The 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 containing one or more instant messages. At this time, the chat room may be created by an instant messaging service or an application providing an instant messaging service installed in the terminal. The terminal user can exchange instant messages with the users of one or more other terminals through the chat room created in the terminal 100.

The terminal 100 extracts one or more keywords from one or more instant messages to generate a search page and displays the generated search page as the interaction of the terminal user is input in the chat window in which the chat room is displayed.

When the terminal user selects one of the keywords on the displayed search page, the terminal 100 delivers the keyword selected by the terminal user to the instant message server 110 and receives the search result from the instant message server 110 . In addition, the terminal 100 generates a search result page including the received search result, and displays a search result page. At this time, the search result for the selected keyword may be the search result received from the search server 120 by the instant message server 110.

The instant message server 110 delivers the instant message transmitted by the terminal 100 to another terminal. The instant message server 110 generates a query including the keyword transmitted by the terminal 100 and transmits the query to the search server 120. Upon receiving the search result for the query generated by the search server 120, (100).

The search server 120 receives a query for the 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. The search server 120 transmits the search result to the instant message server 110 to transmit the search result to the terminal 100.

At this time, the instant message server 110 and the search server 120 may be separated from each other and run on independent server computers, or they may be installed as server programs on the same server computer, respectively. In addition, the search server 120 may be an external search server connected to the instant message server 110 through a network or a portal providing a search service.

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

Specifically, the terminal 100 included in the keyword search system 10 displays a chat window containing one or more instant messages in the chat room. The terminal 100 extracts one or more keywords from one or more instant messages included in the chat room when an interaction of the terminal user who intends to search keywords is input using the instant message.

At this time, the instant message from which the keyword is extracted may be an instant message included in the chat window in which the chat room is displayed. In addition, the instant message from which the keyword is extracted may be an instant message included in a predefined search range.

The terminal 100 may extract one or more keywords from the instant message based on the pre-stored search index list. At this time, the pre-stored search index list may be one in which the keyword extracted by the terminal 100 is indexed and stored. In addition, the pre-stored search index list may include a search index list received from the instant message server 110.

In addition, the terminal 100 can extract a keyword by parsing an instant message. At this time, the terminal 100 extracts one or more words by parsing the instant message, and extracts one or more keywords from the extracted one or more words based on a text mining technique.

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

The instant message server 110 receiving the keyword selected by the user from the terminal 100 generates a query including the received keyword and transmits it to the search server 120. The search server 120 receiving the query performs a search for the query and transmits 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. The instant message server 110 transmits the search result received from the search server 120 to the terminal 100.

Upon receiving the search result from the instant message server 110, the terminal 100 displays a search result page corresponding to the selected keyword on the displayed chat window. Therefore, the terminal user can confirm the search result for the desired keyword on the search result page of the terminal 100. [ The terminal user can return 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. [

Meanwhile, the terminal 100 may separately display a keyword, which is determined by the terminal user from among the one or more keywords included in the search page, to be different from the keywords of the other instant messages. In addition, the terminal 100 may include an indicator that distinguishes the speech balloon on which the instant message including the keyword is displayed among the instant messages included in the chat room.

When the terminal user confirms the search result, the keyword that confirmed the search result is separately displayed so as to be differentiated from other instant messages. When the terminal 100 receives an input for selecting a keyword displayed so as to be differentiated from the terminal user, A search result page can be provided. At this time, the terminal 100 according to an embodiment of the present invention not only provides a search result page by clicking a keyword displayed to discriminate a keyword on an instant message included in a speech bubble area, but also selects a speech bubble area You can also provide a search results page if you select the "Search Results" tab on the pop-up menu provided through the input.

In addition, when displaying one or more keywords included in a search page, the terminal 100 according to an embodiment of the present invention may search for keywords that have already confirmed the search results, You can add a differentiation to the keywords you've seen.

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

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

The terminal 100 according to an exemplary 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.

Display module 200 displays a chat room containing one or more instant messages.

The memory 210 stores a keyword search program. Here, the memory 210 is collectively referred to as a non-volatile storage device that keeps stored information even when power is not supplied, 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.

