Best Mode for Carrying Out the Invention

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily carry out the embodiments.

  A search system according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

  FIG. 1 is a block diagram for explaining a search system according to an embodiment of the present invention, and FIG. 2 is a block diagram showing an example of the search server shown in FIG.

  As shown in FIG. 1, a search system 100 according to an embodiment of the present invention includes a search server 110, a site catalog database 120, and a search database 130 that are connected to each other. The terminal 200 is connected to a plurality of websites 300.

  The user terminal 200 is a device that communicates with the search system 100 in order for a user to search the Internet, and exchanges information through the communication network 10. The user terminal 200 includes not only a desktop computer but also memory means such as a notebook personal computer, a workstation, a palmtop computer, a personal digital assistant (PDA), a web pad, and a microprocessor. This is a terminal device with computing power.

  The website 300 is a collection in which information is stored in a web server (not shown) so that information can be provided whenever a user needs information on the Internet. The search results can be voluntarily provided so that the user can find and use them more conveniently. The website 300 can be directly connected to the user terminal 200 through the communication network 10 to provide a search result. However, in the present invention, the search result can be provided through the search system 100.

  As the communication network 10, various network forms such as a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), and the Internet can be applied. The communication method may be any communication method regardless of wired or wireless.

  The site catalog database 120 stores a site catalog (site list) related to the website 300 that can independently provide search results. The site list includes a network address of each website 300 and at least one site-related word corresponding to each website 300. Here, the site-related word means a word related to a specific website 300, and the name of the website 300 or its synonym is used. As the network address of the website 300, a domain address or an IP address (internet protocol address) of the website 300 is used. For example, the website of Korea Broadcasting Corporation uses' Korea Broadcasting Corporation ',' KBS ',' KBS ',' Korea Broadcasting ', etc. as site related words, and' www. kbs. co. kr 'is used as the website network address.

  The site catalog is collected by a web robot (Web robot, not shown) that performs a function of automatically collecting information on the website 300 while periodically circulating on the web, or an operator of the search system 100. It is also possible to input directly to the site catalog database 120 by The web robot is implemented by software that searches for a website 300 that provides a search function on the web, collects the name and network address of the website 300, and stores the collected information in the site catalog database 120.

  The search database 130 stores information about various web pages collected on the web by a search robot (not shown). The web page information is organized and stored in a plurality of search catalogs (search lists) according to the criteria of the search system 100 itself. Each search list may include a title, a URL, a web page description, an index word, and the like. Here, the title is a name given to the web page, and the URL is a network address of the web page.

  As shown in FIG. 2, the search server 110 includes a search word analysis unit 112, first and second search units 114 and 116, and a search result providing unit 118, and displays a web page including a search window as a user terminal. The search word is provided to the machine 200, the search word is received from the user, and an appropriate search operation is performed on the search word, and then the search result is provided to the user. Note that at least one of the search word analysis unit 112, the first and second search units 114 and 116, and the search result providing unit 118 is located outside the search server 110, that is, the search server 110. It is also possible to configure such that it is included separately in a separate server (not shown).

  The search word analysis unit 112 analyzes the search word received from the user through parsing or the like. The search term analysis unit 112 determines whether or not there are a plurality of search terms. When a plurality of search terms are input, the search term analysis unit 112 queries the site catalog database 120 for each search term and selects a site from the plurality of search terms. Determine if there are related terms. When the search word analysis unit 112 determines that there is a site-related word among a plurality of search words, the search word excluding the site-related word from the plurality of search words (hereinafter referred to as “sub-search word”). ) And the network address of the website 300 are provided to the first search unit 114. In addition, the search word analysis unit 112 provides the received search word to the second search unit 116.

  The first search unit 114 refers to the network address received from the search word analysis unit 112 and connects to the website 300. Then, a sub search word is input to a search window included in the search page of the connected website 300 to make a search request for the sub search word, and the search result is received from the website 300. Thereafter, the search result provided from the website 300 is transmitted to the search result providing unit 118. The first search unit 114 and the website 300 can exchange data created by HTML (hypertext markup language) or XML (extensible markup language).

  For example, if the search word input from the user is 'KBS winter sonata', the search word analysis unit 112 parses the input search word into “KBS” and “winter sonata”. Separate and query the site catalog database 120 for each separated search term. Since 'KBS' is registered as a site-related word, the search word analyzing unit 112 uses the network address' www. kbs. co. kr ′ is extracted from the site catalog database 120 and transmitted to the first search unit 114 together with the sub-search term “winter sonata”. The first search unit 114 is a website of the Korea Broadcasting Corporation 300'www. kbs. co. Connect to kr 'and request a search result for' Winter Sonata 'and receive the search result.

