  Next, a keyword search system 10 through interaction according to an embodiment of the present invention will be described with reference to FIG.

  FIG. 1 is a configuration diagram of a keyword search system 10 according to an embodiment of the present invention.

  A keyword search system 10 according to an embodiment of the present invention includes a terminal 100, an instant message server 110, and a search server 120.

  The terminal 100 displays a chat room including one or more instant messages. Here, the chat room may be generated by an application that provides an instant message service or an instant message service installed in a terminal. The terminal user can exchange instant messages with users of one or more other terminals through the chat room generated in the terminal 100.

  The terminal 100 generates a search page by extracting one or more keywords from one or more instant messages by receiving the interaction of the terminal user in the chat window displaying the chat room, and generating the generated search page. Display the page.

  If the terminal user selects any one keyword on the displayed search page, the terminal 100 transmits the keyword selected by the terminal user to the instant message server 110, and the search result is received from the instant message server 110. Receive. Further, the terminal 100 generates a search result page including the received search result, and displays the search result page. Here, the search result for the selected keyword may be a search result received from the search server 120 by the instant message server 110.

  The instant message server 110 transmits the instant message transferred by the terminal 100 to another terminal. Then, the instant message server 110 generates a query including the keyword transferred by the terminal 100 and transfers it to the search server 120, receives a search result for the query generated by the search server 120, and transmits it to the terminal 100.

  The search server 120 receives a query for search generated based on the keyword selected by the terminal user from the instant message server 110, and performs a search for the received query. Then, the search server 120 transfers the search result for the query to the instant message server 110 so as to transmit it to the terminal 100.

  Here, the instant message server 110 and the search server 120 may be separated and executed on independent server computers, or may be installed as a server program on the same server computer and serviced. The search server 120 may be an external search server connected to the instant message server 110 via a network or a portal that provides a search service.

  The keyword search system 10 extracts keywords included in the instant message in the chat room of the terminal 100 according to the interaction input by the terminal user at the terminal 100, and uses the keyword search result generated by the search server 120. It is displayed on the terminal 100. That is, the keyword search system 10 is a system that can search for keywords included in an instant message in the chat window of the terminal 100.

  Specifically, the terminal 100 included in the keyword search system 10 displays a chat window including one or more instant messages in a chat room. If the terminal 100 receives an interaction of a terminal user who wants to search for a keyword using an instant message, the terminal 100 extracts one or more keywords from one or more instant messages included in the chat room.

  Here, the instant message for extracting a keyword may be an instant message included in a chat window in which a chat room is displayed. Further, the instant message from which the keyword is extracted can be an instant message included in a predefined search range.

  Then, the terminal 100 extracts one or more keywords from the instant message based on the stored search index list. Here, the stored search index list may be stored by using the keyword already extracted by the terminal 100 as an index. The stored search index list may include the search index list received from the instant message server 110.

  Also, the terminal 100 parses the instant message and extracts keywords. At this time, the terminal 100 parses the instant message to extract one or more words, and extracts one or more keywords from the one or more words extracted based on the text mining technique. .

  Then, the terminal 100 generates a search page based on the extracted keyword, and displays the generated search page. If the terminal user selects any one of the keywords included in the displayed search page, the terminal 100 transfers the selected keyword to the instant message server 110.

  Upon receiving the keyword selected by the user from the terminal 100, the instant message server 110 generates a query including the received keyword and transfers it to the search server 120. The search server 120 that has received the query performs a search for the query and transfers the search result for the query to the instant message server 110. The instant message server 110 receives the search result corresponding to the keyword from the search server 120. Then, the instant message server 110 transfers the search result received from the search server 120 to the terminal 100.

  The terminal 100 that has received the search result from the instant message server 110 displays a search result page corresponding to the selected keyword on the displayed chat window. Therefore, the terminal user can check the search result for the desired keyword on the search result page of the terminal 100. Then, the terminal user returns to the chat room used before the search, for example, by clicking a button corresponding to the “close” command included in the search result page of the terminal 100.

