3 is a block diagram illustrating an example of components that may be included in a processor of an electronic device according to an embodiment of the present invention, and FIG. 4 is a method that the electronic device according to an embodiment of the present invention may perform. It is a flow chart showing an example of

An access control system implemented by a computer may be configured in the electronic device 110 according to the present embodiment. As an example, the access control system may be implemented in the form of a program that operates independently, or may be configured in the form of an in-app of a specific application to operate on the specific application, and in some cases, the server ( 150), it is possible to provide a function to control user access through conversation analysis in a messenger service.

An access control system implemented in the electronic device 110 based on a command provided by an application installed in the electronic device 110 may perform an access control method. In order to perform the access control method according to FIG. 4, the processor 212 of the electronic device 110, as shown in FIG. An access control unit 330 may be included. Depending on embodiments, components of the processor 212 may be selectively included in or excluded from the processor 212 . Also, components of the processor 212 may be separated or merged to express functions of the processor 212 according to embodiments.

The processor 212 and components of the processor 212 may control the electronic device 110 to perform steps S410 to S430 included in the access control method of FIG. 4 . For example, the processor 212 and components of the processor 212 may be implemented to execute instructions according to an operating system code and at least one program code included in the memory 211 .

Here, components of the processor 212 are performed by the processor 212 according to commands provided by program codes stored in the electronic device 110 (for example, commands provided by applications running in the electronic device 110). may be representations of different functions of the processor 212 being For example, the publicity level determining unit 310 may be used as a functional expression of the processor 212 that controls the electronic device 110 according to the above command to determine the publicity level of the electronic device 110 for the chat room. there is.

The processor 212 may read necessary commands from the memory 211 loaded with commands related to controlling the electronic device 110 . In this case, the read command may include a command for controlling the processor 212 to execute steps S410 to S430 to be described later.

In step S410, the publicity level determination unit 310 analyzes conversation contents exchanged between the user of the electronic device 110 and the conversation partner for each conversation partner registered in the messenger to determine the publicity level of the conversation partner. For example, the achievement level determination unit 310 may extract honorifics from a conversation that the user has with a conversation partner and calculate an achievement score according to the use of honorifics. At this time, the achievement level determination unit 310 may calculate the achievement score using the frequency of use of honorific words compared to all conversations, the importance of honorific words in conversation, and the like. In addition, the achievement level determination unit 310 may calculate the achievement score by additionally using the length of conversation sentences, the frequency of using slang or jargon, and the completeness of sentences. Accordingly, the publicity degree determining unit 310 may determine the publicity level indicating the public relationship with the conversation partner by analyzing the conversation contents between the user and the conversation partner.

In step S420, the achievement level determination unit 310 may determine the achievement level of each chat room in the messenger based on the achievement level of each conversation partner. A chat room may include at least one chat partner, and at this time, the publicity level determination unit 310 may calculate a public score for a corresponding chat room by using a public score of an individual chat partner included in each chat room. .

In step S430, the access control unit 330 may control the user's access to the chat room based on the achievement level of each chat room in the messenger. In this case, the access control unit 330 may control sorting or displaying a chat room list of a messenger, locking an input of a chat room, displaying a screen, displaying a notification, correcting a transmission phrase, recommending contents, and the like, based on the achievement score for each chat room.

Furthermore, the topic extractor 320 may analyze conversation contents included in each chat room for each chat room to extract a core topic of the corresponding chat room. The topic extractor 320 may calculate the importance of words in the conversation content based on the frequency of words appearing in the conversation content of the chat room, and may find at least one key keyword using the word importance. Accordingly, the access control unit 330 can also control the input of the chat room based on the core topic extracted from the chat room.

Specific embodiments of the process of calculating the achievement score for each conversation partner (S410) are as follows.

The following data can be utilized for each conversation partner to calculate the public score.

(1) Frequency of honorifics and their importance in sentences

The achievement degree determination unit 310 may determine the degree of achievement by analyzing how many honorifics are used in a conversation and how important the honorifics used are in a sentence.

In detail, the achievement level determination unit 310 may classify paragraphs and sentences from conversation contents exchanged between the user and the conversation partner through word analysis (tokenizer), and then divide phrases and words from each paragraph or sentence.

