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, the search system 100 according to an embodiment of the present invention includes a search server 110, a site database 120, a site matching unit 130, and a search database 140 connected to each other. In addition, the communication network 10 is connected to the plurality of user terminals 200 and the plurality of web sites 300.

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 cover local area network (LAN), metropolitan area network (MAN), wide area network (WAN), internet, etc. It doesn't matter what type of communication you choose.

The site database 120 stores keywords and network addresses of representative sites corresponding to the keywords. Here, the keyword refers to a word designated to be provided to a user by receiving a search result for the web site 300, and the representative site is the most relevant to the keyword among the web sites 300 that provide a search function. The web address means a web site, and a domain address or an IP address (internet protocol address) of the web site 300 may be used. Correspondence of the keyword and the representative site network address may be made by the site matching unit 130 described below or directly by the operator of the search system 100 and stored in the site database 120.

The site matching unit 130 associates the keyword with the representative site network address of the keyword and stores the keyword in the site database 120. In more detail, the site matching unit 130 identifies web sites having relevance within a predetermined rank for each keyword, and among them, determines a web site providing a search function as a representative site for the corresponding keyword and selects the network address as a keyword. Match with. When there are a plurality of web sites 300 that provide a search function, the representative web site 300 may be determined to be the most relevant web site.

The site matching unit 130 may calculate the relevance of the keyword and the web site by the following method.

The first way is to determine the relevance ranking based on the number of clicks on each keyword for that keyword. In other words, when a user clicks a link in the quick view to view more detailed information on the search result screen for the keyword, the extracted URL information is extracted and the number of clicks of the web site including the URL for the keyword is increased. In this way, the total number of clicks per website for the keyword is examined and the order of relevance is determined according to the order of the number of clicks. For example, in a search result screen for the keyword 'Jumong', the more times a user clicks on a URL containing "www.imbc.com" and visits the website of the cultural broadcasting, the more the website of the cultural broadcasting is about the keyword 'Jumong'. It can be regarded as highly related.

In the second method, a relevance of a keyword and a web site may be calculated using a predetermined ranking algorithm. For example, the site matching unit 130 may use a ranking algorithm that calculates a relevance based on the frequency of keywords included in a web page of the corresponding web site. Of course, the site matching unit 130 may calculate a relevance between the web site and the keyword by using another ranking algorithm.

Meanwhile, according to the exemplary embodiment, the relevance of the keyword and the web site may be calculated by methods other than the above two methods.

Meanwhile, the specific keyword may correspond to a network address of a representative representative site predetermined by the operator of the search system 100.

The search database 140 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 listing may include a title, a URL, a description of the web page, an index word, and the like. 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 word processor 112, first and second searchers 114 and 116, and a search result provider 118, and displays a web page including a search box. The user terminal 200 receives a search word from the user, performs an appropriate search operation on the search word, and provides the search result to the user.

The search term processing unit 112 searches the site database 120 for search terms received from the user and determines whether there is a matching keyword. If there is a keyword that matches the search word received from the user, the search term receiving unit 112 provides the first search unit 114 with the network address and the search word of the representative site 300 corresponding to the keyword. In addition, the search term processor 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 word processor 112. The user inputs a search word in a search box included in a search page of the accessed web site 300, requests a search, and receives a search result 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 corresponding 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 'seven princess', the search word processor 112 inquires the input search word to the site database 120. If 'seven princess' is registered as a keyword, the query processing unit 112 extracts the representative site network address 'www.kbs.co.kr' for the 'seven princess' from the site database 120 and searches for the word 'seven princess' along with the search term 'seven princess'. 1 is transmitted to the 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 a search word input by the user from the search word processor 112, the second search unit 116 searches the search database 130 and extracts a search list having an index word including the received search word from the search database 140. do. 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 'chilju princess' 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. The web page 400 may be divided into left and right and the search result 420 may be left or right. You can also place

In order to provide a search result corresponding to a user's search intention, the search system 100 may receive the search result 420 received from the first search unit 114 and the search result on the web page 400. The arrangement position of 420 may be previously set by the user. If the user has previously set that the search result 420 received from the web site 300 is not provided, the search result providing unit 118 searches only the search list 410 received from the second search unit 116. Can be provided as a result.

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 an operation is started and a search word is received from the user terminal 200 (S510), the search word processor 112 transmits a search word input from the user to the second search unit 116 so that the second search unit 116 transmits the search word. The search database 130 is searched for the search word (S520). Step S520 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.

The search term processor 112 searches the site database 120 for the search term input from the user and determines whether there is a keyword match (S530). As a result of the determination, if there is a matching keyword, the representative site network address corresponding to the keyword is extracted and transmitted to the first search unit 114 together with the search word (S540). Then, the first search unit 114 accesses the web site 300 corresponding to the representative site network address, makes a search request for the search word (S550), and receives a search result from the corresponding web site 300 ( S550). If it is determined in step S530 that there are no keywords that match the search word, 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 (S570). ). 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.