  On the other hand, the terminal 100 displays, separately from one or more keywords included in the search page, the keyword for which the terminal user has confirmed the search result so as to be distinguished from other instant message keywords. And the terminal 100 distinguishes and displays the speech balloon in which the instant message containing the said keyword is displayed among the instant messages contained in the chat room.

  If the terminal user confirms the search result, the keyword for which the search result has been confirmed is displayed separately so as to be distinguished from other instant messages, and the terminal 100 selects the displayed keyword separately from the terminal user. If an input is received, a search result page corresponding to the keyword is provided. Here, the terminal 100 according to an embodiment of the present invention not only provides a search result page when the terminal user clicks on a keyword displayed in the instant message included in the balloon area, The search result page is also provided when clicking the “confirm search result” tap in the pop-up menu provided through selection of the balloon area.

  Furthermore, when the terminal 100 according to an embodiment of the present invention displays one or more keywords included in the search page, the keyword that the terminal user has already confirmed the search result is a keyword that has not confirmed the search result. The keywords that have already been confirmed in the search results are displayed separately.

  Hereinafter, a terminal 100 that searches for a keyword through interaction according to an embodiment of the present invention will be described with reference to FIGS. 2 to 6.

  FIG. 2 is a block diagram of the terminal 100 that searches for a keyword through interaction according to an embodiment of the present invention.

  The terminal 100 according to an embodiment of the present invention includes a display module 200, a memory 210, a processor 220, a communication module 230, and an input module 240.

  The display module 200 displays a chat room that includes one or more instant messages.

  The memory 210 stores a keyword search program. Here, the memory 210 is a generic term for a non-volatile storage device that maintains stored information without power supply, and a volatile storage device that requires electricity to maintain stored information. .

  The communication module 230 performs data communication with the instant message server 110.

  The input module 240 also receives terminal user interaction. Here, the input module 240 may be an input device such as a keyboard, a mouse, a joystick, and a touch pad. In addition, the input module 240 may be a resistive screen type or capacitive type touch screen panel, and may be integrated with the display module 200.

  The processor 220 according to an embodiment of the present invention displays a chat room including one or more instant messages through the display module 200. Further, the processor 220 executes a keyword search program stored in the memory 210.

  In the chat window where the chat room is displayed, if the terminal user inputs an interaction, the processor 220 extracts one or more keywords from the one or more instant messages included in the chat room in response to the interaction. To do.

  Here, the instant message for extracting a keyword may be an instant message included in a chat window in which a chat room is displayed. In addition, the instant message for extracting the keyword may be an instant message included in a predetermined search range such as a number, date, and time. For example, if the predetermined search range is a predetermined number, the instant message for extracting the keyword is a predetermined number of instant messages generated immediately before the terminal user inputs the interaction.

  Here, the predetermined search range may be a value stored in the memory 210 in advance. Further, the predetermined search range may be set by the instant message server 110 and transferred to the terminal 100. The predetermined search range can be set according to the size of the input range of interaction that the terminal user inputs into the chat window.

  In addition, the predetermined search range may be a specific position or place. For example, if the predetermined search range is the current position, the processor 220 extracts a keyword for the instant message generated at the current position. If the predetermined search range is “Seoul”, the processor 220 extracts a keyword for the instant message exchanged by the terminal user for “Seoul”.

  Here, the terminal 100 may include a position sensor 250 to measure the position. At this time, the position sensor 250 may include one or more sensors that measure a position, such as a global positioning system (GPS) and a geo-magnetic sensor (Geo-magnetic Sensor). In addition, the terminal 100 can measure the position of the terminal 100 based on the communication module 230. The communication module 230 can measure the position of the terminal 100 based on information collected by a communication device such as an access point and a base station connected to the communication module 230.

  On the other hand, the interaction means an operation for a specific input by the terminal user, and is input through the input module 240. For example, the interaction may be a click, a tap, a drag and drop, a swipe, a pinch in / out, and a flick (pin) that the terminal user inputs through the input module 240. flick). If the input module 240 is a touch panel that supports multi-touch, the terminal user can input an interaction using a tool such as a finger or a touch pen.

  Pinch-in / out means an operation of opening or closing the finger while maintaining the touch after the terminal user touches the input module 240 using two fingers. Here, when two fingers are opened, it is called a pinch out, and when two fingers are narrowed, it is called a pinch in.