The achievement level determination unit 310 may extract individual morphemes from the divided phrases or words through morpheme analysis, part-of-speech analysis, and basic form analysis of natural language processing. For example, for 'I', individual morphemes can be extracted as 'I' (pronoun) + 'is' (article) or 'day' (verb, fly) + 'is' (tubular ending).

The achievement degree determination unit 310 may determine whether individual morphemes correspond to honorific words representing honorific titles or honorifics based on the honorific language corpus and honorific morphemes constructed as a dictionary database. For example, the public achievement level determination unit 310 may detect the honorific ending or the honorific noun in the part-of-speech analysis. Honorific titles are largely expressed through words (phrases), suffixes (or particles), preterm endings, and ending expressions. In Hangeul, 'Elder', 'He', and 'Jinji' are expressions of honor through vocabulary, and 'Nim' of 'Teacher' and 'Da', 'Gae', and 'Ke' of 'You' are suffixes or postpositions. The expression of honorifics using 'Jinji' is the expression of honorific titles through vocabulary, and '~si' and '~ssi' are expressions of honorifics through endings. In English, 'Sir', 'madam', etc. used at the end of a sentence, 'Mr', 'Ms', 'Dear', etc. used instead of a name, and interrogative modal verbs would, could, etc. For example, 'appreciate', 'be obliged to', etc. compared to 'Thank', and 'let me know' compared to 'tell me' can be more formal honorific expressions.

The publicity level determination unit 310 detects honorific words in conversation contents using attributes indicating the level of words themselves provided by the dictionary database, as well as based on big data, for example, diplomatic documents, corporate announcements, It is possible to analyze the characteristics related to honorific speech by collecting documents, such as business documents, in which formal honorific expressions are mainly used, and based on the results of big data analysis, honorific words in conversations can be extracted.

The achievement degree determination unit 310 may analyze the frequency of use of the honorific language in preparation for the entire conversation content and calculate the word importance of the corresponding honorific language within the conversation content based on the frequency of use of the honorific language. For example, the achievement level determination unit 310 models a Term Frequency-Inverse Document Frequency (TF-IDF) for calculating the importance of words in a document based on frequency and words existing in front and back in a document to determine the relationship between words. Using a probabilistic language model (N-gram) to identify the , the importance of honorific words in conversations can be calculated.

(2) Percentage of phrases

The publicity level determination unit 310 may analyze conversation contents in phrase units, classify polite phrases, and calculate a proportion of honorific phrases in conversation. For example, the sentence 'This solution is really not suitable here' can be divided into phrase units 'this solution', 'really', and 'not suitable'. The achievement level determination unit 310 may select an honorific phrase including an honorific phrase from among phrase units in a sentence and calculate a ratio occupied by the honorific phrase with respect to all phrases of the sentence.

(3) Sentence Length Ratio

The achievement level determination unit 310 may calculate the average length of sentences from conversation contents exchanged with the conversation partner, and may calculate a sentence length ratio to the average of all conversation partners. Considering that the shorter the length of the sentence, the higher the probability of a private relationship, and the longer the length of the sentence, the higher the probability of a public relationship, the sentence length ratio can be used to calculate the public score.

(4) Rate of use of non-standard language

The publicity level determination unit 310 may use a dictionary database including non-standard words such as abbreviations, profane words, slang, dialects, buzzwords, etc. to calculate the frequency of using non-standard words in the conversation contents exchanged with the conversation partners, and The ratio of non-standard language use can be calculated. Considering that the probability of a public relationship is high as the frequency of using non-standard words in conversation sentences is low, the ratio of using non-standard words can be used to calculate the public score.

(5) Sentence completeness rate

The publicity level determination unit 310 may calculate the frequency of use of sentences having a complete structure in conversation contents exchanged with the conversation partner, and may calculate a sentence completeness ratio compared to an average of all conversation partners. For example, the sentence structure of Hangeul is based on the arrangement order of subject-(object)-predicate type, and the relationship with the conversation partner can be inferred by figuring out how much a sentence with a complete structure occupies in the entire conversation. Considering that the sentence structure tends to be destroyed as the relationship becomes more private, the sentence completion rate can be used to calculate the public score.

(6) Contact group bonus points

The achievement level determination unit 310 may analyze the name of a contact group to which the conversation partner belongs among the contact groups in the contact application of the electronic device 110 to assign a weight representing the achievement level. For the contact group name created in the contact application of the electronic device 110, a weight value according to a degree of publicity may be predefined. For example, if a contact group in which a contact is registered has a name indicating an official relationship such as a company or a business partner, additional points may be given to the contact group.

