The Research And Implementation Of Public Security Organs Public Opinion’s Monitoirng System Based On Microblog

Microblogging public opinion has become the most influential in the network publicopinion transmission way, gradually become an important way to gather public opinion.Assuming the responsibility of safeguarding national network security of the ministry ofpublic security, the microblogging network monitoring of public opinion is imperative. Basedon this background, puts forward the concept of public security public opinion monitoringsystem based on Microblogging. Microblogging network public opinion in the research, onthe basis of core technology, combined with the public security organ of the microbloggingnetwork public opinion monitoring system business requirements, analysis of the geared tothe needs of the public security department of the main functions of the microblogging publicopinion monitoring system requirements (micro dig, Microblogging retrieval functions,microblogging public opinion analysis and microblogging public opinion display functions),system design goal and user characteristics. Then the system architecture including the systemcomposition, the technical architecture and system structure design, to realize system eachfunction module. And has carried on the function and performance test, this system guaranteeon the design and implementation, this system can meet the public security department to thedesign of the microblogging public opinion monitoring requirements.On the technical implementation, combined with the characteristics of Microblogging andof the business needs of the public security department, open source web crawler is putforward to Nutch applied to public security public opinion monitoring system based onMicroblogging, and to the secondary development of Nutch, increase the function of thevirtual log in to make it realize the microblogging platform information crawl. And bychanging the Nutch source to improve its network crawl waiting time rigid shortcomings,improve the efficiency of system crawl. Part in Chinese word segmentation system using cas ICTCLAS4J Chinese word segmentation technology research and development, effectivelyguarantee the information system for the microblogging participle function reliability. Andwill ICTCLAS4J integration into the Nutch, integration method is presented. High to themicroblog information collection and analysis of the system reliability and accuracy.
