DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

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

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

Referring to FIG. 1, a search system 100 according to an exemplary embodiment of the present invention includes a search server 110, a site list database 120, and a search database 130 connected to each other, and a communication network 10. The plurality of user terminals 200 and the plurality of web sites 300 are connected to each other.

The user terminal 200 is a device in which a user communicates with the search system 100 to search the Internet, and exchanges information through the communication network 10. The user terminal 200 is provided with memory means such as a laptop computer, a workstation, a palmtop computer, a personal digital assistant (PDA), a web pad, etc., as well as a desktop computer, and has a microprocessor. It may be made of a terminal equipped with.

The web site 300 is a collection of information stored in a web server (not shown) so that users can provide it whenever they need the information on the Internet, so that the user can find and use the information more conveniently. May provide search results. Although the web site 300 may be directly connected to the user terminal 200 through the communication network 10 to provide a search result, the web site 300 may provide a search result through the search system 100.

The communication network 10 does not select a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), the Internet, or the like, and the communication method is wired or wireless. It doesn't matter what type of communication you have.

Site list database 120 stores a list of sites associated with web site 300 that can provide search results on its own. The site list includes a network address of each web site 300 and at least one site related word corresponding to each web site 300. Here, the site related word refers to a word related to a specific web site 300, and the name of the web site 300 or synonyms thereof may be used, and the web site network address may be a domain address or an IP address of the web site 300. (internet protocol address) may be used. For example, the website of Korea Broadcasting Corporation may include 'Korea Broadcasting Corporation', 'KBS', 'KBI's,' Korea Broadcasting ', etc., and' www.kbs.co.kr ' Can be used as a network address.

The site list is collected by a web robot (not shown) or by an operator of the search system 100, which performs a function of automatically collecting information of the website 300 while periodically circulating on the web. It may also be entered directly into the site list database 120. The web robot may be implemented by software that finds a web site 300 that provides a search function on the web, collects the name and network address of the web site 300, and stores the name in the site list database 120.

The search database 130 stores information on various web pages collected on the web by a search robot (not shown). The web page information may be organized and stored in a plurality of search lists based on its own criteria of the search system 100. Each search list may include a title, a URL, a description of the web page, and an index word. Where the title is the name given for the web page and the URL is the network address of the web page.

Referring to FIG. 2, the search server 110 includes a search term analyzing unit 112, first and second search units 114 and 116, and a search result providing unit 118, and includes a search page. Is provided to the user terminal 200 to receive a search word from the user, perform an appropriate search operation on the search word, and provide the search result to the user.

The search term analyzing unit 112 analyzes the search term received from the user through parsing. The search term analysis unit 112 determines whether there are a plurality of search terms, and if a plurality of search terms are input, search each search term in the site list database 120 to determine whether there are site related words among the plurality of search terms. If the search term analysis unit 112 includes a site related word among the plurality of search terms, the search term excluding the related word of the site among the plurality of search terms (hereinafter, referred to as a “minor search term”) and a network address of the corresponding web site 300 are included in the first search unit. Provided at 114. In addition, the search term analyzing unit 112 provides the received search term to the second search unit 116.

The first search unit 114 accesses the web site 300 with reference to the network address received from the search term analysis unit 112. The sub-search word is entered into the search box included in the search page of the accessed web site 300 to request a search, and the search result is provided from the web site 300. Thereafter, the search result provided from the website 300 is transferred to the search result providing unit 118. The first search unit 114 and the web site 300 may exchange data written in a hypertext markup language (HTML) or an extensible markup language (XML).

For example, if the search word input from the user is 'KBS Chilju', the search term analysis unit 112 parses the input search term and divides the search term into 'KBS' and 'chiljuju', and the site list database (for each separated search term) 120). Since 'KBS' is registered as a site-related word, the search term analysis unit 112 reads the network address 'www.kbs.co.kr' for the site-related word 'KBS' from the site list database 120 and searches for the sub-query 'Chillongju'. Along with the first search unit 114. Then, the first search unit 114 accesses the web site 300 of the Korea Broadcasting Corporation 'www.kbs.co.kr' and requests a search result for 'Chillongju' and receives the search result therefor.

