifth timeline content to be displayed on the display unit 11 of the terminal device 2 to the user U.

The fourth timeline content is a timeline content in which content that has been posted to a service other than a chat service and that satisfies preset attributes is arranged in a timeline format. As a result, the destination user can easily check the timeline content of the content posted on services other than the chat service while checking the timeline content of the channel without changing the screen of the terminal device 2. can.

The fifth timeline content is a timeline content in which messages according to the context of the destination user are arranged in a timeline format. Thereby, the provision destination user can easily check the message according to the context while checking the first timeline content 61 without changing the screen of the terminal device 2.

Each message included in the timeline content is associated with information about the posting user (user U who posted the message), posting channel information, posting date and time information, a high rating button, a low rating button, and a pointing button. This information is included for each message within one frame.

FIG. 9 is a diagram illustrating an example of a message area including messages included in timeline content according to the embodiment. As shown in FIG. 9, the message area 70 included in the timeline content includes a message 71, posting user information 72, posting channel information 73, posting date and time information 74, a high evaluation button 75, a low evaluation button 76, and an indication button 77.

The posting user information 72 is information for specifying the posting user who is the user U who posted the message 71, and the posting channel information 73 is information for specifying the channel on which the message 71 was posted. The posting date and time information 74 is information indicating the date and time when the message 71 was posted.

The high evaluation button 75 is a button selected by a user U other than the posting user when the message 71 is liked. The low evaluation button 76 is a button selected by a user U other than the posting user when the message 71 is not liked. The pointing out button 77 is a button selected by a user U other than the posting user when pointing out that the message 71 is an inappropriate message. Selection of a button is performed, for example, by a click operation or a tap operation.

A user U different from the posting user can evaluate or point out the message 71 by selecting the high evaluation button 75, the low evaluation button 76, or the pointing out button 77. Note that the message area 70 may include information on the number of times each button is selected at a position corresponding to each of the high evaluation button 75, low evaluation button 76, and indication button 77.

The providing unit 44 aggregates the number of times each button, such as the high evaluation button 75, low evaluation button 76, and pointing out button 77, is selected for each message or for each posting user, and provides selection information indicating the aggregated results. The selection information is provided to the posting user by transmitting it to the posting user's terminal device 2.

Further, the providing unit 44 can also provide information indicating that the pointing out button 77 has been selected to the posting user only when the selection result of the pointing out button 77 satisfies preset conditions. The preset condition is, for example, the ratio of the display number, which is the number of other users U who have displayed the message posted by the posting user, and the selection number, which is the number of selections of the pointing button 77 of the message, is a threshold value. The above condition is a condition for each message or each posting user.

Note that the preset condition may be that the number of selections is greater than or equal to a threshold, or may be any other condition. For example, if the condition is for each posting user, the condition is that the number of times the pointing out button 77 of messages posted by the posting user is selected divided by the number of messages posted by the posting user is greater than or equal to the threshold. It's okay.

Further, the providing unit 44 includes a message whose selection result of the indication button 77 satisfies preset conditions or a message of a posting user who posted such a message and which is displayed in the timeline content of another user U. Message area 70 can be highlighted. Thereby, the information providing device 1 can increase the degree of attention of other users U to the message for which the pointing out button 77 has been selected or the message of the posting user who posted such a message. Note that the highlighting is performed by, for example, making the text of the message thicker, changing the color of the message, making the text of the message larger, or blinking the message area 70.

[4.3.6. Penalty execution unit 45]
If the selection result of the indication button 77 satisfies a preset penalty condition, the penalty execution unit 45 applies a penalty to the inappropriate posting user who posted the message for which the indication button 77 was selected.

The penalty condition is, for example, the ratio of the display number, which is the number of other users U who have displayed the message posted by the inappropriate posting user, and the selection number, which is the number of times when the pointing button 77 of such message was selected. The condition is that the appropriate button selection ratio is equal to or higher than a threshold value, and this condition is a condition for each message or each posting user. Further, the penalty condition may be a condition that the number of selected pointing buttons, which is the number of selected pointing buttons 77, is greater than or equal to a threshold value, and such a condition is a condition for each message or each posting user.

Note that the penalty conditions are not limited to the example described above. For example, if the penalty condition is for each inappropriate posting user, the value obtained by dividing the number of times the pointing out button 77 of messages posted by the inappropriate posting user is selected by the number of messages posted by the posting user is: The condition may be that it is equal to or greater than a threshold value.

The penalty execution unit 45 can impose a penalty on the inappropriate posting user, for example, by changing the display mode of the timeline content provided to the inappropriate posting user. For example, the penalty execution unit 45 may make the update cycle of the timeline content provided to the inappropriate posting user longer than usual, or make the display size of the timeline content provided to the inappropriate posting user smaller than usual. You can do it. Normal is the state before a penalty is applied to the posting user.

Further, the penalty execution unit 45 makes the message area 70 containing the message posted by the inappropriate posting user and displayed in the timeline content of other users U less conspicuous or less visible than usual. It is also possible to impose penalties on users who post inappropriate posts. Making the message area 70 less noticeable or less visible includes, for example, making the message area 70 lighter in color or making the message area 70 smaller.

Further, the penalty execution unit 45 imposes a penalty on the inappropriate posting user by restricting posting of messages by the inappropriate posting user and restricting provision of timeline content to the inappropriate posting user. You can also do that. For example, the penalty execution unit 45 may temporarily prohibit the inappropriate posting user from posting all messages, or temporarily prohibit the posting of messages to participating channels other than the inappropriate posting user's channel. do.

Note that the penalty execution unit 45 can increase the intensity of the penalty as the degree of inappropriateness of the inappropriate posting user increases. For example, the inappropriateness level of the inappropriate posting user increases as the inappropriate button selection rate or the number of indication button selections increases.

For example, if the strength of the penalty is low, the penalty execution unit 45 changes the UI that displays multiple timeline contents side by side, and if the strength of the penalty is low, it restricts posting of messages by inappropriate posting users, etc. can be processed. Further, the penalty execution unit 45 can also, for example, lengthen the period during which inappropriate posting users are prohibited from posting messages as the intensity of the penalty increases.
