1 is a block diagram of an instant messaging service system according to an embodiment.

Referring to FIG. 1 , user terminals 100 and 110 having installed an instant messaging application access the messaging server 200 and use functions provided by the instant messaging application. The instant messaging application provides the user interface screen described in the present invention. The user interface screen 10 may be a chat room interface screen, as shown in FIG. 1, and is referred to as a chat room screen in the description.

The messaging server 200 is named to indicate a server connected to an instant messaging application. It is not necessary to be limited to the messaging server 200, and any server that performs the operations described in the present invention is sufficient.

For explanation, it is assumed that user A is a user of the terminal 100 , user B is a user of the terminal 110 , and user A and user B are chat rooms. In the description, the chat room screen 10 displayed on the terminal 100 of user A will be described as an example.

The chat room screen 10 may include a message display window 11 in which messages exchanged in the chat room are displayed, a text input window 12 for receiving text, and an emoticon button 13 for opening the emoticon display window 14 . The chat room screen 10 may display an emoticon display window 14 showing a plurality of emoticons when the emoticon button 13 is selected while the keyboard display window 15 for inputting text is displayed.

The emoticon display window 14 may display, in the emoticon list area 17 , a list of emoticons included in the emoticon package of a specific tab among the emoticon tabs 16 in which emoticon packages (products) are listed. The emoticon list means a set consisting of a plurality of emoticons.

When user A inputs text into the text input window 12 and presses a transmit button (not shown), the terminal 100 transmits the input text to the messaging server 200 . The messaging server 200 checks the chat room to which the input text is transmitted, and transmits the input text to the participant terminals of the chat room. Then, the text input by the user A may be displayed as a speech bubble message on the chat room screen 10 in which the user A and the user B participated.

Similarly, when user A selects an emoticon in the emoticon display window 14 and presses a transmit button, the terminal 100 transmits the emoticon to the messaging server 200 . In this case, an emoticon image may be transmitted, or identification information of the emoticon may be transmitted. The messaging server 200 checks the chat room to which the emoticon is transmitted, and transmits the emoticon to participant terminals of the chat room. Then, the emoticon input by the user A may be displayed on the chat room screen 10 in which the user A and the user B participated.

In addition to text or emoticons, user A may select and transmit a video, photo, etc. from the chat room screen 10 , but a detailed description thereof will be omitted.

In this way, user A may input text or an emoticon on the chat room screen 10 , and in particular, through an emoticon instead of text, can effectively and effectively convey his/her emotions and intentions to the other party. However, when user A wants to input an emoticon, he presses the emoticon button 13 and directly searches for the emoticon shown in the emoticon display window 14 to select the desired emoticon. Accordingly, if the number of emoticons increases, it may be difficult for a user to find a desired emoticon, and it may take time to select an emoticon. In addition, even if there are various emoticons, there is a possibility that the user will continue to use only frequently used emoticons, and it may be cumbersome to search for an emoticon suitable for his/her emotions and wishes.

In the following, a method for the instant messaging application to link text input to the text input window 12 with the emoticons provided to the emoticon display window 14 based on the keyword dictionary, and to provide (recommend) emoticons related to the input text Explain. An emoticon related to the input text may be referred to as a recommended emoticon.

For reference, for convenience of description, the instant messaging application may be described as the subject of the operation, or the terminal 100 executing the installed instant messaging application may be described as the subject of the operation.

2 is a diagram schematically illustrating a keyword dictionary-based emoticon providing method according to an embodiment.

Referring to FIG. 2 , the messaging server 200 manages a keyword dictionary including texts matched with the keyword. As shown in Table 1, the keyword dictionary may be composed of a keyword identifier, a keyword, and texts matched with the keyword, and the keyword and the matching text are updated.

keyword identifier keyword
(representative keyword) matching text ID=001 Greetings hello* hi hello banga banga* ID=002 it's okay ok* ok ok ID=003 laughter haha*

The messaging server 200 stores a list of recommended emoticons for each keyword that matches keywords with emoticons that are recommendations. The list of recommended emoticons for each keyword may be composed of a keyword identifier, a keyword, and a list of recommended emoticons matched to the keyword as shown in Table 2, and the keyword and the matched recommended emoticon are updated. The recommended emoticon list consists of emoticons related to keywords.

