Research And Development Of The Network Public Opinion Monitoring And Tracking System

Network public opinion formed rapidly and had a huge impact to the society. With therapid development of the Internet on a global scale, network media has been acknowledged asthe following newspapers, radio, television after the "fourth media", the network become oneof the main carrier of reflecting the social public opinion. Has increasingly become theimportant place of production and propagation public opinion, network public opinion plays amore and more important role in social life. Its directness, highlighting, deviation causes thenetwork public opinion double-edged sword role increasingly obvious. In order to strengthenthe network management and monitoring, how to better carry out the network public opinionmonitoring, tracking and analysis of information, has become the government, enterprises andinstitutions such as schools are faced with the primary reality problem. Network publicopinion monitoring and tracking system can realize automatic aiming at massive publicopinion in network real-time monitoring and analysis, effectively solve in the traditionalartificial way for public opinion monitoring, tracking and analysis of the problem.Traditional network public opinion focus tracking algorithm based on text clustering,when dealing with massive amounts of web page, text clustering speed is too low, pooraggregate the results. This paper proposes a network public opinion focus tracking schemebased on keywords extraction, and according to the weibo, news, BBS and blogs differentcharacteristics respectively hot spot analysis model is designed. Through the development ofthe woodpecker public opinion monitoring and tracking system experiments show that thescheme is effective, hot spot analysis model to identify hot spots high accuracy.Network public opinion monitoring and the traditional search engine, the biggestdifference lies in its timeliness is strong, the lag of information has no value. Timelinessincludes two aspects, collection and analysis of the timeliness and information efficiency. Isproposed in this paper, first of all, in vast amounts of website according to the influence of therankings, limited the authority of the mainstream sites selected as the primary source ofinformation collection, to make full use of limited resources, eventually improve monitoring efficiency.Finally, according to the situation of the development of the network, this paper presentsa specific application system the woodpecker public opinion monitoring and tracking system.Introduced in recent years in view of the network public opinion monitoring systemconstruction process of the problems and solve the specific problems, a comprehensiveanalysis of the design of the construction of the objectives and principles, and furtherexpounds the detailed function and finally realizes the functions, for timely and accuratewarning network emergencies and comprehensive analysis to make some contribution.