Also, the input module 240 can receive the interaction of the terminal user. At this time, 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 touch screen panel such as a resistive type or a capacitive type, and may be integrated with the display module 210.

The processor 220 in accordance with one embodiment of the present invention displays a chat room containing one or more instant messages via the display module 200. Further, the processor 220 executes the keyword search program stored in the memory 210. [

When a terminal user enters an interaction within the chat window in which the chat room is displayed, 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.

At this time, the instant message from which the keyword is extracted may be an instant message included in the chat window in which the chat room is displayed. In addition, the instant message from which the keyword is extracted may be an instant message included in a predetermined search range such as the number, date, and time. For example, if the predetermined search range is a predetermined number, the instant message to be extracted may be 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. In addition, the predetermined search range may be set in the instant message server 110 and transmitted to the terminal 100. The predetermined search range can be set according to the size of the interaction that the terminal user inputs into the chat window.

In addition, the predetermined search range may be a specific location or place. For example, if the predetermined search range is the current location, the processor 220 may extract the keyword for the instant message generated at the current location. If the predetermined search range is "Seoul ", the processor 220 can extract the keyword for the instant message sent by the terminal user in" Seoul ".

At this time, the terminal 100 may include a position sensor 250 for measuring the position. At this time, the position sensor 250 may include at least one sensor for measuring a position of a global positioning system (GPS) and a geomagnetic 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 according to information collected by a communication device such as an access point and a base station connected to the communication module 230.

Meanwhile, the interaction of the terminal user can be inputted through the input module 240. [ For example, the interaction may include clicking, tapping, drag and drop, swipe, pinch in / out, / out < / RTI > and flick. If the input module 240 is a touch panel supporting multi-touch, the terminal user can input the interaction using a tool such as a finger or a touch fan.

Pinch in / out means that the terminal user touches the input module 240 using two fingers and then opens or closes the fingers while maintaining the touch. In this case, when two fingers are opened, it is called a pinch-out, and when two fingers are closed, it is called a pinch-in.

In addition, 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 managing the chat room.

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

3 is an exemplary diagram of a chat window and a search page according to an embodiment of the present invention.

When the terminal user inputs the interaction 310 in the chat window P300 displayed on the display module 200, the processor 220 selects one or more instant messages P301 to P307 included in the chat room corresponding to the inputted interaction Extract one or more keywords. At this time, the instant message from which the keyword is extracted may include the instant messages P301 and P306 input by the terminal user and the instant messages P302 through P305 and P307 transmitted by the conversation partner participating in the chat room.

Processor 220 may extract keywords from one or more instant messages P301 through P307 based on the search index list. At this time, the search index list may be one in which the keyword extracted by the processor 220 is indexed and stored in the memory 210. In addition, the search index list may include a search index list received from the instant message server 110 via the communication module 230. The processor 220 receives a new search index list from the instant message server 110 through the communication module 230 and transmits the received search index list to the search index list stored in the memory 210 . ≪ / RTI >

For example, the processor 220 receives a search index list including keywords frequently searched from the search server 120 by the other terminal from the instant message server 110 through the communication module 230, ) To the search index list stored in the database. The processor 220 may receive the search index list including the keywords extracted by the other terminals through the communication module 230 and may add the search index list to the search index list stored in the memory 210. The processor 220 may receive the new search index list including the keyword and the issue keyword from the instant message server 110 through the communication module 230 and add the new search index list to the search index list stored in the memory 210.

The processor 220 may calculate the similarity between one or more keywords included in the search index list and an instant message to extract the keyword. The processor 220 may extract the keyword based on the calculated similarity. Processor 220 may generate a search page that includes the extracted keywords. Accordingly, the extracted keyword can be exposed to the terminal user through the search page.

At this time, the processor 220 may generate the search page by sorting the keywords in ascending or descending order in order of the degree of similarity among the plurality of keywords. For example, the similarity measure is not only a measure of similarity between two texts, such as cosine similarity, Jaccard index, Spearman's similarity, and Dice's coefficient, But are not limited to, scales used in information retrieval such as TF-IDF (term frequency-inverse document frequency) and page rank.

