Research On Enterprise Competitive Intelligence System Based On Web Information Extraction

Modern society is characterized by the network of information. Competition for information has been playing a very important role in the competition between enterprises. Through intelligent information processing, collection, analysis of valuable intelligence information of enterprise, the enterprise can make more wise decision, response timely to the market and the environment and gain advantages in competition. Therefore, construction of enterprise's informatization, establishing the competitive intelligence system has become a strategic choice for most enterprises. In the internet era which enterprises are faced with the explosive growth of information, how to effectively take advantage of this great information resource is a new issue in the research of competitive intelligence system.This paper first explains competitive intelligence and the knowledge related to this kind of competitive system and promotes the new problems that exist in competitive intelligence in the information era. At the same time, it summarizes some characteristics associated with enterprise competitive intelligence system in the network environment and its future trends. Secondly be against the characteristics, that is, massive web data of network information times as well as the direction of its future development, this paper studies the competitive intelligence system structure. Meanwhile it thinks of improving the competitive intelligence of traditional information processing flow, an increase of the core information extraction subsystem, and offering the enterprise competitive intelligence system's technology framework that is based on J2EE . After the research about the extraction of information technology, this paper proposes the method to solve the information acquisition problem effectively in enterprise competitive intelligence system under the internet circumstances using web information extraction technology. Finally it establishes a model of extraction system and studies the extraction system in enterprise competitive intelligence information system. Then, it introduces another information extraction system which is based on XML to help the enterprise lay a good foundation for establish an efficient and intelligence competitive intelligence system.
