[0010] Embodiments of the present application will be described below with reference to the accompanying drawings. In the following description, the same parts are designated with the same reference numerals. They also have the same names and functions. Therefore, detailed description thereof will not be repeated, but the previous description will be referred to. <Embodiment 1> <Overall structure of network system 1> First, the overall structure of the network system 1 according to the present embodiment will be described with reference to Figure 1 The network system 1 according to the present embodiment mainly includes a server 100 for providing an SNS, and a plurality of communication terminals 300 each used by a user who utilizes the SNS. The communication terminal 300 is realized by a smartphone, a tablet, a personal computer, or the like, and is capable of communicating with the server 100 via the Internet, a carrier network, or the like. <Outline of operation of network system 1> Next, an outline of the operation of the network system 1 according to the present embodiment will be described.

[0011] First, as a premise, among users who utilize the SNS, there are users who post a large number of aggressive posts (negative posts) that have a high possibility of damaging the feelings of the other party (negative users). Also, normal users (neutral users), and users who post a large number of positive posts (positive users) are often emotionally damaged by slander, defamation, and other negative posts directed at themselves.

[0012] Therefore, in the present embodiment, with reference to Figure 2 , the server 100 analyzes the content of the post each time a user posts a post, and determines whether the post is positive, neutral, or negative. The server 100 calculates and holds the positive post ratio, the neutral post ratio, and the negative post ratio in advance for each user who posts a post.

[0013] Also, with reference to Figure 3 , the server 100 does not display the posts of users who have a high negative post ratio when a user who is a viewer utilizes the SNS. In other words, as shown in Figure 4 , in the case where a positive user posts a negative post, the post is displayed, and in the case where a negative user posts a negative post, the post is not displayed.

[0014] Thus, it is possible to reduce the possibility that a user who utilizes the SNS is emotionally damaged or causes mental abnormalities.

[0015] Hereinafter, the detailed structure of the network system 1 for realizing such a function will be described.

[0016] <Structure of server> First, one mode of the structure of the server 100 that constitutes the network system 1 according to the present embodiment will be described. Reference is made toFigure 5 The server 100 includes a CPU (Central Processing Unit) 110, a memory 120, an operation section 140, and a communication interface 160 as main components.

[0017] The CPU 110 controls the parts of the server 100 by executing a program stored in the memory 120. For example, the CPU 110 executes a program stored in the memory 120, and performs various processes described later by referring to various data.

[0018] The memory 120 can be realized by various RAMs (Random Access Memories), various ROMs (Read Only Memories), and the like, can be a product included in the server 100, can be a product attached to and detached from various interfaces of the server 100, and can be a recording medium of another device accessible from the server 100. The memory 120 stores a program executed by the CPU 110, data generated by the CPU 110 executing the program, various input data, other databases used in the service according to the present embodiment, and the like. For example, in the present service, the memory 120 stores user data 121. Referring to Figure 6 The user data 121 stores, for each user, a user ID, a user name, a total post number, a positive post number, a positive post ratio, a negative post number, a negative post ratio, a display restriction ratio, and the like.

[0019] In addition, the display restriction ratio is a value as an object of judgment that judges whether or not to display a post of another user (a second user) who is a poster as a user (a first user) who is a viewer. In a case where the negative post ratio of the second user exceeds the value of the display restriction ratio of the first user, the post of the second user is not displayed to the first user. In other words, the CPU 110 does not display the post of the second user in the display screen of the SNS of the first user in a case where the negative post ratio of the second user exceeds the display restriction ratio of the first user.

[0020] In the present embodiment, the CPU 110 registers or updates the display restriction ratio corresponding to the user of the communication terminal 300 when the display restriction ratio is designated from the communication terminal 300 through the communication interface 160. In addition, as an initial value at the time of service registration, it can be a form where no display restriction is applied, can be set to 100%, or can be set to 50% or other values.

[0021] Returning to Figure 5 The operation section 140 receives a command of a manager or the like of the service, and inputs the command to the CPU 110.

