Referring to FIG. 3, a server 140 in which a search related function according to the present invention may be performed may include a web information storage device 310, a related word detector 320, and a web search engine 330. Each server component is separated by function, not physically. Thus, each server component may consist of one or more server entities described above in FIG. 2, and two or more server components may be implemented by one server entity.

Hereinafter, the function of each component is demonstrated.

First, the web information storage device 310 analyzes web documents existing on the Internet to search for a web document for finding a web document that matches a user's search query, and to search for a given web document. Performs the function of extracting and storing information needed to find related related words. Extraction and storage functions may be performed periodically or continuously.

Here, the related word refers to a keyword that is related to a search word input by a user. In this case, the relevant keyword is simply a keyword including at least some of the morphemes constituting the search term, a keyword appearing together on arbitrary webpages in which the search word appears, or a keyword appearing in a document linked to the search word in any webpage. The concept includes such. The concept of correlation described above is exemplary, and in addition, various criteria may be applied to the determination of correlation. Hereinafter, in the present specification, "related words", "related keywords", "associated keyword", and "associated keyword" are considered to have the same meaning.

In order to obtain information necessary for searching a web document, the web information storage device 310 analyzes an arbitrary web document, extracts words included in the web document, and constructs an index indicating a web document including the extracted words. . In addition, in order to obtain the information necessary to find related words related to a given search word, the web information storage device 310, according to the association between the web document via the link, keywords accompanying the link to another web page (hereinafter referred to as "link- And an association of the web document indicated by the link-keyword.

Next, the related word detector 320 analyzes a search word input from a user and detects a related word related to the input search word by using information necessary for searching a web document stored in the web information storage device 310 and information needed to find a related word. It performs the function.

In addition, the web search engine 330 may search for a general web document of a search word input by a user and a related word detected by the related word detector 320 (that is, an address and / or content of a web page including the corresponding search word or related word). Performs the function of outputting.

The server 140 including the above-described components may provide information for configuring a relationship diagram to be displayed on the user terminal 110. If the user combines the new search terms using the relationship diagram user interface 350, the server 140 may detect the related word for the new search term and provide information for updating the relationship diagram back to the user terminal. . Here, the relationship diagram user interface 350 refers to a user interface for using or manipulating a relationship diagram showing a relationship between a search word and a related word for the search word according to a predetermined rule. The relational user interface 350 may be implemented using hypertext (HTML), Flash, Java applet, or the like in a general web browser, or may be implemented using a predetermined dedicated application. The relationship diagram may have a form in which a search word input by a user is arranged at the center and related words detected around the arrangement are arranged according to a predetermined rule. The form of a more specific relationship diagram is mentioned later.

Process of performing a search

Hereinafter, a method of searching for a related word using a relationship diagram according to the present invention that may be performed in the system described with reference to FIGS. 1 to 3 will be described in detail with reference to FIG. 4.

4 is a flowchart illustrating an example of a related word search method using a relationship diagram according to an exemplary embodiment of the present invention.

Before describing the related term search method illustrated in FIG. 4, information necessary for searching a web document and information needed to find a related term have already been acquired in the web information storage device 310 of the server 140 described with reference to FIG. 3. Assume that it is saved.

First, a search word may be input from the user (S401).

To this end, when a user selects a word for which he / she wants to obtain information through the user terminal 110 and inputs a search word, the user terminal 110 sends the input search word to the search server 140 through the communication network 130. I can deliver it.

The search server 140 may detect a related keyword, that is, a related word, using the search word input from the user (S402).

To this end, the associated word detection unit 320 of the search server 140 may use the information stored in the web information storage device (310). In addition, the web search engine may search a web page for a search word or a related related word using information stored in the web information storage device 310.

The detected related word and the retrieved web page may be transmitted to the user terminal 110 through the communication network 130. The user terminal 110 may generate and display the relationship diagram through the relationship diagram user interface 350 using the received information (S403).

Here, the degree of association of the related words with the search word, that is, the degree of association may be taken into account in the generation of the relationship diagram. The degree of association may be measured by the related word detection unit 320 of the search server 140. The criteria for ranking related words may be related to the morpheme similar to the search word and the related word may appear in the web page including the search word. Frequency of the related words may be included in the webpage pointed to by the link of the webpage including the search word. This degree of association may be represented by the size of an area where each related word is displayed in the relationship diagram.

When the relationship diagram is displayed through the relationship diagram user interface 350 in the user terminal 110, the user may manipulate the relationship diagram user interface to generate a new search term by combining at least a portion of the search word and the related word (S404). A detailed view of generating a new search word by manipulating the relational user interface 350 will be described later.

When a new search word is generated, the user terminal 110 transmits the new search word to the search server 140 again. The search server may detect a related word for the new search word through an operation similar to the above-described step S402 (S405). In this case, the web search engine of the search server 140 may search for a new search word and a web page corresponding to the related word.

The search server 140 may transmit information about the detected related word and the searched web page to the user terminal 110. The user terminal 110 may update the relevance on the relevance user interface 350 using the received information (S406). In this case, the user terminal 110 may update the related word in consideration of the degree of association with the new search word of the detected related word.