(7) Near-distance points

The achievement level determination unit 310 may assign a weight representing the achievement level to a conversation partner located near the user in a preset public place by using short-range communication of the electronic device 110 . For example, the achievement level determination unit 310 may give a short distance bonus point to a conversation partner who has stayed around the user for a long time at a company set by the user.

(8) Content bonus points

The achievement degree determination unit 310 may assign a weight indicating the degree of achievement to the conversation partner based on the type of content exchanged with the conversation partner or the result of image object recognition. A text tag dictionary in which the degree of achievement is defined can be built in advance, and based on this dictionary, after recognizing an object in a photo or video image exchanged with a conversation partner, a text tag of the recognized object can be used to determine the achievement corresponding to the tag. Additional points may be given according to the degree of content. In addition, among the contents exchanged with the conversation partner, the higher the proportion of a specific type of content, for example, a screen shot or a document, the higher the likelihood of an official relationship. Thus, a content bonus point may be given to the conversation partner according to the proportion of the corresponding content.

The achievement level determination unit 310 may calculate the first achievement score for the conversation partner using (1) the frequency of honorific words and the importance in sentences among the above data.

The first achievement score can be defined as in Equation 1.

[Equation 1]

Here, 1 _st Score _x is the primary public score for conversation partner x, s is the score given to each morpheme corresponding to honorific, w is a weight assigned according to the importance of each morpheme corresponding to honorific, and N is the overall conversation means number.

Furthermore, the achievement level determination unit 310 is (2) a phrase ratio, (3) a sentence length ratio, (4) a non-standard language usage ratio, (5) a sentence completeness ratio, (6) a contact group bonus point, and (7) a short distance A final public score for the conversation partner may be calculated by additionally using at least one of an additional point and (8) a content point.

For example, the final achievement score may be defined as Equation 2.

[Equation 2]

Here, Score _x is the final achievement score for the interlocutor x, R _p is the percentage of phrases, R _l is the percentage of sentence length, R _s is the percentage of non-standard words, R _c is the percentage of sentence completeness, w _c is the contact group bonus, w _p denotes a short distance bonus point, and w _i denotes a content bonus point.

In addition, the achievement level determination unit 310 may calculate the reliability of the achievement score of the conversation partner using the number of conversations and the conversation frequency rate, and may calculate the reliability through Equation 3, for example.

[Equation 3]

Here, Confience _n means the reliability of the public score of conversation partner n, and can be calculated as the ratio of the average number of conversations exchanged with conversation partner n per day to the average number of conversations exchanged with all conversation partners per day. there is.

와 같다.The minimum number of conversations required to calculate the reliability of the achievement score of the conversation partner can be set, and the reliability function according to the minimum number of conversations is

Same as

A public score of a conversation partner whose reliability is less than a threshold may be invalidated, and a public score of a conversation partner whose reliability is guaranteed to be higher than or equal to the threshold may be used as valid data to calculate a public score for each chat room. As another example, it may be used to calculate the achievement score of each chat room by assigning a differential weight to the achievement score of the conversation partner according to the degree of reliability.

In the above, the process of calculating the public score based on the contents of conversation has been described, and the method of calculating the public score of a conversation partner without conversation contents with the user is as follows.

The publicity level determination unit 310 may obtain a social graph related to the user from the server 150 and predict a public score for the conversation partner through relationship analysis. To this end, the publicity degree determination unit 310 obtains the social graph and conversation frequency between people formed in the messenger service from the server 150, and then connects the relationship between people with a line and uses the conversation frequency as a weight of the friend. A network graph of relationships can be formed. At this time, the achievement level determination unit 310 clusters the friend relationships in the network graph, and from the achievement scores of the friends included in the cluster targeting the cluster to which the conversation partner who has no conversation with the user belongs, for example, the achievement level within the cluster The average or median of the achievement scores of friends can be estimated as the achievement score for the conversation partner.

Similarly, in the case of a conversation partner who does not have a conversation with the user, at least one of (6) a contact group bonus point and (7) a proximity point bonus among the above data may be additionally reflected in the achievement score.

Specific embodiments of the process of calculating the achievement score for each chat room (S420) are as follows.

