Research On Intelligent Information Retrieval Technology Based On Concept Retrieval

With the development of Internet, Internet has been thoroughly applied in all trades and professions. Information in Internet grows miscellaneous and Internet users find that it is becoming more and more difficult to search and gain information available. The search engines, serving as the retrieval tool of internet information, are facing extreme challenge.This article beginning with information search and search engine serving as the retrieval tool of Internet information, it points out search engines are facing challenge and pivotal question. The paper deeply studies the intelligent information search technology which represents intending development of information search and analyzes some characteristics and technique of intelligence retrieval engine. It points out that the intelligent information retrieval system is characterized concept retrieval.Intelligent information retrieval system is characterized not by simple key word match, but concept retrieval as its core. The basic principle and properties of concept retrieval have been introduced in the paper. Then, the paper introduces the construct of concept semantic network and the principle of development of Concept Retrieval based on knowledge base. According to the design thought , a new system structure to search engine that enlarges the domain knowledge-base and users knowledge-base and enhances the function of user interface has been put forward in the paper. It also indicates that the veritable intellectualization of search engine must be supported by knowledge base.