[0022] The communication interface 160 transmits data from the CPU 110 to the communication terminal 300 or other devices, etc. via the Internet, carrier wave network, router, etc. Conversely, the communication interface 160 receives data from these devices via the Internet, carrier wave network, router, etc. and hands over to the CPU 110 or stores in the memory 120.

[0023] <Information processing method of server> Next, the information processing at the time of receiving a post in the server 100 according to the present embodiment will be described with reference to Figure 7 to the CPU 110 of the server 100 according to the program of the memory 120 performs the following processing.

[0024] First, the CPU 110 receives a new post from the communication terminal 300 via the communication interface 160 (step S112). The post can be a comment on a video, a photo, a report, etc. or a comment or a reply to the comment. The CPU 110 stores the received text data in the memory 120 together with the user ID and the reception date and time (step S114).

[0025] The CPU 110 analyzes the received post by using AI or by using a server for natural language processing (step S116).

[0026] The CPU 110 judges whether the post this time is positive, negative, or neutral by the analysis (step S118). For example, the CPU 110 extracts a feature amount based on context from the data of the post or judges which emotion (positive, negative, neutral) these feature amounts represent using a machine learning model. In addition, the method of analyzing the content of the post and confirming the emotion is not limited.

[0027] The CPU 110 updates the user data 121 of the poster this time based on the judgment result (step S120). For example, the CPU 110 adds 1 to the total number of posts of the user ID of the poster, adds 1 to the number of positive posts or the number of negative posts according to the judgment result, and calculates and updates the positive post ratio or the negative post ratio.

[0028] Next, the information processing at the time of providing a post display screen in the server 100 according to the present embodiment will be described with reference to Figure 8 to the CPU 110 of the server 100 according to the program of the memory 120 performs the following processing.

[0029] First, the CPU 110 receives a request for a web page of an SNS from the communication terminal 300 via the communication interface 160 (step S132).

[0030] The CPU 110 retrieves news or posts having high relevance to the user of the communication terminal 300 based on the user's browsing history or other attributes (step S134).

[0031] The CPU 110 refers to the user data 121 to read out the display limit ratio of the user (step S136).

[0032] The CPU 110 removes posts by users whose negative post ratio exceeds the display limit ratio from the retrieved posts (step S138). Alternatively, the CPU 110 extracts only posts by users whose negative post ratio is less than the display limit ratio from the retrieved posts (step S138).

[0033] The CPU 110 generates web page data of the SNS composed of the remaining posts (step S140).

[0034] The CPU 110 transmits the web page data to the user's communication terminal 300 via the communication interface 160 (step S142).

[0035] <Structure of Communication Terminal 300> Next, one mode of the structure of the communication terminal 300 used by the user will be described with reference to Figure 9 For example, the communication terminal 300 according to the present embodiment includes a CPU 310, a storage 320, a display 330, an operation section 340, a communication interface 360, a speaker 370, a microphone 380, and a camera 390 as main components.

[0036] The CPU 310 controls each section of the communication terminal 300 by executing various programs stored in the storage 320.

[0037] The storage 320 is implemented by various RAMs, various ROMs, and the like. The storage 320 stores application programs for various services, web pages downloaded from the Internet, data generated by execution of programs by the CPU 310, data received from the server 100, data input via the operation section 340, information of the communication terminal 300 itself or information of the user, and the like.

[0038] The display 330 displays images or texts based on data from the CPU 310. The operation section 340 is composed of a pointing device, a switch, and the like, and inputs various commands from the user to the CPU 310. In addition, the communication terminal 300 can have a touch panel 350 including the display 330 and the operation section 340.

[0039] The communication interface 360 transmits and receives data between the server 100 and other devices via the Internet, a carrier wave network, a router, and the like. For example, the CPU 310 exchanges various information such as WEB page data, text data, image data, sound data, and the like with the server 100 via the communication interface 360 according to a program of a WEB browser or other application.

[0040] The speaker 370 outputs various sounds based on a signal from the CPU 310.

[0041] The microphone 380 receives sound and inputs sound data to the CPU 310. The CPU 310 receives a voice message from a user, which is not limited to the operation section 340, and transmits the voice message to the server 100.