When the achievement score calculation is completed for each conversation partner registered in the messenger, the achievement level determination unit 310 may calculate the achievement score of the chat room by using the achievement score of the conversation partner included in each chat room.

As an example, the achievement score of a chat room may be defined as in Equation 4.

[Equation 4]

와 같으며, CI_i는 대화 상대 i가 대화를 시작한 횟수를 의미한다.Here, Score _x is the public score for chat room x, S _i is the public score for chat room i, R _i is the ratio of the number of conversations with chat room i, and N _x is the number of people included in chat room x. R _i is

, and CI _i means the number of times conversation partner i started a conversation.

The specific process of extracting core topics for each chat room is as follows.

The subject extractor 320 may extract text and images from conversation contents exchanged in the chat room. At this time, the subject extractor 320 may extract text and images from the clipboard used in the chat room or prefetch a URL shared through the chat room to extract text and images from the web page content of the corresponding URL. there is.

The topic extractor 320 can divide paragraphs and sentences from conversation contents through word analysis, then divide phrases and words from each paragraph or sentence, and individual Morphemes can be extracted, and in the case of images, text tags of objects included in images can be extracted through image object recognition.

The topic extractor 320 may select at least one core topic from individual morphemes extracted from conversation content through TF-IDF and a probabilistic language model. The topic extractor 320 uses a probabilistic language model to determine the relationship between TF-IDF and adjacent words for calculating the importance of words in a document based on frequency, and uses a key topic word with high importance among frequently appearing nouns or pronouns. can be found.

Accordingly, the topic extractor 320 may extract a core topic related to a corresponding chat room by analyzing the conversation contents of each chat room. Key topics for each chat room can be used to control user access to the chat room.

In the above, it has been described that the electronic device 110 performs the process of determining the degree of achievement (S410 to S420) and the process of extracting the core subject based on the command provided by the application installed in the electronic device 110, but is not limited thereto. Depending on the example, the server 150 may directly perform the above process on the side of the server 150 in conjunction with an application installed in the electronic device 110 .

Specifically, in order for the server 150 to perform some of the access control methods according to FIG. 4 , the processor 222 of the server 150 may include a publicity level determination unit and a subject extraction unit. Depending on embodiments, components of the processor 222 may be selectively included in or excluded from the processor 222 . Also, components of the processor 222 may be separated or merged to express functions of the processor 222 according to embodiments.

The processor 222 and components of the processor 222 may control the server 150 to perform the process of determining the degree of achievement (S410 to S420) and the process of extracting the core subject. For example, the processor 222 and components of the processor 222 may be implemented to execute instructions according to an operating system code and at least one program code included in the memory 221 .

The achievement level determination unit and the subject extraction unit included in the processor 222 of the server 150 are the same as or correspond to the achievement level determination unit 310 and the subject extraction unit 320 described with reference to FIG. Since (S410 to S420) and the core subject extraction process are performed, a detailed description of the components of the processor 222 will be omitted.

In other words, it is also possible that the achievement score calculation or core subject extraction is performed in the electronic device 110 as well as in the server 150 to provide the result value to the electronic device 110 . When calculation of public scores or extraction of key topics is performed in the electronic device 110, information that cannot be obtained in the electronic device 110 may be requested and brought to the server 150 in some cases to perform corresponding processes. As another example, the electronic device 110 may calculate a public score for each conversation partner in the messenger and upload it to the server 150, and the server 150 maintains a public score for each conversation partner for each user using the messenger service. While doing so, when a request is made, a public score for each conversation partner having a friend relationship with a specific user may be provided to the corresponding electronic device.

Specific embodiments of the process of controlling user access to the chat room (S430) are as follows.

For example, the access control unit 330 may automatically apply a lock setting to an input tool of a corresponding chat room based on the achievement score of each chat room when the achievement score is equal to or greater than a threshold value. Referring to FIG. 5 , when a chat room 500 with an achievement score equal to or higher than a threshold value is entered, an inactive window 510 for inactivating the input tool may be overlaid and displayed on an input tool including a conversation input window. An inactive window 510 may be overlaid on an input tool in the chat room 500 so that not only simple text input but also all inputs such as photos, videos, and emoticons (stickers) are disabled. In a state in which the chat room 500 is locked, in response to a user's unlock request, for example, when a user long-touches the inactive window 510 for a certain period of time, the inactive window 510 disappears and the use of the input tool is allowed.