In addition to extracting the keyword based on the search index list, the processor 220 may extract the keyword by parsing the instant message to extract the keyword. At this time, the processor 200 can perform a parsing based on the morpheme analyzer to extract a plurality of words from the instant message.

The processor 200 can extract one or more keywords from a plurality of words extracted based on the text mining technique when a plurality of words are extracted through parsing. At this time, the text mining technique extracts meaningful data from unstructured text based on natural language processing, machine learning and statistical techniques.

For example, the processor 200 may extract keywords based on the number of occurrences in the chat room for a plurality of words. In addition, the processor 200 may measure a score for a plurality of words and extract keywords based on the measured scores. At this time, the score may be entropy, chi-square statistic, TF-IDF, page rank, and the like.

The processor 200 may extract a word having a meaning among a plurality of extracted words as a keyword. For example, the processor 200 may extract a word indicating a place or a position among the extracted words as a keyword. In addition, the processor 200 may extract a key word in a context or extract a keyword by analyzing an opinion included in the context.

Referring again to Figure 3, for example, the processor 220 may determine whether the instant message (P301 through P307) displayed in the chat window 300 displayed on the display module 200 is based on a comparison or parsing with a search index list Four keywords P321 to P324 can be extracted. The processor 220 may generate the search page 320 by sorting the extracted four keywords P321 to P324.

At this time, the processor 220 displays a "search word input window" or a "search button ", which allows the terminal user to search for a desired keyword on the search page when there is no keyword extracted from the instant message, Can be added. For example, when the terminal user directly inputs a keyword into the "search word input window ", the processor 220 can transmit the input keyword to the instant message server 110 through the communication module and receive the search result. When the terminal user inputs an interaction for selecting the "search button ", the processor 220 provides an external application such as an application corresponding to the search server 120 and a web browser, etc. so that the terminal user can search for the keyword can do.

Meanwhile, the processor 220 extracts a keyword, and then provides a search page including the extracted keyword to the terminal user through the display module 200. When the terminal user selects one of the extracted keywords, the processor 220 can transmit the selected keyword to the instant message server 110 through the communication module 230.

The instant message server 110 receiving the selected keyword can generate a query including the extracted keyword. And the instant message server 110 may send the generated query to the search server 120. [

Upon receiving the query, the search server 120 may perform a search on the query to generate a search result for the selected keyword. The search server 120 may transmit the generated search result to the instant message server 110.

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

In addition, the instant message server 110 may generate a search result page including the received search result, and may transmit the generated search result page to the terminal 100. At this time, the processor 220 receiving the search result page through the communication module 230 can display 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 in the form of an instant message as well as being provided in the form of a search page.

Meanwhile, according to the size of the display module 200, the processor 220 can generate a search result page including only a part of the search results for the keyword that the terminal user desires to search. That is, the search result page may be a list of search results having a high degree of similarity among the search results for the keywords that the terminal user wants to search. Therefore, the processor 220 may provide a next search result confirmation menu or button so that the search result not included in the search result page can be confirmed.

For example, if the processor 220 has received ten search results but can display four search results at a time on the display module 200, the processor 220 may search four search results And generate a search result page including the extracted four search results. At this time, the search result page may include a "confirm next search result" button to confirm the remaining six search results. The processor 220 may then display the generated search result page on the display 200 module.

If the terminal user selects the " confirm next search result "button, the processor 220 generates a search result page including the four search results in descending order of similarity among the remaining six search results, As shown in FIG. At this time, the search result page may include a "previous search result confirmation" button for confirming the previously displayed four search results and a "next search result confirmation" 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 sends a web viewer, which can confirm the through search results including all ten search results, .

Meanwhile, when the terminal user selects one of the search results included in the search result page, the processor 220 can provide detailed information on the selected search result. At this time, the processor 220 may provide a web viewer to provide detailed information. In addition, the processor 220 may provide detailed information through an external application such as the search server 120 and a corresponding web browser, or the like.

After the terminal user confirms the search result, the processor 220 may provide the search result page with a return menu or a return button so that the terminal user can return to the chat room. If the terminal user selects the return menu or the return button, the processor 220 may close the search results page and display the chat room.