  Further, the interaction may be input using a sensor included in the terminal 100. For example, the terminal user can input a shake and a flip using a gyroscope sensor included in the terminal 100 that manages the chat room.

  Meanwhile, the processor 220 extracts keywords from the instant message according to the interaction input by the terminal user through the input module 240. Then, the processor 220 generates a search page based on the extracted keyword. The process of keyword extraction and search page generation will be described with reference to FIG.

  FIG. 3 is a view showing an example of a chat window and a search page according to an embodiment of the present invention.

  In the chat window P300 displayed on the display module 200, if the terminal user inputs the interaction P310, the processor 220 responds to the interaction by one of one or more instant messages P301 to P307 included in the chat room. The above keywords are extracted. Here, the instant message for extracting the keyword may include instant messages P301 and P306 input by the terminal user and instant messages P302 to P305 and P307 transferred by the conversation partner participating in the chat room.

  The processor 220 extracts keywords from the one or more instant messages P301 to P307 based on the search index list. Here, the search index list may be one in which the keyword already extracted by the processor 220 becomes an index and is stored in the memory 210. The search index list may also include a search index list received from the instant message server 110 through the communication module 230. When receiving an interaction from the terminal user, the processor 220 receives a new search index list from the instant message server 110 through the communication module 230 and adds the received search index list to the search index list stored in the memory 210. .

  For example, the processor 220 receives from the instant message server 110 a search index list including keywords that are frequently searched by the search server 120 by other terminals through the communication module 230, and adds the search index list to the search index list stored in the memory 210. . Further, the processor 220 receives a search index list including keywords extracted by other terminals through the communication module 230 and adds it to the search index list stored in the memory 210. Then, the processor 220 receives a new search index list including new coined words and issue keywords from the instant message server 110 through the communication module 230 and adds it to the search index list stored in the memory 210.

  The processor 220 calculates the similarity between the one or more keywords included in the search index list and the text included in the instant message from which the keywords are extracted. Then, the processor 220 extracts a keyword based on the calculated similarity result value. The processor 220 generates a search page including the extracted keyword. Thereby, the extracted keyword is exposed to the terminal user through the search page. Further, the processor 220 extracts a similar keyword having a similarity with the extracted keyword that is equal to or greater than a preset value from the keywords included in the search index list, and the search page displays the extracted keyword. And one or more of similar keywords.

  Here, the processor 220 generates a search page by arranging the keywords in ascending or descending order in descending order of similarity among the plurality of keywords. For example, the similarity is a similarity between two texts such as a cosine similarity, a Jacquard index, a Spearman similarity, and a dice coefficient (Dice's coefficient). In addition to the measure to be measured, a measure used in information retrieval such as TF-IDF (term frequency-inverse document frequency) and page rank may be used, but is not limited thereto. It is not something.

  In addition to extracting keywords based on the search index list, the processor 220 can extract the keywords by performing a parsing method on the instant message from which the keywords are extracted. Here, the processor 220 extracts a plurality of words from the instant message by performing a parsing method based on the morphological analyzer.

  If a plurality of words are extracted through the parsing method, the processor 220 extracts one or more keywords from the extracted words based on a text mining technique. Here, the text mining technique is a technique for extracting meaningful data from unstructured text based on natural language processing, machine learning, and statistical techniques.

  For example, the processor 220 extracts keywords for a plurality of words based on the number of appearance frequencies in the chat room. Further, the processor 220 measures scores for a plurality of words, and extracts keywords based on the measured scores. Here, the score may be entropy, chi-square statistic, TF-IDF, page rank, and the like.

  Then, the processor 220 extracts a meaningful word as a keyword from the extracted plurality of words. For example, the processor 220 extracts a word meaning a place or a position from the extracted words as a keyword. In addition, the processor 220 extracts words that are important in context as keywords, or analyzes opinions included in the context and extracts them as keywords.

  Referring to FIG. 3 again, for example, the processor 220 compares the text in the instant messages P301 to P307 displayed in the chat window 300 displayed on the display module 200 with the search index list or parses the text. Four keywords P321 to P324 are extracted. Then, the processor 220 generates a search page 320 by arranging the four extracted keywords P321 to P324.