As another example, the access control unit 330 may selectively set whether or not to lock input for each chat room according to user settings. At this time, among chat rooms of a messenger, a chat room having an achievement score equal to or higher than a threshold value is recommended as a chat room for setting input lock. can do.

As another example, as shown in FIG. 6 , when entering a chat room 500 with an achievement score equal to or higher than the threshold value, the access control unit 330 overlays and displays an inactive window 510 on an input tool in the chat room 500. At the same time, at least one guide information 611 of a phrase and an image representing an official relationship may be displayed on the inactive window 510 . By adding guide information 611 to the inactive window 510 of the chat room 500, information on public relationships can be provided. The guidance information 611 may be set to a specific phrase or image desired by the user, and may be collectively set for all chat rooms in which an achievement score is greater than or equal to a threshold value, or may be set individually for each chat room. Depending on the case, the level of the chat room may be classified based on the achievement score, and at this time, it is also possible that the guide information 611 is set for each level.

As another example, the access control unit 330 may highlight a phrase entered in the chat room or automatically correct the phrase when the achievement score is greater than or equal to a threshold value based on the achievement score of the chat room. Referring to FIG. 7 , when text is input into the conversation input window of the chat room 500 having a public score equal to or higher than the threshold value, the access control unit 330 converts non-standard words such as abbreviations, slang, slang, dialects, buzzwords, or misspellings into the input text. If this incorrect phrase is included, a highlight element (eg, a red underline, etc.) 720 may be applied to the corresponding phrase. In addition to the highlight element, the send button can be replaced with a different color or image from the previous one, or a pop-up requesting reconfirmation of the text can be provided before text transmission when the send button is input. In addition, when the name of a conversation partner included in the chat room 500 is input in the conversation input window, the access control unit 330 uses an honorific word (for example, 'Nim', 'Mr.', 'Mr.', ' Ms.', etc.) can be automatically added and entered. In addition, when a title is input into the conversation input window of the chat room 500 using a mention function, the access control unit 330 determines whether a conversation partner with the corresponding title exists in the chat room 500, and if not, the corresponding A highlight element can be applied to the title, the send button can be replaced with a different color or image, or a pop-up requesting reconfirmation of the title before transmission can be provided when the send button is pressed.

As another example, the access control unit 330 may provide a notification about content to be shared through the corresponding chat room when the public score of the chat room is equal to or greater than a threshold value. In this case, the access control unit 330 may display a warning screen when attempting to share a photo, video, text (clipboard), URL, etc. through a chat room having a public score equal to or higher than the threshold value. In addition, the access control unit 330 may analyze content to be shared through a chat room having a public score equal to or higher than a threshold value, and display a warning screen when, as a result of the analysis, the correlation with the core topic of the corresponding chat room is low. For example, after obtaining a title and a lead by prefetching the contents of a web page of a URL, a pop-up requesting reconfirmation may be provided when the relevance is low compared to the core topic of the chat room. Sharing pictures of swimming or food in a chat room with only documents or screenshots, or sharing a clipboard containing travel information URLs or travel review texts in a chat room where work-related content is the main topic. Reconfirmation can be requested through a pop-up for content of a subject that is not related.

As another example, the access control unit 330 may recommend content for expression of intention through a chat room according to a public score of the corresponding chat room. Contents for expressing intentions are hieroglyphs used to express the user's feelings or thoughts, and may include, for example, emoticons, stickers, etc., and grades may be assigned to the achievement score. At this time, the access control unit 330 may recommend emoticons or stickers of a level corresponding to the achievement score of each chat room. In addition, according to the achievement score of the chat room, a set of content for expressing intention that the user prefers to use may be set, and the set set by the user may be preferentially used in the actual chat room, and may be arranged and recommended.

As another example, the access control unit 330 may create a conversation partner group according to a relationship in the conversation partner list based on the achievement score of the conversation partner. In this case, the access control unit 330 may sort and display the conversation partner list in descending or ascending order based on the achievement score of the conversation partner. Further, the access control unit 330 may create a conversation partner whose public score is equal to or greater than the threshold value as a public conversation group, and may create a conversation partner whose public score is less than the threshold value as a private conversation group. In some cases, conversation partners' grades may be classified based on public scores, and at this time, it is also possible to create a conversation partner group for each conversation partner's rank.