[0042] The camera 390 photographs a moving image or a still image according to an instruction from the CPU 310, and inputs the image data to the CPU 310 or stores the image data in the storage 320.

[0043] In the present embodiment, the CPU 310 receives input of a post from a user who is a poster via the operation section 340. The CPU 310 transmits post data to the server 100 via the communication interface 360. Alternatively, the CPU 310 receives a command of page viewing from a user who is a viewer via the operation section 340. The CPU 310 receives data of an SNS page from the server 100 via the communication interface 360 and displays the data on the display 330.

[0044] <2nd Embodiment> In the above-described embodiment, the display limitation ratio is set for each user. However, the display limitation ratio can be determined for all users in advance. For example, 50% or the like.

[0045] Alternatively, the display limitation ratio can be automatically determined for each user according to a negative post ratio of own posts. For example, in step S136 of the above-described embodiment, the CPU 110 can read out the negative post ratio of a user who is a viewer from the user data 121 and set the negative post ratio as the display limitation ratio. That is, it is possible to not display a post from a user whose negative post is more than own negative post. Figure 8 <3rd Embodiment> Further, in the above-described embodiment, the display limitation ratio is set for each user. However, the display limitation ratio can be determined for all users in advance. For example, 50% or the like. Figure 8 ​In step S140, the CPU 110 can also include a number or an icon or the like of the display restriction ratio of the user who is the viewer in the page of the SNS for displaying the user. Thereby, the CPU 310 of the communication terminal 300 displays the page of the SNS on the display 330 while displaying the display restriction ratio set by the self at an arbitrary position of the screen. By displaying the display restriction ratio on the screen, the parent can recognize that the possibility of the child user viewing the negative post is low, and thus, can let the child use the SNS with peace of mind. Further, in the case where the user is an actor or a singer, an agent or a person in charge of an agency such as a talent agency can also recognize that the possibility of viewing the negative post is low. <4th Embodiment> Further, in the case where the user is an actor or a singer, an agent or a person in charge of an agency such as a talent agency can also recognize that the possibility of viewing the negative post is low. Figure 8 In step S140, the CPU 110 can also include a number or an icon or the like of the display restriction ratio of the user who is the viewer in the page of the SNS for displaying the user. Thereby, the CPU 310 of the communication terminal 300 displays the page of the SNS on the display 330 while displaying the display restriction ratio set by the self at an arbitrary position of the screen. By displaying the display restriction ratio on the screen, the parent can recognize that the possibility of the child user viewing the negative post is low, and thus, can let the child use the SNS with peace of mind. Further, in the case where the user is an actor or a singer, an agent or a person in charge of an agency such as a talent agency can also recognize that the possibility of viewing the negative post is low.

[0046] <5th Embodiment> Further, in the case where the user is an actor or a singer, an agent or a person in charge of an agency such as a talent agency can also recognize that the possibility of viewing the negative post is low. Figure 8 In step S140, the CPU 110 can also include a number or an icon or the like of the display restriction ratio of the user who is the viewer in the page of the SNS for displaying the user. Thereby, the CPU 310 of the communication terminal 300 displays the page of the SNS on the display 330 while displaying the display restriction ratio set by the self at an arbitrary position of the screen. By displaying the display restriction ratio on the screen, the parent can recognize that the possibility of the child user viewing the negative post is low, and thus, can let the child use the SNS with peace of mind. Further, in the case where the user is an actor or a singer, an agent or a person in charge of an agency such as a talent agency can also recognize that the possibility of viewing the negative post is low.

[0047] Further, in the case where the user is an actor or a singer, an agent or a person in charge of an agency such as a talent agency can also recognize that the possibility of viewing the negative post is low.

