Collected Information Based On Regular Expression Engine Applied Research

As a main kind of method to retrieve information on Internet, search engine has been used widely in many fields. However, with the rapidly increasing of Internet information, the traditional search engine cannot meet people's demands on intelligent and personalized information service. So this paper puts forward intelligent professional information search engine, and puts the emphasis on the research of the crucial technology concerning with the intelligent information retrieval system.Intelligent professional information search engine make a progress to the technique of the search engine. It can be used as a traditional search engine. As it has the ability of analyzing and saving the information on webs intelligently, it can work more accurately and has a much wider search range. This system aims at cutting short the result of a search from a web to more useful information. It also experiences the individuation of the search engine and achieves our goal. Because of the succinctness of the output, it can be used in the mobiles, too.This paper analyzes the system structure of traditional search engine. After research most of search engine, we promote a new frame structure to realize this system. It improves all the modules of search engine, forms a new search engine structure and try to add self learning function to make it more intelligent.Paper also contains the researches of processing of the information on webs. With the help of REs and self learning system, it analyses and matches webs'structure, using the technology of webs'structure analyzing. With this module, system could picks up and saves key information on webs automatic.A new database structure is offered. The key part, strategy lib, is added for the self learning function. We experience it in all the cases, the case of much large number of information including.
