Qianxinan Public Opinion, Information Management Systems Analysis And Design

With the increasing development of information technology and penetration, "fourth media"-Internet media menacing, "public opinion, the crisis" at the growing network of information and effective monitoring of public opinion become a problem. Government guidance on how a reasonable and rational network of public opinion to resolve the incident, a rapid and effective information management system of public opinion has become a problem to be addressed, but also a problem worthy of study and discussion.The project comes from the work units of information technology projects-Qianxinan public opinion management system to the network for the study of public opinion, in-depth understanding of research status and knowledge of relevant theories, based on public opinion from the information discussed theoretically collecting, analyzing, reporting, and treatment process, build the information model of public opinion, public opinion, the information management system for the overall architecture and detailed analysis of the logical model. In this paper, B/S and C/S hybrid architecture, based on the Internet network, the use of object-oriented programming techniques and SQL Server2005 database technology, software design and development from the perspective of a systematic needs analysis and public opinion, the management of business process analysis, The overall system design goals and basic principles. Paper a detailed analysis of the system functional requirements, database structure, content management, public opinion approval, collected from public opinion, public opinion, the automatic classification, public opinion, early warning, public opinion, reporting, system management, system settings, and discussed the system requirements analysis and design, and were systematically tested. In the key algorithm, the use of web technology to achieve the text automatically collect information about the automatic acquisition and storage of public opinion, the use of Bayesian classification algorithm of the automatic classification of public opinion and the judgments of text, this is a manifestation of this innovation.This public opinion information about the test and theoretical analysis, management of public opinion, public opinion management unit provides a theoretical guidance and practical reference value.