The user may continue to combine the search terms by manipulating the relational user interface 350 until a desired search result is obtained (S407).

Relationship diagram user interface

Hereinafter, a form of a relationship diagram and a method of combining a new search word that can be applied to a relationship diagram user interface will be described with reference to FIGS. 5A to 8.

First, the specific form of the relationship diagram will be described with reference to FIGS. 5A and 5B.

5A illustrates an example of an initial screen of a relationship diagram displayed on a user terminal as an embodiment of the present invention.

Referring to FIG. 5A, a relationship diagram region 10 is located on one side of a screen. The search term region 20 is located at the center of the relational region 10, and the region except for the search term region 20 is the related region 30 in the relational region 10. In the search word area 20, a user may directly input a search word 21 to be searched. If a separate search word input area (not shown) for inputting a search word is provided in a portion of the screen, the user may enter a search word in the separate search word input area.

Below the relational area 10, a keyword area 40 may be located to store at least one of the input search word, related word and related word. In other words, the keyword is a concept that includes all of the words stemmed from them so that the keyword and related words and search word recombination can be freed more. Here, the term morphologically analyzed refers to a word that is separated and / or recombined when the search word or related word is composed of two or more morphemes (minimum units having independent meanings).

The keyword area 40 may display at least one of a search word displayed in the current search word area 20, a related word and a related word, and a search word combined from the beginning to the present point of time and all related words searched for the related word. May be displayed. In addition to the related words displayed in the related word area 30, words obtained by stemming the search word, related words, and related words displayed in the keyword area 40 may also be used in the combination of the new search words.

In addition, the webpage information area 50 displaying a webpage search result for a search word input by a user and / or a related word may be located on another side of the screen.

Referring to FIG. 5B, a result screen of searching for a related word for the search word 21 displayed in the search word area 20 in the above-described relationship diagram will be described.

5B illustrates an example of a search result screen of a relationship diagram user interface displayed on a user terminal according to one embodiment of the present invention.

Referring to FIG. 5B, related words for the search term “google” 21 may be radially connected to the search word area 20 in a line in the related word area 30. Each related word may have a figure indicating a degree of association with a search word in its vicinity. In this case, the size of the figure may correspond to the size of the degree of association. Although the figure is shown in a circle in FIG. 5B, this is an example and may be replaced with other various shapes (eg, polygons). Accordingly, the user can easily recognize that the related words such as "Google" 31, "Larry Page" 32, and "Sergey Brin" 33 are most relevant in the size of the circle.

On the other hand, a number, graph, color, or a combination thereof, rather than the size of the figure, may be used as a method for indicating the size of the association degree.

In the keyword area 40, a keyword (a search word, a related word of the search word, and a related word of the search word) may be displayed in a list form. If a keyword is not large enough to be displayed all at once in the predetermined keyword area 40, it may occur. In this case, only as many keywords as can be displayed at a time are displayed in the predetermined keyword area 40, and the remaining keywords are displayed as the scroll buttons (arrow buttons) located at both edges of the keyword area 40 are operated by the user. Can be displayed.

In addition, the webpage information area 50 displays a webpage search result for the related word. In the search results of a webpage, the definition, dictionary meaning, or brief description of the related word is displayed first, and when the relevant word is selected, more detailed webpage information is displayed along with the link, address, and / or contents of the webpage. Can be. The order in which the web page search results for related words are displayed may be in the order of high correlation to low order.

Next, a specific form in which a search word and a related word are combined will be described with reference to FIGS. 6A to 7.

6A illustrates an example of a search word and a related word combined in a relation diagram according to an embodiment of the present invention.

Referring to FIG. 6A, when both the keyword 03 (34) and the keyword 02 (42) displayed in the keyword area 40 are selected among the related words displayed in the related word area 30, the search word area 20 includes an existing search word, The keyword 02 (42) and the keyword 03 (34) may be combined to generate a new search word. In order to select a related word for combination, a user may use a method of clicking or double-clicking a keyword displayed in the related word or keyword area 40 of the related word area 30 using a cursor. In addition, a method of dragging and dropping each related word to the search word area 20 may be used. On the contrary, the search word input by the user in the search word area 20 or the related words added for the combination may be excluded from the search word area 20 through the above-described click, double click, or drag & drop operation. have.

The operation of updating the relationship diagram by detecting the related words for the newly generated search word (steps S405 and S406) is performed whenever the related word is added to or excluded from the search word area 20 by the user, that is, the contents of the search word area 20. This can be done whenever it changes. Alternatively, the update combination execution icon 600 of the relationship diagram may be provided. In this case, at the moment when the combination execution icon 600 is selected (or manipulated) by the user regardless of the change in the search word area 20, the keywords existing in the search word area 20 become new search terms and related terms are detected. The relationship diagram may be updated.

