Abstract


With the continuous progress of the industry of information technology, more and more enterprises and institutions via the Internet Ads. On the Internet there are a lot of professional information and how to overcome the problem of information overload and resources isotropic encountered in the network information search process, efficient and quick way to get professional information in the field of today's network information search field of study has become a new direction . Search for specific areas with good professional directional search object is clear, the relative concentration of resources, to some extent, to overcome the divergence of network resources, complexity, diversity website and web pages, you can easily keep up with the growth and updates the speed of the analysis of the document, the establishment of the automatic processing and field-oriented knowledge base is also relatively easy to achieve. In this paper, the research project \Development and research status of the network information search, pointed out the problems of the existing network information search system, and the future direction of development of network information search; made a lot of network information search technology research foundation , the paper proposes a feature extraction based on the information block and analytical methods, according to the size of the significance of the transmission of information, the page is divided into different blocks for different blocks based on the content and structure of information mining. Professional information capture technology research, the vector space-based network of professional information acquisition model, a field-oriented website content-based index database to achieve professional field of information extraction Robot crawling. Algorithms and professional search strategy. Meanwhile, user knowledge model was constructed based on the degree of professional interest, to provide users with personalized service, to improve the system's intelligence. Including professional interest access model and optimization, feedback processing and other aspects of research. Finally, an application example in the field of textile and chemical fiber the --- SOKEY system, introduced SOKEY overall system architecture and workflow, and Active Server Page 3.0, VBScript and other embedded programming language used on the Windows 2000 Server platform and object-oriented database technology to complete the information on the website dynamic refresh the document information automatically query segments of information browsing, user information transceiver module, is done with a VC network information automatically capture module.
