Design And Implementation Of Power Grid Enterprise Network Public Opinion Monitoring System

Although the problem of public opinion information monitoring network has been business concern and attention, but because the source of the information network public opinion no boundaries, monitoring object is too broad and difficult real-time monitoring; rapid development of the Internet, technology has also brought it means changing the management of public opinion big challenge. Because of social citizenship and mutual understanding and less power grid enterprises communicate, together with its operating characteristics and mode of operation of the particularity to enable power companies to more easily become sensitive to public opinion and hotspots.Based the development status and characteristics analysis of power grid enterprise network public opinion in public opinion monitoring management system at home and abroad, the research and application of network technology, the main crawler reptile realize data acquisition system, research and application of web page purification, Chinese word segmentation information pretreatment technology to realize the analysis engine. Based on the needs analysis related to the overall function of the system requirements, performance requirements and the needs of database research. In this paper, the overall design to the overall framework, the use case diagram, state diagram, activity diagram, ER diagram, database tables, system architecture, workflow, network topology, etc. to carry out system design. In the module design to public opinion portals, public opinion monitoring, classification of public opinion, thematic trends, public opinion work, statistical analysis in this article, real-time updates and system management, launched a modular design.This paper systematically have achieved through the MVC architecture of J2EE application server and relational database. In this paper, the reptile collection system strategy, task configuration, real-time updates, analysis hot topic recognition engine, a sensitive topic identification, negative judgments, public opinion, warning, focus reproduced, public opinion, public opinion portal application, classification of public opinion, the topic of public opinion, public opinion work, Statistics analysis, public opinion search, system management, etc., to achieve a more systematic exposition of the module. Finally, the study carried out system testing test environment, basic functional testing and performance testing on the study of routine operation and maintenance of the systems and contingency plans. In this paper, the system has been used to achieve grid operation and management of public opinion monitoring company Luliang area, and the system is responsive, accurate judgments, good interface and so on.