(여기서, Score_min는 대화방 중 가장 작은 공적 스코어, Score_max는 대화방 중 가장 큰 공적 스코어, α는 0에서 1사이의 값으로 변화 민감도를 나타내는 설정 값)일 때를 감지하여 대화방 전환 이벤트를 발생시킬 수 있다. 도 8을 참조하면, 공적 스코어가 임계값 미만인 사적인 대화방(800)을 이용하다가 대화방 목록(801)에서 다른 대화방(500)을 선택하여 진입하는 시점에 현재 진입한 대화방(500)과 이전 대화방(800) 간의 공적 스코어의 변화가 일정 레벨 이상일 때 현재 진입한 대화방(500)에 공적인 대화방으로의 진입을 알리는 경고창(830)을 표시할 수 있다.As another example, when a chat room is switched, the access control unit 330 may generate a chat room switching event and provide a notification to the current chat room when a change in an achievement score between the current chat room and the previous chat room is equal to or greater than a predetermined level. Since many mistakes occur when switching from a chat room with a private relationship to a chat room with a public relationship, it is possible to detect when the public score level of a chat room is greatly changed by monitoring the chat room conversion. The access controller 330 compares the previous chat room's score (Score _previous ) with the current chat room's score (Score _current ),

(Here, Score _min is the smallest achievement score in the chat room, Score _max is the highest achievement score in the chat room, and α is a value between 0 and 1, which is a set value representing change sensitivity) to generate a chat room conversion event. can Referring to FIG. 8 , the currently entered chat room 500 and the previous chat room 800 are entered at the point of entering by selecting another chat room 500 from the chat room list 801 while using a private chat room 800 whose public score is less than the threshold. ), a warning window 830 notifying entry into the public chat room may be displayed in the currently entered chat room 500 when the change in the public score between .

As another example, the access control unit 330 may apply and display a display element of the chat room differently according to the achievement score of the chat room. For example, as shown in FIG. 9 , the border color 940 of a chat room 500 with an achievement score higher than or equal to a threshold value and a chat room 800 with an achievement score lower than the threshold value may be displayed differently. The border color of the chat room (500, 800) is set to the same or similar color to the background color as the achievement score is lower, while it can be set to a complementary color to the background color as the achievement score is higher. When moving between the chat rooms 500 and 800, the achievement level of the current chat room can be naturally and easily grasped through the display elements displayed differently according to the achievement scores.

As another example, the access control unit 330 may sort the chat room list based on the public score of the chat room. In other words, the access control unit 330 may sort and display the chat room list in descending or ascending order according to the achievement score. Alternatively, the access control unit 330 may divide the list into a plurality of grades (eg, high, medium, and low) based on the achievement score, and group and display the list of chat rooms by grade.

As another example, the access control unit 330 may differently apply and display display elements of items representing each chat room in the chat room list according to the achievement score of the chat room. For example, referring to FIG. 10 , the higher the achievement score of a chat room in the chat room list 1050, the darker the background color of the corresponding item may be displayed. Alternatively, in the chat room list 1050, a background color of a corresponding item may be displayed differently from other chat rooms for a chat room having an achievement score equal to or higher than the threshold value, or a separate icon may be displayed for a chat room item having an achievement score equal to or higher than the threshold value.

As another example, when the access control unit 330 wants to share content such as photos, videos, and links in other applications through a messenger, the contact or chat room included in the sharing target list is classified differently from other sharing targets according to the public score. can be displayed For example, referring to FIG. 11 , when a sharing target list 1100 for content sharing is displayed, among messenger contacts or chat rooms included in the sharing target list 1100, the public score is greater than or equal to a threshold value. Items can be highlighted in different colors or displayed as separate icons.

Although it is explained that user access is controlled in the same way when the public score of the chat room is higher than the threshold value, it is not limited to this, and user access is controlled in a differentiated manner by classifying the conversation partner or chat room according to the public score. that is also possible

Therefore, it is possible to analyze the contents of a conversation to determine the degree of achievement for each conversation partner and chat room, and according to the degree of achievement, sorting or displaying the chat room list of the messenger, locking the chat room input, displaying the screen, displaying notifications, correcting the transmission phrase, recommending contents, etc. You can control user access to chat rooms.