keyword identifier keyword
(representative keyword) List of recommended emoticons ID=001 Greetings IMG1, IMG2, IMG3, … IMGm ID=002 it's okay IMG1, IMG4, IMG5, … IMGn ID=003 laughter IMG7, IMG8, IMG9, … IMGk

The messaging server 200 may store a list of related keywords for each keyword. The related keyword list for each keyword may be composed of a keyword identifier, a keyword, and a related keyword list matched to the keyword as shown in Table 3, and the keyword and the matched related keyword are updated. Related keywords are also matched with the recommended emoticon list as shown in Table 2.

keyword identifier keyword
(representative keyword) Associated Keywords (IDs) ID=001 Greetings Good morning (ID=11)
Goodbye (ID=40)
Thanks (ID=41) ID=002 it's okay ㅇㅋ (ID=20)
OK (ID=21)
Up (ID=22) ID=003 laughter Smile (ID=30)
Hehe (ID=31)
Laugh (ID=32)

The messaging server 200 transmits the keyword dictionary to the terminal 100 . The terminal 100 may be a subscriber terminal using an emoticon recommendation service, and may download a keyword dictionary when subscribing to the emoticon recommendation service. The keyword dictionary is a data file and is stored in the terminal 100 . Data files may be stored in a database structure. The keyword dictionary stored in the terminal 100 is periodically synchronized with the keyword dictionary of the messaging server 200 . When the keyword dictionary managed as shown in Table 1 is updated, the messaging server 200 transmits the updated keyword dictionary to the terminal 100, thereby synchronizing the keyword dictionary stored in the terminal 100 and the messaging server 200. . Matching text existing in the keyword dictionary is matched to the keyword, and the recommended emoticon list (Table 2) is matched to the keyword existing in the keyword dictionary. Therefore, if the input text exists in the keyword dictionary, it means that there is a recommended emoticon matching the input text.

When text is input, the application of the terminal 100 queries the input text as a keyword dictionary and checks the response result. The response result may include a keyword identifier matched to the input text or a value indicating that there is no matching keyword. A keyword may be included in the response result, but in the description, the keyword is identified by an identifier assigned to the keyword. The response result may include a plurality of keyword identifiers. For texts without matching keywords, the application of the terminal 100 may not recommend emoticons. When the response result includes the keyword identifier, the application of the terminal 100 requests the messaging server 200 to recommend an emoticon for the keyword identifier.

The messaging server 200 refers to a list of recommended emoticons for each keyword (Table 2), extracts a list of recommended emoticons matching the received keyword identifier, and transmits an emoticon recommendation result including the list of recommended emoticons to the terminal 100 . . The messaging server 200 may extract the related keyword list of the requested keyword identifier with reference to the related keyword list for each keyword (Table 3), and transmit the emoticon recommendation result further including the related keyword list to the terminal 100 . .

The application of the terminal 100 displays the emoticon recommendation result of the input text on the screen.

For reference, although the keyword dictionary and the application have been separately described in FIG. 2, the keyword dictionary may be included in the application, downloaded, and installed. Of course, the keyword dictionary can be downloaded and installed separately from the application.

3 is a flowchart of a keyword dictionary-based emoticon providing method according to an embodiment.

Referring to FIG. 3 , the messaging server 200 includes a keyword dictionary including texts matched with keywords (see Table 1), a list of recommended emoticons for each keyword matching keywords with emoticons that are recommended targets (see Table 2), and a keyword A list of related keywords (refer to Table 3) is managed (S110).

The messaging server 200 transmits the keyword dictionary to the terminal 100 (S120). The keyword dictionary may be provided for subscribers of the emoticon recommendation service or paid subscribers. The keyword dictionary is a data file and is stored in the terminal 100 . The keyword dictionary stored in the terminal 100 is synchronized with the messaging server 200 . Text existing in the keyword dictionary is matched to a keyword, and a recommended emoticon list (Table 2) is matched to the matched keyword. Accordingly, if text exists in the keyword dictionary, it can be known that there is a recommended emoticon provided to the text.

The terminal 100 stores the keyword dictionary (S130). The keyword dictionary may be updated by the messaging server 200 .