[0048] <6th Embodiment> Further, in the case where the user is an actor or a singer, an agent or a person in charge of an agency such as a talent agency can also recognize that the possibility of viewing the negative post is low. Figure 8 In step S140, the CPU 110 can also include a number or an icon or the like of the display restriction ratio of the user who is the viewer in the page of the SNS for displaying the user. Thereby, the CPU 310 of the communication terminal 300 displays the page of the SNS on the display 330 while displaying the display restriction ratio set by the self at an arbitrary position of the screen. By displaying the display restriction ratio on the screen, the parent can recognize that the possibility of the child user viewing the negative post is low, and thus, can let the child use the SNS with peace of mind. Further, in the case where the user is an actor or a singer, an agent or a person in charge of an agency such as a talent agency can also recognize that the possibility of viewing the negative post is low.

[0049] Thus, it is possible to reduce the adverse effect on the viewer when a user who has a small proportion of negative posts posts a negative post. In more detail, for a user who views the posts, it is possible to view the content of the posts after preparing oneself for the display of negative posts, and thus it is possible to reduce the impact. Further, the user who posts the posts can also recognize that his or her own posts are negative, and thus it is possible to modify or delete the content before the posts are viewed by a plurality of users.

[0050] In more detail, according to the structure of the fourth to sixth embodiments, it is possible to reduce the psychological impact of anonymization according to the "social feedback theory". The social feedback theory is the idea that people's behavior changes according to feedback from others. People are sensitive to how others perceive them and comment on them, and tend to modify their self-perception and behavior through the feedback of others. The user who posts a negative post receives feedback that his or her behavior is negatively evaluated because the behavior is marked as "negative". Thus, the user who values social evaluation is likely to avoid negative posts and change to actions that promote more positive communication. Further, other users also understand that negative posts are not accepted in society by observing the feedback, and the tendency to avoid similar posts is strengthened. This is also a part of the "social learning theory". The increase in aggressiveness in online (especially anonymous) web communication is described in many papers (online disinhibition effect). For example, for a user who posts a negative post, it is possible to expect improvement by providing feedback to the user. Figure 18 In the network system 1 according to the above-described embodiments, it is possible to hide the posts of a user who has many posts with these elements according to the tendency of the posts in general. <Seventh Embodiment> Further, with reference to Figure 10 , the CPU 110 preferably rearranges the posts of the users who have a small proportion of negative posts in order on the page of the SNS after removing the posts of the users who have a proportion of negative posts exceeding the display limit proportion from the retrieved posts (step S138). Then, the CPU 110 can also generate the page data of the SNS in which the posts are appropriately rearranged (step S140).

[0051] <Eighth Embodiment> Further, in Figure 8 and Figure 10In step S140, the CPU 110 can also post an advertisement on the page of the SNS according to the interest, preference, and attributes of the user who is the viewer. In particular, in the present embodiment, when the CPU 110 of the server 100 selects a user to send an advertisement to according to a request from an advertiser, it is preferable to give priority to sending an advertisement to the SNS page of a user who has a small proportion of negative posts. <9th Embodiment> In the above-described embodiments, the posts of the user are classified into three stages of positive, neutral, and negative. However, the present embodiment is not limited to this. For example, for each post, it can be further classified into a plurality of stages, or it can be classified into only two stages.

[0052] For example, as shown in Figure 11 the CPU 110 of the server 100 can classify the posts of the user into five stages of positive, slightly positive, neutral, slightly negative, and negative. Alternatively, the CPU 110 of the server 100 can classify the user who is the poster into five stages of a positive user, a slightly positive user, a neutral user, a slightly negative user, and a negative user. Furthermore, it can be a way of limiting the posts of a user who has a large proportion of slightly negative or negative posts to other users who are viewers.

[0053] <10th Embodiment> Further, as for the posts that are the source of the user data 121, only the amount of posts for a few months can be accumulated as effective posts. For example, for posts before more than half a year, it can not be reflected in the user data 121, or the weighting at the time of calculating the proportion of negative posts for posts within three months can be increased. <11th Embodiment> Part or all of the roles of each device of the network system 1 of the above-described embodiments can also be performed by other devices. For example, part or all of the roles of the server 100 of the above-described embodiments can also be assumed by other devices such as the communication terminal 300, or can be shared by a plurality of devices on the cloud.

[0054] For example, one server group can implement an SNS, one server group can perform language processing on the content of a post, and one server group can perform emotion analysis related to a post.