  At this time, if there is no keyword extracted from the instant message or the keyword desired by the terminal user is not extracted, the processor 220 may search the search page for the desired keyword “search term”. Add "input screen" or "search button". For example, if the terminal user directly inputs a keyword on the “search word input screen”, the processor 220 transmits the input keyword to the instant message server 110 through the communication module and receives the search result. In addition, if the terminal user inputs an interaction for selecting the “search button”, the processor 220 allows an external application such as an application corresponding to the search server 120 and a web browser so that the terminal user can search for a keyword. Etc.

  Meanwhile, after extracting the keyword, the processor 220 provides a search page including the extracted keyword to the terminal user through the display module 200. If the terminal user selects any one of the extracted keywords, the processor 220 transmits the selected keyword to the instant message server 110 through the communication module 230.

  The instant message server 110 that has received the selected keyword generates a query including the extracted keyword. Then, the instant message server 110 transfers the generated query to the search server 120.

  The search server 120 that has received the query performs a search for the query and generates a search result for the selected keyword. Then, the search server 120 transfers the generated search result to the instant message server 110.

  Here, the instant message server 110 can directly transfer the received search result to the terminal 100. At this time, the processor 220 of the terminal 100 that has received the search result through the communication module 230 generates a search result page including the received search result. Then, the processor 220 displays the generated search result page through the display module 200.

  Further, the instant message server 110 may generate a search result page including the received search result, and transfer the generated search result page to the terminal 100. At this time, the processor 220 that has received the search result page through the communication module 230 displays the received search result page on the terminal 100 through the display module 200.

  In addition, the search result received from the instant message server 110 and displayed on the terminal 100 may be provided not only in the form of a search page but also in the form of an instant message.

  On the other hand, according to the size of the display module 200, the processor 220 generates a search result page including only a part of the search result for the keyword that the terminal user is to search. That is, the search result page may be a list of search results having a high similarity among the search results for the keyword to be searched by the terminal user. Accordingly, the processor 220 provides a next search result confirmation menu or button so that a search result not included in the search result page can be confirmed.

  For example, if the search result received by the processor 220 is 10 and the search results that can be displayed on the display module 200 are 4 at a time, the processor 220 extracts 4 search results in descending order of similarity. Then, a search result page including the four extracted search results is generated. At this time, the search result page includes a “next search result confirmation” button for confirming the remaining six search results. Then, the processor 220 displays the generated search result page on the display module 200.

  If the terminal user selects the “Confirm next search result” button, the processor 220 generates a search result page including four search results in descending order of similarity among the remaining six search results. , Display on the display module 200. At this time, the search result page includes a “confirm previous search result” button for confirming four previously displayed search results and a “next search result confirm” button for confirming the remaining search results.

  As another example, if the terminal user inputs an interaction for selecting the “confirm next search result” button, the processor 220 provides the terminal user with a web viewer that can confirm an integrated search result including all 10 search results. To do.

  On the other hand, if the terminal user selects any one of the search results included in the search result page, the processor 220 provides detailed information on the selected search result. Here, the processor 220 may provide a web viewer to provide detailed information. The processor 220 may provide detailed information through an external application such as an application corresponding to the search server 120 and a web browser.

  Then, the processor 220 provides a return menu or a return button to the search result page so that the terminal user can return to the chat room after confirming the search result. If the terminal user selects the return menu or the return button, the processor 220 closes the search result page and displays the chat room.

  On the other hand, the processor 220 displays the keyword extracted from the instant message so that the keyword for which the terminal user has confirmed the search result is distinguished from the keyword for which the search result has not been confirmed. For example, the distinct display may be to change to a font different from the keyword font included in the search page. Further, the distinguished display may be to change the attribute of the font included in the search result page. Here, the font attribute may be underline, italic, highlight display, or the like.

