INSTANT SEARCH SYSTEM AND METHOD USING SEMANTIC INFORMATION}

The present invention relates to a search system and a search method, and more particularly, by using a semantic information, if a command and a keyword are input, the semantic information can be used to quickly and accurately obtain information desired by a searcher by immediately displaying a search result without switching the screen. It relates to a direct answer search system and a search method.

In general, conventional portal (search) sites such as Naver, Dreamwiz, Daum, Yahoo, etc., provide a database for classifying and storing web site information according to a predetermined criterion, and mechanically convert new web site information while continuously traversing the web. It consists of a search robot for collecting data and a search engine that makes the collected data into a database so that users who use portal (search) sites can search. When a portal site user enters a keyword, the search engine searches the database for keywords. Provides a list of similar sites at.

Internet search engines are classified into a directory search engine, a keyword search engine, and a meta search engine according to a search method. A directory search engine is a search engine that classifies materials by subject or category, and builds a database by adding explanations and evaluations. The keyword search engine collects web documents by the web document collection program and stores the collected documents in the search engine's database through the indexing process and searches the user's query words by keyword matching method.

The Semantic Web, on the other hand, gives well-defined meanings to information on the Web, allowing computers as well as humans to easily interpret the meaning of documents, thus automating tasks such as searching, interpreting, and integrating information using computers. It is proposed for the purpose of doing so. Semantic Web documents have meanings that can be easily interpreted by computers, unlike existing web documents focused on natural language, so that automated agents or sophisticated search engines can use high meanings to achieve high levels of automation and intelligence. .

In the Semantic Web, resources are expressed in triple form of resources, attributes, and attribute values, and RDF (Resource Description Framework) is defined as a framework for resource representation. The semantic web uses SPARQL as a query language for retrieving resource information expressed in RDF, and is used as a protocol for transmitting queries in a client-server environment.

In the conventional keyword search, if a search is performed after inputting a keyword, the keyword input screen is converted to a search result output screen and the search result is displayed, thereby causing a time delay and cumbersome problems due to screen switching. In addition, in the conventional keyword search, since only a list of web pages that match the input keyword is provided as a search result, there is a problem of reloading the corresponding web page to obtain desired information.

The present invention has been proposed to solve the above problems, an object of the present invention is to use the semantic information to input a search word in the structure consisting of "command and keywords" to be able to see the desired information directly on the search word input screen It is to provide a direct answer search system and search method using semantic information.

In order to achieve the above object, the system of the present invention, a semantic database; In addition to providing a search term input screen consisting of commands and keywords, when a search term is entered through the search term input screen, the search term is transmitted to the semantic search robot. When receiving a search result from the semantic search robot, the search result information is displayed on the search term input screen without switching the screen. Search server for outputting; And a semantic search robot that divides a search term into a command and a keyword when the search word is transmitted from the search server, interprets the command, and then semanticly searches the semantic database with the recognized command and keyword to deliver a search result to the search server. It is characterized by including.

The search server displays only a part of the search result information when there is a lot of search result information and then uses the scroll bar to view the hidden information or press the arrow (↓) to view the hidden information.

In order to achieve the above object, the method of the present invention comprises the steps of: requesting a command input by providing a initial screen for inputting a search word when a searcher connects; When the searcher inputs a search word composed of a command and a keyword, the search server transferring the input command and keyword to the semantic search robot; Comparing the command with a predefined command table by the semantic search robot, recognizing the command, and searching the semantic database to extract only the search result information corresponding to the command from the search result and transmitting the same to the search server; And if the search server has a search result, output the search result directly to the search word input screen without switching the screen, and if there is no search result, outputting no search result.

The search word is composed of a command and a keyword separated by a space or a special character, the keyword is composed of one or more words, and a direct search method using semantic information includes a help button or a reset button. The search server outputs a help, and if the reset button is input may further comprise the step of clearing the input search word or search results output.

The direct answer search system and method of the present invention is a structure consisting of a "command word and a keyword", when a search word is input using semantic technology, the searcher directly outputs the desired information on the search word input screen without screen switching, and thus the information desired by the searcher. Can be provided quickly and accurately.

The technical problems achieved by the present invention and the practice of the present invention will be more clearly understood by the preferred embodiments of the present invention described below. The following examples are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

As shown in FIG. 1, the search system 110 according to the present invention provides a semantic database 113 and a search term input screen according to the present invention, and when a search term is input through a search term input screen, a search term is semantic search robot. And a search server 111 for receiving the search results from the semantic search robot 112 and outputting the search result information on the search term input screen. After the command is divided into and keywords, the semantic search robot 112 is searched to search the semantic database 113 as a keyword according to the meaning of the recognized command and deliver the search results to the search server 111.

Referring to FIG. 1, when searchers 120-1 to 120 -N access the search server 111 through the Internet 102, the search server 111 is connected to the present invention as shown in FIG. 4. Provides an initial screen for searching. When the searchers 120-1 to 120-N enter the 'command' and the 'keyword' separated by 'spacebar' as shown in FIG. 3 on the initial screen of FIG. 4 and press the enter key, the search server Reference numeral 111 transfers the input command and keyword to the semantic search robot 112. The semantic search robot 112 recognizes a command by comparing the command with a predefined command table, and then semantic search the semantic database 113 to extract only the search result information corresponding to the command from the search results. To pass. The search server 111 directly displays the search result information received from the semantic search robot 112 on the command input screen without screen switching. At this time, if there is a large amount of search result information, only a part of the information is displayed and the scroll bar is used to view the hidden information, or the arrow ↓ to see the hidden information.

Subsequently, the search procedure according to the present invention will be described in detail with an example of an actual screen.