When a text (eg, “Banga”) is input into the text input window of the screen, the terminal 100 checks a keyword identifier matched with the input text (“Banga”) using a keyword dictionary ( S140 ). The terminal 100 may query the input text (“Banga”) as a keyword dictionary and obtain a response result. The response result may include a keyword identifier (ID=001 of the keyword “greeting”) matched to the input text (“Banga”) or a value indicating that there is no matching keyword. The response result may include a plurality of keyword identifiers. For texts without matching keywords, the terminal 100 does not recommend emoticons. With respect to the text having the matching keyword, the terminal 100 may recommend an emoticon, so that the presence of the recommended emoticon for the input text may be displayed on the screen. A method of indicating that there is a recommended emoticon for the input text may be implemented in various ways. For example, if the application provides an emoticon display window displaying emoticons and is implemented to open the emoticon display window by pressing the emoticon button, the emoticon button may be changed to a hint icon different from the default icon to indicate that there is a recommended emoticon.

If there is a keyword identifier (ID=001) matched to the input text, the terminal 100 requests the messaging server 200 to recommend an emoticon for the keyword identifier (ID=001) (S150). The keyword identifier (ID=001) may be included in the response result. The time at which the terminal 100 requests the emoticon recommendation may vary. For example, when the terminal 100 receives a response result including the keyword identifier (ID=001), the terminal 100 may request an emoticon recommendation for the keyword identifier (ID=001) from the messaging server 200 before the user request. When the terminal 100 receives a request for a recommendation emoticon for the input text from the user (eg, a hint icon selection or input text selection), the terminal 100 may request an emoticon recommendation for the keyword identifier (ID=001) from the messaging server 200 . have. Meanwhile, when the terminal 100 receives the recommended emoticon list from the messaging server 200 , the terminal 100 may store the received recommended emoticon list for a predetermined period of time (eg, one day), and may delete the recommended emoticon list after a predetermined period of time has elapsed. In this case, the terminal 100 may check whether the list of recommended emoticons for the keyword identifier (ID=001) is stored before requesting the emoticon recommendation for the keyword identifier (ID=001) to the messaging server 200 . If there is a list of emoticons recommended for the keyword identifier (ID=001), the terminal 100 does not request the emoticon recommendation for the keyword identifier (ID=001) to the messaging server 200, but the keyword identifier (ID) =001), the keyword identifier (ID=001) may be transmitted to the messaging server 200 if there is no list of recommended emoticons.

The messaging server 200 refers to a list of recommended emoticons for each keyword (Table 2), extracts a list of recommended emoticons matched to the requested keyword identifier (ID=001), and sends an emoticon recommendation result including the recommended emoticon list to the terminal ( 100) (S160). The messaging server 200 extracts the related keyword list of the requested keyword identifier (ID=001) with reference to the related keyword list for each keyword (Table 3), and presents the emoticon recommendation result further including the related keyword list to the terminal 100 ) can be transmitted. Upon receiving the keyword identifier (ID=001), the messaging server 200 extracts a list of recommended emoticons (IMG1, IMG2, IMG3, ...IMGm) matched with the keyword identifier (ID=001). At this time, the messaging server 200 may transmit all of the recommended emoticons list (IMG1, IMG2, IMG3, ...IMGm), but the time point (time zone such as morning, afternoon, evening, day of the week, season, characteristic of the day, etc.), weather, Based on a recommendation criterion such as user preference, the selected emoticon list may be transmitted. The messaging server 200 may transmit to the terminal 100 a keyword related to at least one of good morning (ID=11), goodbye (ID=40), and thank you (ID=41) matched to the keyword identifier (ID=001). have.

The terminal 100 displays the emoticon recommendation result of the input text (“Banga”) on the screen (S170). There may be various methods in which the terminal 100 displays the emoticon recommendation result of the input text (“Banga”) on the screen. The emoticon recommendation result may be displayed on an emoticon display window in which the application displays emoticons. The emoticon recommendation result may include a list of emoticons recommended for the input text, and may further include related keywords. A method of displaying a list of recommended emoticons matched with a related keyword may be various. According to an embodiment, when a related keyword is selected, a list of recommended emoticons matching the related keyword may be displayed on the emoticon display window. According to another embodiment, along with a list of emoticons recommended for the input text, at least some recommended emoticons matching a related keyword may be provided. The user may search for at least some recommended emoticons matching the related keyword while scrolling the emoticon display window.