  In addition, the processor 220 displays a keyword for which a terminal user confirms a search result included in one or more instant messages included in a chat room so that the keyword is distinguished from other instant message keywords. To do. For example, for a keyword for which the terminal user has confirmed the search results, the processor 220 changes the font so that the keyword or instant message including the keyword is distinguished from other instant messages or keywords included in the chat room. Or by adding underline and highlighting. In addition, the processor 220 includes a distinguished display for a balloon displaying an instant message including a keyword that the terminal user has confirmed the search result among the instant messages included in the chat room.

  Then, if the terminal user inputs a keyword, an instant message, or an interaction for selecting a balloon, the terminal 220 displays a search result page corresponding to the keyword. Alternatively, the processor 220 displays a pop-up menu including a “search result” menu for displaying a corresponding search result page. Then, if the terminal user selects “search result” from the pop-up menu, the processor 220 displays a search result page.

  In addition, when the processor 220 displays one or more keywords included in the search page, the processor 220 distinguishes between keywords that have been confirmed by the terminal user and keywords that have not been confirmed. Display confirmed keywords separately. Then, the processor 220 displays the separately displayed keywords on the search page. The terminal user can discriminate between a keyword that has already been confirmed as a search result and a keyword that has not been confirmed as a search result, through a search result page that includes keywords displayed in this manner.

  As described above, the terminal 100 according to the embodiment of the present invention can quickly and easily search for a keyword included in an instant message by an interaction input through the input module 240 without terminating the chat room by the terminal user. be able to. Hereinafter, a keyword search between the conventional terminal and the terminal 100 according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4.

  FIG. 4 is an exemplary diagram of a keyword search performed by a conventional terminal.

  Referring to FIG. 4, when exchanging instant messages in a chat window and searching for a keyword included in the instant message, the conventional terminal starts operating from the chat window 400. The menu screen 410 is moved through the input P400 that moves to the menu screen 410 provided by the user. The terminal user executes a search application or a web browser application on the menu screen 410, and performs a search by directly inputting a keyword P420 to the search screen 420 of the search application or the web browser. Then, after confirming the search result 430, the terminal user returns to the chat window by switching the application and returning to the chat window, or by re-executing the application that provides the chat window.

  In contrast, referring again to FIG. 3, if the terminal user inputs the interaction P310 in the chat window 300, the processor 220 provides a search page from which keywords can be selected. If the terminal user selects a keyword on the search page, the processor 220 displays a search result page including the search result of the selected keyword on the display module 200. The terminal user confirms the search result through the search result page, and returns to the chat window 300 by closing the screen on which the search result page is displayed.

  On the other hand, if the terminal user inputs an interaction, the processor 220 extracts a keyword from an instant message that matches a preset condition. Here, the preset condition may be one or more instant messages displayed in the chat window through the display module 200. The processor 220 extracts keywords for one or more instant messages displayed in the chat window through the display module 200. Here, the interaction may be a pinch out, for example.

  Further, the preset condition may be a preset time range. The processor 220 extracts keywords from the instant message received by the terminal 100 within a preset time range. For example, if the preset time is 1 hour, the processor 220 extracts and extracts the instant messages from the time when the interaction is input up to 1 hour before the instant messages included in the chat room. Extract keywords from instant messages.

  The preset condition may be a search range set according to the size of the interaction input range input by the terminal user. The processor 220 sets a search range according to the size of the input range of interaction input by the terminal user in the display module 200. Then, the processor 220 extracts a keyword from the instant message included in the set search range.

  Here, the search range may be the date or time when the instant message was generated. The search range may be the number of keywords extracted from the instant message. The search range may be set in advance and stored in the memory 210, or may be set by the instant message server 110 and received through the communication module 230. The search range may be set by the terminal user through the interaction. Hereinafter, the search range set in accordance with the size of the interaction input range by the terminal user will be described with reference to FIG.

  FIG. 5 is a view showing an example of a search range set according to the size of the interaction input range according to an embodiment of the present invention.

  As shown in FIG. 5A, when the terminal user inputs a pinch-out interaction, the terminal user inputs an interaction in a range corresponding to the innermost circle P500 smaller than (b) and (c) in FIG. For example, the processor 220 sets the search range smaller than (b) and (c) of FIG. 5 according to the preset search range. Further, as shown in FIG. 5C, if the terminal user inputs a wider range of interaction than FIG. 5A and FIG. 5B like the outermost circle P520, the processor 220 may According to the set search range, the search range is set larger than (a) and (b) in FIG.