On the other hand, the processor 220 can display the keyword extracted from the instant message so that the terminal user can distinguish the keyword from the keyword that has not confirmed the search result. For example, the differentiation could be to change the font to a different font than the keyword of the keywords included in the search page. In addition, the differentiation may be to change the attributes of the fonts contained in the search results page. At this time, the attributes of the font may be underscores, beeps, highlights, and markers.

In addition, the processor 220 may separately display a keyword for which the terminal user included in the at least one instant message included in the chat room confirmed the search result, so as to be different from the keyword of the other instant messages. For example, when the terminal user confirms the search result, the processor 220 may change the font, change the underline, and / or the font so that the instant message containing the keyword or the keyword is different from the instant message or keyword included in the chat room, Highlights and marker lights can be added for display. In addition, the processor 220 may include an indication to distinguish the speech balloon on which the instant message including the keyword that the terminal user confirmed the search result is displayed among the instant messages included in the chat room.

When the terminal user inputs an interaction for selecting a keyword, an instant message, or a speech balloon including an indication to discriminate, the processor 220 can display a corresponding search result page. Alternatively, the processor 220 may display a pop-up menu that includes a "search results" menu that can display the corresponding search results page. If the terminal user selects "search result" from the pop-up menu, the processor 220 can display the search result page.

In addition, when displaying one or more keywords included in the search page, the processor 220 may display a keyword different from the keyword that has confirmed the search result for distinguishing the keyword that the terminal user has already confirmed the search result and the keyword that has not confirmed the search result Can be added. The processor 220 may then display on the search page a keyword that contains a distinctive indication. The terminal user can distinguish between the keyword that has already confirmed the search result and the keyword that has not confirmed the search result through the search result page including the keyword marked to be discriminated in this manner.

The terminal 100 according to an embodiment of the present invention can quickly and easily search for keywords included in the instant message according to the interaction inputted through the input module 240 without ending the chat room. Hereinafter, keyword search of the terminal 100 according to an embodiment of the present invention will be described with reference to FIG. 3 and FIG. 4. FIG.

4 is a diagram illustrating an example of keyword search in a conventional terminal.

4, when searching for a keyword included in an instant message while exchanging an instant message in a chat window, the conventional terminal displays a menu window 410 provided by the operating system of the conventional terminal in the chat window 400 To the menu window 410 via the input P400. The terminal user can execute a search application or a web browser application in the menu window 410 and perform a search by directly inputting a keyword through a search application 420 or a search window 420 of a web browser (P420). After checking the search result 430, the terminal user may switch back to the chat window or re-execute the application providing the chat window to return to the chat window.

3, in an embodiment of the present invention, when a terminal user inputs an interaction (P310) in a chat window 300, the processor 220 may provide a search page from which a keyword can be selected . When the terminal user selects a keyword on the search page, the processor 220 can display the search result page including the search result of the selected keyword in the display module 200. [ The terminal user can return to the chat window 300 by confirming the search result through the search result page and closing the window where the search result page is displayed.

On the other hand, when the terminal user inputs the interaction, the processor 220 can extract the keyword from the instant message meeting the predetermined condition. At this time, the preset condition may be one or more instant messages displayed in the chat window through the display module 200. [ The processor 220 can extract keywords from the one or more instant messages displayed in the chat window through the display module 200. At this time, the interaction may be, for example, a pinch-out.

In addition, the preset condition may be an instant message included in a preset time range. The processor 220 may extract the keyword from the instant message included in the preset time range. For example, if the preset time is one hour, the processor 220 extracts an instant message from the instant message included in the chat room one hour before the input of the interaction, and extracts the keyword from the extracted instant message have.

The predetermined condition may be a search range set according to the input size of the interaction input by the terminal user. The processor 220 can set the search range according to the input size of the interaction input by the terminal user in the display module 200. [ The processor 220 may extract the keyword from the instant message included in the set search range.

At this time, the search range may be the date or time at which the instant message was generated. In addition, the search range may be the number of keywords extracted from the instant message. The search range may be preset or 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 according to the input size of the interaction of the terminal user will be described with reference to FIG.

