The present invention relates to a method and system for providing a search service using an information source. More specifically, in an information service or information retrieval service using a wired or wireless Internet, when a user inputs a query to be searched by the user terminal, it is determined to which information source (information provider) the inputted query word corresponds to a specific attribute of the information source. The present invention relates to a method and system for providing a search service using an information source for improving information depth, coverage, and accuracy by providing information as a search result.

As information technology advances to the information society, the Internet is becoming an important and essential medium in all fields such as society, culture, and economy. In order for a user to view a specific web page using a web browser such as Internet Explorer, a user generally needs to input an address of a URL (Uniform Resource Locator) of the web page. Therefore, if the user does not know the address of the URL of the web page, it is difficult to access the target document.

Therefore, even if you do not know the URL information of the Internet site, the software that finds the information you want among the vast amount of information flooding on the Internet has emerged, such software is collectively referred to as a search engine (Search Engine). The principle of the search engine is that a given search program called a search robot or spider program navigates through a number of sites opened on the Internet, stores the information of pre-collected websites into a database, and then the user If entered, only the web sites with contents that match the query entered in the database are presented.

In the early stages of Internet service (eg, first generation), such search engines search and classify each Internet site and web document in a database, and build a database based on the user's keyword search or menu search. As we refine our classification, we use a directory search approach that provides access to the final data.

To register your webpage on a search site that supports directory search, the administrator of the search site registers the URL of this webpage directly, or the administrator of the URL of this webpage can ask the administrator of the search site to There is a way to apply for registration. In this case, the administrator of the search site that received the registration application directly accesses and evaluates the web page, and then decides whether to register the search tool in the category.

Such a directory search method has the advantage of being easy to search while following a pre-categorized subject word if it knows only the kind of information needed, and is fast because it searches information already stored in a database on the search engine side. In addition, there is an advantage that the directory has a high reliability of the document, which is determined by the administrator of the search site to directly evaluate the web page that applied for registration to determine whether to register the web page with low or poor information Because.

However, as the number of websites increased rapidly, as in the first generation search engines, the method of manually checking a single web page and storing the verified web page as a database was not sufficient to keep up with the increasing trend of the website.

For this reason, a second generation search engine has been introduced that introduces the concept of a search robot mentioned above and provides a search service by automatically searching and indexing web pages. The second generation search engine uses a query input method and searches all web documents related to the user's query and provides them to the user's computer. It is inconvenient to find again in the search results screen. Therefore, in order to make up for such drawbacks, despite the huge burden on the system or human resources, the present invention provides a mixture of directory search services used by the first generation search engine.

However, a search result screen using a directory search expression or a query input expression is merely a simple list of a number of related websites or web documents based on accuracy or popularity. Therefore, the user has to click the website or web document displayed on the search result screen provided in the search site and search for the desired information, so that the user has to take the hassle and inconvenience of time and effort.

In addition, the web document collected by the search robot collects URLs linked to the seed URL manually input by the administrator of the search site. Therefore, the web document collected by the search robot depends on the amount of seed URL input by the administrator. The amount is determined. However, since the seed URL of the current search site is a method of relying on the manual work of the administrator, it does not sufficiently reflect the exponentially increasing website.

The existing simple search method based on the number of keyword matching is based on the number of times the query appears in the searched document. As the amount of searched documents increases, the number of search results provides numerous search results and the documents that are important to the user are selected. It was difficult to do it. In order to measure the importance of a specific document, a method of measuring the number of times a user clicks on a result, etc. is used.

The document dereference based method measures the importance of the document by giving a higher weight to the document with a lot of dereference, and gives a high weight to the keywords used as the title when referencing the link. How to calculate importance. The method of using the dereference information between documents has a limitation in that it does not directly reflect users' preference for information by measuring the value of information by the mutual link between documents. In particular, the dereference information between documents is difficult to reflect the tendency of the dynamic user's dynamic information due to the static information characteristics.

On the other hand, the method of measuring the number of clicks on the search results is meaningful in terms of measuring the user's response to the information, but in the measurement, only the search results are targeted. In addition, there is a limitation that it is impossible to measure the information preference about the case of directly visiting the corresponding URL without using the search system.

In addition, search robots collect URLs linked to seed URLs, which are almost exclusively limited to existing websites or webpages, which are associated with communities such as clubs, fan clubs, games, chat, and search. It has a disadvantage that it is impossible for web robots to efficiently collect bulletin board related URLs, media file related URLs, and newly created websites or web pages.

Since all the search methods described so far are to find a query matching relationship in a web page, there is a problem that the corresponding page is not searched if the query to be searched in the page is not exactly displayed. For example, if the query is "011", the announcement "SKT basic fee 1,000 won reduction" in the SKT homepage may not be searched. This is because the page of the post "SKT basic rate cut" may not contain the word "011". However, the information "SKT basic fee 1,000 won reduction" can be very useful for users searching for "011". Therefore, a search result generated by simply querying a query in a web page cannot be an accurate search result. exist.

 In order to solve the above-mentioned problems, the present invention, in the information service or information retrieval service using the wired and wireless Internet, when a user inputs a query to be searched by the user terminal to determine which information source (information provider) the input query word corresponds to An object of the present invention is to provide a method and system for providing a search service using an information source that improves depth, coverage, accuracy, etc. by providing specific attribute information of the information source as a search result.
