Abstract

With the deepening of the construction of the development of computer network technology and information technology, units and departments within the network continuously improve the level of application, network development, the focus of the construction has been transferred by the network construction early Internet application services to the units internal Intranet network applications expand on. Each unit based on general operations of the department, relying on the Intranet network applications in various network environments in these applications, the Web become a mainstream application development platform, with dynamic scripting technology in the Web environment, database technology started to become a mainstream technology for Web application development, Web environment, information publishing capabilities greatly enhanced, interactive website contains a variety of information have sprung up. Accompanied by a shift in the focus of this construction and the application of new technologies, the level of network applications and information dissemination capacity of the units to a new level, followed by the explosive growth of the network information in an intranet environment, and how this information effective supervision and management units network management departments are facing new problems. With public information on the Internet and Intranet applications are closely related with the internal business units, and other aspects of life, more and more important as the network this nascent media's role in everyday life, these network information the importance and influence also becoming increasingly urgent need to address the problem of network managers, and therefore their effective supervision, and mass characteristics and the diversity of network information increased to solve this problem technical difficulty. This situation, the Building Intranet information monitoring system based on the information collected and full-text search technology, through the use of computer technology to achieve the initial screening of the Intranet, Web information collection and information for the network managers regulatory Intranet network information provides a viable solution. The data acquisition module can be completed in a short period of time by using the search engine technology crawling robot (Web Crawler, Web Spider), Intranet Web data collection and collation of information within the network, and then by the full text of the database retrieve large amounts of data collected preliminary retrieval and filtering. In the system development process, combined with the characteristics of the information within the Intranet network of the crawling robot technology improvement, adopted \and efficiency. The system provides a user interface based on B / S structure, to provide users with a search engine provides a practical, convenient web search service, on the one hand for Intranet users, on the other hand, by expanding the range of use of the system to improve system sensitive information, the ability to identify, record and analyze the history of user generated keywords combination of the SQLServer database full-text search engine-related parameter settings, to further improve the coverage and the extent of coverage of the system of sensitive information. The paper first a brief analysis of the situation and the difficulties faced by the Intranet network information management, and summarized the characteristics of the network information in an intranet environment, and on this basis, the network information by using computer software technology effective supervision of technical ideas for some of the technical difficulties in the system builds the solution, and system software structure, specific methods to achieve the brief summary of the last to achieve the goals of the current system has problems and needs to be improved were summarized.