Meanwhile, the terminal 100 does not display the emoticon recommendation result received from the messaging server 200 as it is, and may adjust the displayed emoticon arrangement or the arrangement of related keywords based on user usage information. For example, the terminal 100 may store the transmitted emoticon and a keyword matched thereto, and learn the user's preferred emoticon. When exposing a list of emoticons matched to a keyword, the terminal 100 may preferentially expose a user's preferred emoticon or a recently used emoticon. The terminal 100 may store a keyword selected from among related keywords recommended for the input text, and learn the user's preferred keyword. When the related keyword is exposed, the terminal 100 may preferentially expose the user's preferred keyword. The terminal 100 may store emoticons and keywords transmitted for each time period, and learn user's preferred emoticons and keywords for each time period. The terminal 100 may expose a list of emoticons or related keywords based on user preferred emoticons and keywords for each time period.

In the following, the user interface screen of the instant messaging application will be described as an example.

4 and 5 are examples of a text-related emoticon recommendation interface screen according to an embodiment.

Referring to Figure 4 (a), the terminal 100 displays a chat room screen. As described in FIG. 1 , the chat room screen displays a message display window 11 and a text input window 12 , and when the cursor is on the text input window 12 , the keyboard display window 15 that can input text is based on can be displayed In addition, the chat room screen displays an emoticon button 13 that opens an emoticon display window, and the emoticon button 13 may be disposed, for example, in the text input window 12 . The emoticon button 13 may be displayed as a basic icon.

Referring to FIG. 4B , text, for example, “okay”, “okay”, “ah”, and “yo” may be sequentially input into the text input window 12 . If the emoticons related to the text “okay” are provided as recommended emoticons, the terminal 100 changes the emoticon button 13 to an icon different from the default icon. From now on, an icon different from the default icon is called a hint icon. For the hint icon, an icon having a shape different from the default icon is sufficient so that the user can know that there is a recommended emoticon associated with the text. Furthermore, the hint icon may pre-display one of the recommended emoticons related to the text “okay”. The hint icon may be an emoticon with movement.

Also, the terminal 100 may display the text with the recommended emoticon separately from the text without the recommended emoticon. For example, the terminal 100 may highlight the text “okay” with the recommended emoticon. Alternatively, the terminal 100 may highlight a word ('it's okay') including the text "it's okay" with the recommended emoticon.

The terminal 100 may determine whether to keep the emoticon button 13 as a basic icon or change it to a hint icon by using the keyword dictionary. The keyword dictionary includes information for confirming the presence or absence of a recommended emoticon associated with the input text, and may be composed of keyword identifiers, keywords, and texts matched to the keywords as shown in Table 1, and the keywords and matching texts are updated. The keyword dictionary may be received from the messaging server 200 .

With reference to the keyword dictionary, the terminal 100 may check whether there is a keyword matched with the input text “okay” and check whether there is a keyword matched with “okay” completed with the next input text “okay”. The terminal 100 may change the emoticon button 13 to a hint icon when it is confirmed through the keyword dictionary that there is a keyword (ID=002) that matches the text “okay”. When the text “ah” and “yo” connected to the text “okay” with the recommended emoticon are input, the terminal 100 may keep the emoticon button 13 as a hint icon. In addition, the terminal 100 may continue to display the highlight of the text “It’s okay” with the recommended emoticon.

Referring to FIG. 4C , when a new word starts in the text input window 12 , the terminal 100 changes the emoticon button 13 from a hint icon to a basic icon. When a space (space bar), line break (enter key), delimiter (comma, period, exclamation point, period, colon, semicolon, etc.) is input in the text input window 12, the terminal 100 returns to the start of a new word. can recognize

When text, for example, “I” and “is” are sequentially input into the text input window 12 , as described in (b), the terminal 100 matches the text “I” through the keyword dictionary It is possible to check whether the keyword has been used, and to change or maintain the emoticon button 13 according to the presence or absence of the keyword. If there is no keyword matched in the text “I”, the emoticon button 13 remains as a default icon.