Meanwhile, the user terminal 110 may include a touch screen that recognizes a user's touch or proximity touch input as well as a display function. The touch screen can be operated by various principles. In general, a resistive method that recognizes a change in resistance value of the resistive film due to pressure applied to the touch screen or a capacitive method that recognizes a change in capacitance by touch on the touch screen is used. Can be used.

Touch screens are widely used as command input means of mobile terminals such as mobile phones or PDAs as well as fixed terminals. In addition, the touch screen may be provided with a multi-touch function for distinguishing and recognizing touch inputs to two or more points at the same time. The relationship in the case where such a touch screen is provided in the user terminal will be described with reference to FIG. 6B.

6B illustrates an example of combining a search word and related words in a touch screen environment according to an embodiment of the present invention.

In FIG. 6B, the keyword 03 34 of the related area 30 and the keyword 02 42 of the keyword area 40 are combined in the search word area 20 to form a new search word. Assume

In this case, each keyword may be included in the search word area 20 by dragging and dropping by fingers 610 and 620 on the touch screen. If the touch screen includes a multi-touch function, the user may touch two or more points at the same time to include a plurality of related words in the search word area 20. That is, one finger 610 may include the keyword 02 42 in the search word area 20 and the other finger 620 may include the keyword 03 34 in the search word area 20 at the same time. . This allows the user to combine new search words more conveniently and quickly.

Meanwhile, in embodiments of the present invention, a related word for a search word input by a user may be composed of one or more morphemes. If a user intends to use only a morpheme of a related word composed of a plurality of morphemes to combine a new search word, a method for conveniently and efficiently selecting only a morpheme from a relational diagram is required. This will be described with reference to FIG. 7.

FIG. 7 illustrates an example of a method of selectively using a part of a plurality of morphemes constituting a keyword in a combination of a new search word according to an embodiment of the present invention.

In FIG. 7, it is assumed that two related words 34 and 35 are displayed in a related word area as a result of a search word 22 input by a user. At this time, it is assumed that keyword 2 35 is composed of one morpheme 705, and keyword 1 34 is composed of two morphemes (keyword 1A 701 and keyword 1B 702).

Here, the combination shortcut button may be used to select a part of the related word to be combined to combine the new search word. When the combination shortcut button is selected through a user's touch or cursor operation according to the type of the input means of the user terminal 110, a search term region (or a morpheme of a related word corresponding to the selected combination shortcut button is directly combined). 20) can be added. In addition, the combination shortcut button may be provided for each morpheme or each related word.

For example, even if only one of the combination shortcut button 715 of the morpheme level and the combination shortcut button 725 of the related word level is provided for the related word composed of one morpheme 705 such as keyword 2 35, the keyword is provided. There is no problem in selecting 2 (35).

By the way, in the case of the keyword 1 (34), the user may use the entire keyword 1 (34) for generating a new search word, but it may be more efficient to use only some morphemes (701). In this case, the user may add the keyword 1A 701 to the search word region 20 by selecting the combination shortcut button 711 of the morpheme level corresponding to the stemming keyword 1A 701. If the user wants to add the entire keyword 1 34 to the search word area 20, the user may select the shortcut 720 of the related word level.

The name, shape, and location of the combination shortcut button described above are exemplary, and the name, shape, and location of the combination shortcut button may be changed into various forms as necessary. In addition, even when the above-described combination shortcut button is provided in the relational user interface, drag and drop manipulation using a cursor and / or drag and drop manipulation using a touch (multi-touch) may be combined and applied simultaneously. .

Referring to FIG. 8, a process of searching for a desired keyword through a combination of search terms will be described with reference to FIG. 8.

In FIG. 8, one wonders what happens when a user catches swine flu, but when the user does not know the exact search word for this, the relationship diagram according to the present invention illustrates a process of searching for the correct search word using the user interface.

First, referring to FIG. 8A, the user first enters the flu 800 into the search word region 20. As a result, 'bird's flu', 'swine flu', 'bird flu', 'AI' and 'bird flu prevention' are detected and related to the flu. The user may generate a new search term by selecting and combining the morphemes closest to the subject to be searched from the related words displayed in the relationship diagram. For that purpose, the user may select the stem from the related 'swine flu' and the stem from the related 'sick flu symptoms'. As a method of selecting each morpheme, the methods described with reference to FIGS. 6A to 7 may be selected or used in combination. As described above, the user may conveniently combine more accurate search terms by receiving information for generating an accurate search word desired by the relationship diagram user interface.

As a result of the search word combination, as shown in FIG. 8B, the newly combined search word 'Swine Flu Symptoms' 801 is displayed in the search word area 20, and related words are displayed in the vicinity thereof. Accordingly, the user can obtain related words related to swine flu symptoms such as helplessness, high fever, diarrhea, vomiting or the like, or can additionally and easily search for preventive methods for preventing such symptoms. Of course, although not shown, the user may also obtain additional information about each related word through the information displayed in the webpage information area 50.

Further, according to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.

The invention can be embodied in other specific forms without departing from the spirit and essential features of the invention. Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention. In addition, the claims may be combined to form an embodiment by combining claims that do not have an explicit citation relationship or may be incorporated as new claims by post-application correction.