  When the second search unit 116 receives a search term input by the user from the search term analysis unit 112, the second search unit 116 inquires the search database 130 and searches the search database 130 for an index that includes the received search term. Extract from Thereafter, the second search unit 116 provides the extracted search catalog to the search result providing unit 118 as a search result for the search term input by the user.

  The search result providing unit 118 receives the search results from the first and second search units 114 and 116, generates a web page including each search result by a predetermined method, and provides the web page to the user terminal 200.

  An example of a method in which the search result providing unit 118 generates a web page including the search result will be described with reference to FIG.

  FIG. 3 is a diagram illustrating an example of a web page provided as a search result in the search system according to the embodiment of the present invention, and illustrates a case where the user inputs 'KBS winter sonata' as a search term. ing.

  As shown in FIG. 3, the search result 420 received from the first search unit 114 is arranged at the top of the web page 400, and the search list 410 received from the second search unit 116 is arranged at the bottom of the web page 400. ing.

  The search result 420 is obtained from the Korea Broadcasting Corporation website 300'www. kbs. co. When the search term “winter sonata” is entered as a search term in the search window “kr”, the search result provided by the website 300 is substantially the same. The search result providing unit 118 can insert the search result 420 received from the website 300 into the web page 400 using the IF frame (inline frame) method. IFframe is an HTML component that allows other HTML documents to be inserted inside the main web document. The search result 420 inserted by the IF frame method is displayed and used by the user in the form provided by the website 300. Of course, the search result providing unit 118 can also provide the search result 420 after changing it according to the standard of the search result 420 itself. For example, a shortcut or a review button can be added to the search result 420, or contents can be added.

  On the other hand, FIG. 3 shows an example in which the search result 420 received from the first search unit 114 is arranged in the upper stage of the web page 400, but the arrangement position of the search result 420 can be changed as necessary. The search result 420 provided from the website 300 can be provided to the user by placing it at the bottom of the web page 400, or the search result 420 can be placed on the left or right side by dividing the web page 400 into left and right. it can.

  On the other hand, in the search terms input by the user, the order of the site-related terms and the sub-search terms is not related. In other words, the same search result can be provided to the user regardless of whether it is input using “KBS Winter Sonata” or “Winter Sonata KBS”.

  In addition, in order to provide a more accurate search result, a search method according to an embodiment of the present invention can be allowed for a predetermined sub-search word. For example, in order to provide 'Winter Sonata' by 'KBS', it is assumed that the user inputs the search term on the assumption that the content corresponding to the sub-search term is provided by the website 300 corresponding to the site related term. Is done. Therefore, if a word related to the content provided on the website 300 is registered in advance and the sub-search word input by the user corresponds to this, the same search operation in the embodiment of the present invention is performed. Search results can be provided to the user.

  In general, it is highly probable that the website 300 corresponding to the site-related word provides the content corresponding to the sub-search word, so that it may be assumed that the site-related word and the sub-search word have a very close relationship. it can. Therefore, when the user inputs search terms that are related to each other and site related terms are included in the search terms, it is preferable to provide the search result by the search system according to the embodiment of the present invention, which is suitable for the user's intention. And the user can enjoy more satisfaction with the search results.

  Next, the operation of the search system 100 according to the embodiment of the present invention will be described in more detail with reference to FIG.

  FIG. 4 is a flowchart for explaining the operation of the search system according to the embodiment of the present invention.

  First, when the operation is started and a search word is received from the user terminal 200 (S510), the search word analysis unit 112 analyzes the search word through parsing or the like (S520).

  The search term analysis unit 112 transmits the search term input by the user to the second search unit 116, and the second search unit 116 queries the search database 130 for the search term (S530). Step S530 can be performed at any time after the search term is received from the user until the search result is provided to the user, and does not significantly affect the overall operation.

  The search term analysis unit 112 determines whether or not there are a plurality of analyzed search terms (S540). If it is determined that a plurality of search terms are input, each search term is stored in the site catalog database 120. It is inquired to determine whether or not there is a site-related word among a plurality of search terms (S550).

  As a result of the determination, if there is a site related word among the search words, the network address and the sub search word corresponding to the site related word are transmitted to the first search unit 114. The first search unit 114 connects to the website 300 corresponding to the network address and makes a search request for the sub-search word (S560), and then receives search results from the website 300 (S570). If it is determined in step S540 that there are not a plurality of search terms, or if it is determined in step S550 that there are no site-related terms in the search terms, the first search unit 114 makes a search request to the external website 300. Processing is omitted.

  The search result providing unit 118 receives the search results from the first and second search units 114 and 116, generates a web page including the search results by a predetermined method, and provides the web page to the user terminal 200 (S580). Here, when the search result providing unit 118 does not receive the search result from the first search unit 114, the search result providing unit 118 generates a web page using only the search result of the second search unit 116 and provides the web page to the user terminal 200. .