5 is an exemplary view of a search range set according to the size of an interaction according to an embodiment of the present invention.

5 (a), when a terminal user inputs a pinch-out interaction, an interaction in a range corresponding to the innermost circle P500 smaller than that of Figs. 5 (a) and 5 (b) , The processor 220 can set the search range to be smaller than that of FIGS. 5 (b) and 5 (c) according to the preset search range. 5 (c), when the terminal user inputs a wider range of interactions than those shown in Figs. 5 (a) and 5 (b) like the outermost circle P520, the processor 220 The search range can be set to be larger than (a) and (b) in accordance with the preset search range.

For example, in the case where the search range is set so as to vary the date according to the length of the pinch-out interaction, the processor 220 determines whether the terminal user selects the search range b), the processor 220 can set the search range to one day according to the length (P500) of the input pinch-out. Therefore, the processor 220 can extract the keyword from the instant message generated from the moment when the terminal user inputs the interaction to the day before.

5 (b), if the terminal user inputs an interaction of a size corresponding to the second inner circle P510, the processor 220 can set the search range to two days. Therefore, the processor 220 can extract keywords based on the length P510 of the input pinch-out with respect to the instant message generated from the moment when the terminal user inputs the interaction two days before.

5C, when the terminal user inputs an interaction of about the third inner circle size P520, the processor 220 sets the search range to three days in accordance with the length P520 of the pinch-out . Therefore, the processor 220 can extract the keyword from the instant message generated from the time when the terminal user inputs the interaction to three days before.

The processor 220 according to an embodiment of the present invention adds one or more keywords from an instant message that is not included in the search range of the instant messages included in the chat room and has not been extracted when the terminal user inputs the interaction on the search page . At this time, the search range may be an instant message generated according to at least one of the instant message displayed on the display screen in the chat window and the preset time, date, and location, as described above.

For example, if the search range is an instant message of less than one hour, the processor 220 may extract the keyword based on the instant message within one hour, and display the search page generated by the extracted keyword. When the terminal user inputs the interaction on the search page, the processor 220 can further extract the keyword for the instant message not included in the search range. The processor 220 may then generate and display a search page containing the searched keywords.

The processor 220 may then display the extracted keyword on the search page. At this time, the interaction may be scrolling, for example. This will be described by taking Fig. 6 as an example.

6 is a diagram for explaining a method of searching for a keyword through an interaction on a search page according to an embodiment of the present invention

If the search range is the currently displayed instant message in the chat window, the processor 220 may extract one or more keywords from the currently displayed instant message as shown in FIG. 6 (a). If the terminal user inputs the interaction on the search page as shown in FIG. 6A, the processor 220 can re-extract the keyword from the instant message in which the keyword is not extracted because it is outside the search range. Then, the processor 220 can display the re-extracted keyword on the search page as shown in FIG. 6 (b).

At this time, the instant message in which the keyword is not extracted may be an instant message generated before the instant in which the keyword is extracted from the instant message included in the chat room. In addition, the instant message in which the keyword is not extracted may be an instant message generated later than the instant message reflected on the search result page.

Meanwhile, when the terminal user inputs the interaction in the chat window in which the chat room is displayed, the processor 220 can generate and display a search page including the keyword previously searched by the terminal user in the chat room. For example, if a terminal user enters an interaction in a chat window displayed with a chat room, the processor 220 may generate a search page containing a pre-search keyword previously searched by the terminal user in the chat room. The processor 220 may then display a search page containing the pre-search keyword.

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

Meanwhile, the processor 220 may display a predetermined number of keywords on the search page displayed on the display module 200. Therefore, the terminal user can input an interaction to confirm a keyword exceeding a preset number on the search page. For example, when the terminal user inputs an interaction for confirming the next keyword on the search page, the processor 220 extracts a keyword that exceeds the preset number of keywords extracted from the instant message included in the chat room and is not included in the search page And displays the generated search page on the display module 200.

Meanwhile, an embodiment of the present invention can extract a keyword for an instant message in the instant message server 110 as well as the terminal 100. [ The instant message server 110 according to an embodiment of the present invention will be described with reference to FIG.