When the emoticon button 13 of the basic icon is selected, the terminal 100 displays the stored emoticons regardless of the input test. For example, when the emoticon button 13 of the basic icon is selected, the terminal 100 may display emoticons including the last used emoticon on the emoticon display window 14 .

Referring to (d) of FIG. 4 , when new text, for example, “ㅋ” is sequentially input to the text input window 12, the terminal 100 matches the text “ㅋ” through the keyword dictionary. The presence or absence of a keyword may be checked, and the emoticon button 13 may be changed or maintained according to the presence or absence of a keyword.

As a result of querying the text “ㅋ” in the keyword dictionary, the terminal 100 determines that there is a keyword (ID=003) matching the text “ㅋ”, and the terminal 100 uses the emoticon button 13 as a hint icon. change The hint icon for “blah” may be different from the hint icon for “okay”.

The terminal 100 may highlight the text “lol” with the recommended emoticon.

When the emoticon button 13 is selected in a state in which the text “ㅋ” is input, the text selected in the text input window 12 may be displayed separately. In this case, the highlight of the selected text “ㅋ” may be displayed differently from the highlight of “ㅋ” before selection. For example, a box may be displayed as a highlight in the text “blah” before selection, and an underline in the selected text “blah” may be displayed as a highlight. In addition, the highlight method may be set in various ways, such as bold text, color, italic text, and the like.

Meanwhile, a highlight may be continuously displayed to indicate that there is a recommended emoticon that is “okay” among the text input into the text input window 12 . When the highlighted “okay” is selected, the terminal 100 may display recommended emoticons of the text “okay” instead of the recommended emoticons of the text “blah”.

When the hint icon of the text “lol” is selected or the highlighted text “okay” is selected, the terminal 100 may display the recommended emoticons received from the messaging server 200 on the emoticon display window 14 . Accordingly, emoticons not stored in the terminal 100 may also be recommended to the user.

Next, while explaining the emoticon recommendation interface screen, continuous alphabets are given to the interface screen displayed on the terminal 100 so as to have continuity with the interface screen described with reference to FIGS. 2A to 2D .

Referring to FIG. 5 , when the emoticon button 13 changed to a hint icon in FIG. 4(d) is selected, as shown in (e), the terminal 100 displays the text “ㅋ” in the emoticon display window 14 as a recommended emoticon. Displays the emoticon recommendation results including The recommended emoticons may be a list of recommended emoticons of a keyword (ID=003) matched to the text “ㅋ”. The recommended emoticon list may include emoticons received from the messaging server 200 . A method for displaying an emoticon recommendation result on the emoticon display window 14 and a method for arranging emoticons may be variously implemented.

The emoticon recommendation result may further include keywords related to the text “lol” (eg, “laugh”, “smile”, etc.). According to one embodiment, related keywords may be displayed on the keyword tab 18 of the emoticon display window 14 . When a related keyword is selected, recommended emoticons matching the selected related keyword may be displayed in the emoticon list area 17 . The user may select a related keyword and search for recommended emoticons matched to the related keyword. This can be called a 2 depth search. The position of the keyword tab 18 may be variously determined.

In the description, it is explained that the related keywords are displayed on the keyword tab 18. According to another embodiment, along with the recommended emoticons of the text “ㅋ” in the emoticon display window 14, at least some recommendations matching each related keyword Emoticons may be provided together. The user may search for at least some recommended emoticons matched to each related keyword while scrolling the emoticon display window 14 . This can be called scroll navigation. The user may search for a larger number of recommended emoticons through a view more button that can further check the recommended emoticons of each related keyword.

Referring to (f) of FIG. 5 , in (e), the highlighted text “okay” may be selected. The terminal 100 displays the emoticon recommendation result for the text “okay” on the emoticon display window 14 . Since the text “okay” is selected, the text “okay” is changed to a mark indicating the selected text (eg underline), and the text “blah” is changed to a display indicating text with a suggested emoticon (eg a box) can be changed. The terminal 100 may display the recommended emoticons of the text “okay” on the emoticon display window 14 . The recommended emoticons may be a list of recommended emoticons of a keyword (ID=002) matched to the text “okay”, and are received from the messaging server 200 .