  For example, when setting the search range so as to change the date according to the length of the pinch-out interaction, as shown in FIG. If an interaction having a size corresponding to the innermost circle P500 smaller than (c) is input, the processor 220 sets the search range to one day according to the input pinch-out length P500. Accordingly, the processor 220 extracts keywords for instant messages generated one day before the terminal user inputs the interaction.

  Further, as shown in FIG. 5B, if the terminal user inputs an interaction having a size corresponding to the second circle P510 from the inside, the processor 220 sets the search range to two days. Therefore, the processor 220 extracts keywords based on the instant message generated two days before the terminal user inputs the interaction according to the input pinch-out length P510.

  Also, as shown in FIG. 5C, if the terminal user inputs an interaction with the third circle size P520 from the inside, the processor 220 sets the search range according to the pinch-out length P520. Set to 3 days. Therefore, the processor 220 extracts keywords by targeting instant messages generated three days before the terminal user inputs the interaction.

  When the terminal user inputs an interaction on the search page, the processor 220 according to the embodiment of the present invention does not extract the keyword because the instant message included in the chat room is not included in the search range. One or more additional keywords are extracted from the instant message. Here, as described above, the search range may be an instant message displayed on the display screen in the chat window and an instant message generated by at least one of a preset time, date, and position.

  For example, if the search range is an instant message within one hour, the processor 220 extracts a keyword based on the instant message within one hour, and displays a search page generated by the extracted keyword. If the terminal user inputs an interaction on the search page, the processor 220 additionally extracts keywords for instant messages that are not included in the search range. Then, the processor 220 generates a search page including the searched keyword and displays it.

  Then, the processor 220 displays the extracted keyword on the search page. Here, the interaction may be scrolling, for example. This will be described with reference to FIG.

  FIG. 6 is a view illustrating a method for searching for a keyword through interaction on a search page according to an embodiment of the present invention.

  If the search range is an instant message currently displayed in the chat window, the processor 220 extracts one or more keywords as shown in FIG. 6A from the instant message currently displayed. If the terminal user inputs an interaction on the search page, the processor 220 re-extracts the keyword from the instant message in which the keyword was not extracted because it was out of the search range. Then, the processor 220 displays the re-extracted keyword on a search page as shown in FIG.

  Here, the instant message from which the keyword is not extracted may be an instant message generated before the instant message from which the keyword is extracted among the instant messages included in the chat room. In addition, the instant message from which the keyword is not extracted may be an instant message generated after the instant message reflected on the search result page.

  On the other hand, if the terminal user inputs an interaction in the chat window in which the chat room is displayed, the processor 220 generates and displays a search page including a keyword previously searched by the terminal user in the chat room. For example, if the terminal user inputs an interaction in a chat window displayed in a chat room, the processor 220 generates a search page including the already searched keywords previously searched by the terminal user in the chat room. Then, the processor 220 displays a search page including the already searched keyword.

  As described above, the keyword extracted according to an embodiment of the present invention may be a keyword extracted from an instant message included in a chat room in which a terminal user inputs an interaction. However, the keyword extracted according to another embodiment of the present invention may be a keyword extracted from a plurality of chat rooms between the terminal user and the specific user. For example, if the terminal user inputs an interaction, the keyword extracted from the instant message included in the chat room and the other chat room including the user who exchanges the instant message with the terminal user in the chat room. A search page including the generated keywords is generated and displayed.

  Meanwhile, the processor 220 displays a predetermined number of keywords on a search page displayed on the display module 200. Therefore, the terminal user inputs an interaction in order to check keywords that exceed a preset number on the search page. For example, if the terminal user inputs an interaction for confirming the next keyword on the search page, the processor 220 performs a search because a preset number of keywords extracted from the instant message included in the chat room has been exceeded. A search page including keywords that are not included in the page is generated and displayed on the display module 200.

  Meanwhile, according to an embodiment of the present invention, a keyword for an instant message can be extracted not only by the terminal 100 but also by the instant message server 110.
