Research And Design About The Dynamic Analysis System For The Development Of Science And Technology

With the rapid development of Internet, network media as a new form of information dissemination, has penetrated into people’s daily life. More and more data of Internet technology comes from the major domestic and international science and technology media, social networking, Internet forums and so on. In view of our country’s scientific research institutions to use traditional methods of obtaining information to collect and manage the science and technology information, The existence of information acquisition is not comprehensive, poor flexibility, database security is limited and other shortcomings. How to quickly and intuitively retrieval technology information, saving a lot of time for users of statistics and analysis has become the urgent problem to solve.This thesis introduces the trend of development of science and technology development, The analysis of the existing science and technology information release system problems and weak links, in-depth discussion of key technologies and research content in the process of system development, those provide a reference for the efficient and comprehensive access to information and analysis of intelligent dynamic information.On this basis, we design and develop the dynamic analysis system for the development of science and technology. the system based on the basic database model, Using the technology of web crawler, information retrieval and extraction technology and network public opinion content analysis technology on the development of science and technology related resources for screening, integration, optimization, The system effectively integrates the latest science and technology information on the Internet, uses Data Shire middleware layered design idea to manage information. provides unified data view and analysis support environment, forms a market oriented dynamic report, integrates of a variety of data sources to realize a variety of access to information sources, builds the data warehouse infrastructure and automatic data extraction, convert, loading mechanism, realizes the generation and presentation of reports by using multi-dimensional analysis and data query tool.The system has carried on the system construction and testing in user’s company, The system function mainly includes the latest developments in science and technology publishing, technology services public opinion analysis, information query and retrieval, user rights assignment and management, realizes the public opinion information acquisition and dynamic analysis of intelligent manufacturing, health care, green energy, information network. as proved by the practical application, the system can meet the needs of users.