The emoticon recommendation result displayed on the emoticon display window 14 displays a list of recommended emoticons of a keyword (ID=002) matched with the text “okay”. In addition, the emoticon display window 14 displays related keywords of the matched keyword (ID=002) matched to the text “okay”, for example, “ㅇㅋ”, “like”, and “up” in the keyword tab 18 . can be displayed

When there are a plurality of related keywords of the keyword (ID=002) matched with the text “okay”, the related keywords displayed on the keyword tab 18 may be sorted by the related keyword recommendation logic. The related keyword recommendation logic may include at least one condition, and the sort order of the related keywords may be determined using the plurality of conditions. For example, the related keyword recommendation logic may include the intensity of emotion represented by the keyword as a condition, and may be used as a condition in which the keyword having the strong emotion is first exposed. The related keyword recommendation logic may include, as a condition, the cumulative number of times each related keyword is selected from among the related keywords of the input text, and may be used as a condition in which popular keywords are exposed first. The related keyword recommendation logic may include the matching number of emoticons frequently sent in the chat room where the text “It’s okay” is input, and it can be used as a condition that keywords containing a lot of emoticons frequently used by the conversationalists are exposed first. . The related keyword recommendation logic may include the number of emoticons matched to the keyword as a condition, and may be used as a condition in which keywords with a large number of emoticons are first exposed.

On the other hand, if the number of related keywords is greater than or equal to the number (eg, three) displayed on the keyword tab 18 , a more button may be exposed on the keyword tab 18 , and all related keywords may be displayed when the more button is clicked. Alternatively, when the user scrolls the keyword tab 18 , hidden keywords in the keyword tab 18 may be displayed.

Referring to (g) of FIG. 5 , when the keyword “like” is selected in the keyword tab 18 , the terminal 100 may display emoticons matching the keyword “like” in the emoticon list area 17 .

When the terminal 100 brings from the messaging server 200 a list of recommended emoticons of the keyword (ID=002) matched to the text “okay”, the related keywords (for example, “ㅇㅋ”, “like”, “up ”) may be brought together, at least a portion of the list of recommended emoticons matched to the related keywords may be brought, or the list of recommended emoticons matched to some keywords among the related keywords may be brought. Alternatively, when the keyword “like” is selected, the terminal 100 may bring a list of recommended emoticons matching the selected keyword “like”. The list of recommended emoticons brought by the terminal 100 from the messaging server 200 may be stored in a designated place for a certain period of time and deleted.

In this way, the emoticon recommendation result of the text is displayed on the emoticon display window 14, and may consist of 2 depths. That is, the emoticon recommendation result may display the keyword tab 18 for recommending a plurality of related keywords, and display emoticons matching the keyword selected from the keyword tab in the emoticon list area 17 . As such, as the emoticon recommendation result, keywords in the keyword tab 18 may be set to depth 1 , emoticons matching the selected keyword may be set to depth 2 , and recommendation results set to depth 1 and depth 2 may be provided. The user can do a 2-depth search in the emoticon recommendation result, and through this, various emoticon recommendations related to the input text can be received, and as a result, the use of the emoticon can be increased.

6 is a flowchart of a method for providing an emoticon according to an embodiment.

Referring to FIG. 6 , the terminal 100 stores a keyword dictionary that can check whether there is a recommended emoticon associated with the input text ( S210 ). As shown in Table 1, the keyword dictionary stores keywords with recommended emoticons, and each keyword has at least one related text as a member. That is, the keyword may be referred to as a representative keyword representing various texts classified as members. On the other hand, any input text may belong to several keywords.

When text is input into the text input window 12 , the terminal 100 queries the keyword dictionary to determine whether there is a recommended emoticon associated with the input text ( S220 ). The terminal 100 may query a keyword corresponding to the input text from the keyword dictionary, and check whether or not a recommended emoticon is present based on the response result.

When there is a keyword matching the input text, the terminal 100 changes the emoticon button 13 to a hint icon different from the basic icon (S230). A method of indicating that there is a recommended emoticon may be a hint icon, but in addition to the hint icon, it may be displayed in various ways in a chat room. The terminal 100 may distinguish and display input text having a matching keyword, for example, may highlight the input text.

