Based On Personalized, Professional Network Of Oil And Information Retrieval Technology

The information searches are the process that organized and saved according to the certain way, and search the information that the users need. How to get the useful information betimes and true is a problem that the modern network information searches technology need to solve along with the network information resource increase and real time update quickly. The experts have done many research and brought forward some methods, attempted to combine with the artificial intelligence technology, the date excavation technology, the homepage information and the user behavior to apply into the information searches, make the network information searches technology to develop to the intellectualized and individuation.This paper based on the research to the petroleum specialized network intelligent information searches system under the petroleum specialized background, and realize the frame. First of all, this paper analyze the existing network information searches technology, deeply research the individuation network information searches system and the pivotal technology; and then bring forward the user info requirement model based on the individuation, this model established via the method that extract the characteristic, in order to present the substantial characteristic of the user info requirement, advance the disposal efficiency and identify ability of the computer; finally, present a kind of mechanism prepared to filtrate the Web information source and the method to filtrate the Web homepage, exploit a antitype system according to this. The system provides a better project for the petroleum specialized user when searching the effective information in the Web network.In this paper, the user info requirement model parses via the Chinese demonstration Web homepage that the user refers, and then dispart words to text content of the Web homepage, extract the characteristic based on this, and adopt the vector space model to denote; the realization of the Web information collection is through a kind of Web homepage focusing gathering mechanism based on cell search,...