When the second search unit 116 receives the search word input by the user from the search word analysis unit 112, the second search unit 116 searches the search database 130 and searches the search list having the index word including the received search word in the search database 130. Extract. Thereafter, the second search unit 116 provides the extracted search list to the search result providing unit 118 as a search result for the search word input by the user.

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

An example of a method in which the search result providing unit 118 generates a web page including a search result will be described with reference to FIG. 3.

3 is a diagram illustrating an example of a web page provided as a search result in the search system according to the present invention, and illustrates a case in which the user inputs 'KBS Chilju' as a search word.

Referring to FIG. 3, the search result 420 received from the first search unit 114 is disposed at the bottom of the web page 400, and the search list 410 received from the second search unit 116 is provided. It is placed on top of the web page 400.

The search result (420) is the search result and contents provided by the website (300) when the word “chiljuju” is entered into the search box of the website of the Korea Broadcasting Corporation (www.kbs.co.kr). Is substantially the same. The search result providing unit 118 may insert the search result 420 received from the web site 300 into the web page 400 in an inline frame (IFrame) manner. IFrames are HTML elements that allow the insertion of other HTML documents into the main web document. The search result 420 inserted in the IFrame method has an advantage that it can be seen and used by the user as provided by the corresponding website 300. Of course, the search result providing unit 118 may also change the search result 420 according to its own criteria and provide the result. For example, a shortcut or more button may be added in the search result 420.

Meanwhile, although FIG. 3 illustrates that the search result 420 received from the first search unit 114 is disposed at the bottom of the web page 400, the location of the search result 420 may be changed as necessary. The search result 420 provided from the web site 300 may be placed on the top of the web page 400 to be provided to the user, and the web page 400 may be split left and right and the search result 420 may be left or right. ) Can also be placed.

On the other hand, the order of the site-related words and sub-search terms in the search word entered by the user does not matter. In other words, even if you enter 'KBS seven princesses' or 'seven princess KBS' can have the same search results.

In order to provide more accurate search results, a search method according to an embodiment of the present invention may be allowed for a predetermined subsearch word. For example, as if 'seven princess' is provided in 'KBS', the user may enter a search word on the assumption that the content corresponding to the sub-search word is provided by the web site 300 corresponding to the site-related word. Therefore, if a sub-search word input by the user is registered in advance and a word related to the content provided by the corresponding website 300 is performed, the search operation may be provided to the user by performing a search operation as in the embodiment of the present invention. have.

In general, since there is a high possibility that the web site 300 corresponding to the site-related words may provide content corresponding to the sub-search word, the site-related word and the sub-search word may have a close relationship. Therefore, if a user inputs a search term related to each other and includes a site related word, the search result according to the search system according to the embodiment of the present invention may satisfy the intention of the user. You will be more satisfied.

4 will be described in more detail with respect to the operation of the search system 100 according to an embodiment of the present invention.

4 is a flowchart illustrating the operation of a search system according to an embodiment of the present invention.

First, when the operation is started to receive a search word from the user terminal 200 (S510), the search term analyzing unit 112 analyzes the search word through parsing (S520).

The search term analyzing unit 112 transmits the search word input from the user to the second search unit 116 to allow the second search unit 116 to search the search database 130 for the search word (S530). Step S530 does not significantly affect the overall operation even when performed at any time after the search word is received from the user until the search result is provided to the user.

When the search term analyzing unit 112 determines whether the analyzed search words are plural (S540) and determines that a plurality of search terms have been input, the search term analysis unit 112 searches each search term in the site list database 120 to determine whether there are site related words among the plurality of search terms. (S550).

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

The search result providing unit 118 receives the search results from the first and second search units 114 and 116 and generates a web page including the search results in a predetermined manner and provides them to the user terminal 200 (S580). ). If 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 and provides the search result to the user terminal 200 only with the search result of the second search unit 116.