When the hint icon is selected, the terminal 100 displays an emoticon recommendation result related to the input text on the emoticon display window 14 (S240). Alternatively, when the highlighted input text is selected, the terminal 100 may display an emoticon recommendation result related to the input text on the emoticon display window 14 . The terminal 100 may transmit the keyword identifier of the input text to the messaging server 200 and receive an emoticon recommendation result matched with the keyword from the messaging server 200 . Here, the keyword identifier may be included in the response result of the keyword dictionary. When a hint icon is selected or a highlighted input text is selected, the terminal 100 may request an emoticon recommendation result related to the input text from the messaging server 200 . Alternatively, when it is confirmed that there is a keyword matching the input text, the terminal 100 may bring an emoticon recommendation result in advance before selecting a hint icon or selecting a highlighted input text. Alternatively, the terminal 100 may store the emoticon recommendation result of the keyword for a predetermined time and use the stored emoticon recommendation result.

When a hint icon is not selected and a new word is input, the terminal 100 changes the hint icon back to a basic icon and checks whether there is a recommended emoticon associated with the new input text (S250).

As such, the terminal 100 may continuously check whether or not a recommended emoticon for the input text is present until the message is transmitted, and transmit at least one of the text and the emoticon according to the user's selection. For example, when a certain emoticon is selected from the emoticon recommendation result and a transmit button is selected, the terminal 100 transmits the selected emoticon to the messaging server 200 . Naturally, no emoticon is selected from the emoticon recommendation result, and the send button may be selected, and the terminal 100 transmits the text input in the text input window to the messaging server 200 .

As such, the terminal 100, for example, when "I'm okay I haha" is sequentially inputted into the text input window, until the send button for the input text is selected, the terminal 100 continues whether or not there is a recommended emoticon associated with the input text through the keyword dictionary. Check it. The terminal 100 displays a hint icon if there is a text with a recommended emoticon to inform the user that there is a recommended emoticon, and displays an emoticon recommendation result when the hint icon is selected. can provide When there are a plurality of texts having a recommended emoticon in the text input window 12 , the terminal 100 may highlight and display any one of the plurality of texts, and provide an emoticon recommendation result of the selected text.

The terminal 100 may receive the emoticon recommendation result from the messaging server 200 . Accordingly, the user may be recommended an emoticon that is not stored in the terminal.

The emoticon recommendation result may include an emoticon list of keywords matched with the input text, and may further include related keywords of the keywords matched with the input text. Keywords related to the keyword representing the input text may be matched to the messaging server 200 . A list of emoticons to be provided for each keyword may be matched to the messaging server 200 .

Relevant keywords included in the emoticon recommendation result may be selected based on various statistical information reflecting user usage patterns, correlation information analyzed by an artificial intelligence model, and the like. The sort order of the related keywords may be determined by the related keyword recommendation logic.

The emoticons included in the emoticon recommendation result may be selected based on various statistical information reflecting user usage patterns, correlation information analyzed by an artificial intelligence model, up-to-dateness, popularity, and the like. The emoticon sort order may be determined by emoticon recommendation logic. If there is a user's favorite emoticon among the emoticons matched to the keyword, the favorite emoticon may be first exposed.

As described above, according to the embodiment, the terminal can quickly display the presence or absence of a recommended emoticon matched with the input text through the keyword dictionary. In addition, according to the embodiment, since the terminal stores the keyword dictionary, it is possible to check the presence or absence of a recommended emoticon matched with the input text without being affected by a delay in real-time communication with a server providing a recommended emoticon.

According to the embodiment, since the server does not need to check that there is a recommended emoticon in real time for texts input from all terminals and transmit the checked information to the corresponding terminals, the load can be reduced.

According to an embodiment, by simply entering text into the text input window, without the need to search for an emoticon, the user can quickly check whether there is a recommended emoticon matching the text, and can easily search for the recommended emoticon matching the input text. have.

According to an embodiment, since the server provides recommended emoticons related to the input text, the user may be recommended emoticons not stored in the terminal.

The embodiment of the present invention described above is not implemented only through the apparatus and method, and may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium in which the program is recorded.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims are also provided. is within the scope of the right.