[0055] Alternatively, part of the program mounted on the server 100 can also be stored and executed in the communication terminal 300. In more detail, the CPU 110 of the server 100 extracts data of a plurality of posts corresponding to the interest, preference, attributes, and the like of the user who is the viewer and sends it to the communication terminal 300. In addition, the data of the post includes the content of the post, the name of the poster, and the proportion of negative posts of the poster.

[0056] On the other hand, the CPU 310 of the communication terminal 300 performs the following processing according to the application program for the SNS stored in the memory 320.

[0057] First, the CPU 310 of the communication terminal 300 judges whether it is a negative post at the time of posting by the user each time, according to the judgment of the CPU 310 or the judgment of the server 100. The CPU 310 updates the user data 121 of the memory 320 based on the judgment result. Further, the CPU 310 can also receive the setting of the display restriction ratio from the user via the operation section 340.

[0058] Then, as shown in Figure 12 , the data of a plurality of posts suitable for the interest, the preference, and the attribute of the user is received from the server 100 (step S232). The CPU 310 refers to the user data 121 and reads out the display restriction ratio of the user (step S236). The CPU 310 removes the post from the user whose negative post ratio exceeds the display restriction ratio from the posts received from the server 100 (step S238). Alternatively, the CPU 110 extracts only the post from the user whose negative post ratio is less than the display restriction ratio from the searched posts (step S238). The CPU 310 displays the screen of the SNS on the display 330 based on the data of the remaining posts (step S242).

[0059] <Supplement> Here, the judgment method of the negative or positive and the like related to the content of the post described above is supplemented. For example, the server 100 can also perform the sentiment analysis processing as shown in Figure 13 . In addition, the negative post is a post that gives stress (anger, disgust, disappointment) emotion to other users. Also, in the case of using a sentiment analysis model capable of subdividing negative situations, the emotion of "sadness, unease, loneliness" is a negative emotion, but the possibility of libel is high, so it is preferable that the CPU 110 does not judge it as a negative post.

[0060] <Other Application Examples> Further, the network system 1 of the above-described embodiment can be applied to the information processing of the SNS as an example, as shown in Figure 14 .

[0061] Alternatively, as an example, the network system 1 can also be applied to the post of the online game as shown in Figure 15 .

[0062] Alternatively, as an example, the network system 1 can also be applied to the post such as the news, the review, the comment of the video, and the like as shown in Figure 16 .

[0063] Alternatively, as an example, the network system 1 can also be applied to the post such as the news, the review, the comment of the video, and the like as shown in Figure 17The application is shown to posts on Twitter (registered trademark) and the like.

[0064] <Example of sentiment analysis with natural language processing model> Hereinafter, an example of sentiment analysis by AI analysis using a natural language processing model is shown. (Negative example 1) Post by A: "Found a new job, very happy!" Comment by B: "Will you quit that job soon anyway? From A's work performance, I think it won't last long." Sentiment analysis result: This comment contains aggressive and negative sentiment. B denies A's past work experience, questioning his ability and continuity.

[0065] (Negative example 2) Post by A: "Recently, I started paying attention to health and exercise every day." Comment by B: "Laughed to death, A actually said to pay attention to health. He always eats junk food." Sentiment analysis result: This comment also contains aggressive and negative sentiment. B negates A's new attempt with sarcastic words about A's past behavior.

[0066] (Positive example 1) Post by A: "I plan to go hiking in the mountains this weekend. I want to enjoy nature and restore my spirit!" Comment by B: "That's a great idea, A! Nature is the best relaxation. I look forward to your beautiful scenery photos!" Sentiment analysis result: This comment contains a positive, encouraging sentiment. B appreciates A's hiking plan, shares the joy, and expresses anticipation.

[0067] (Positive example 2) Post by A: "Made a handmade cake today. Although it's the first time, I think it's better than I imagined!" Comment by B: "Wow, A! That cake looks delicious! Your cooking taste and creativity always impress me." Sentiment analysis result: This review expresses a positive and appreciative sentiment. Little B appreciates little A's cooking ability, positively evaluates his attempt, and thanks for his effort.
