The Research And Application Of Internet Public Opinion Information

Internet public opinion is the integration of various emotions,attitudes and opinions of all types of social events which are closely concerned by the oariety of citizens in a certain space.These explosive internet public information,especinlly those sludden event will arouse the interest of various sical groups.In this case,and is hard to classify and do some statistics.Then,the use of computer technology to analyze information on the Internet public opinion is helpful to establish an effective monitoring and early warning mechanisms.Therefore,strengthening the network public opinion analysis monitoring technology research has become an urgent and important issue.Based on this background,this paper analyzes the network public opinion monitoring implementation techniques and specific applications are studied.This prior in-depth investigation of public opinion related to the field of network theory and technology,focusing on network public opinion monitoring the application of technology,involving key technologies carried out research.To analyze a web crawler,content,noise removal,re-ranked pages,text formalization,feature selection techniques.Subsequently,the combined universities truth,through needs analysis,functional module design,database construction,system architecture,based on real university network environment,a set of campus forums public opinion analysis monitoring system design,and discusses in detail the major systems involved function modules(eg : information collection,data preprocessing,intelligence analysis,public opinion services and other modules)are ways and means of how to achieve.In addition,the system design process,the current study also introduced a popular target : Text orientation analysis technology,and based on Bayesian algorithms discussed in this opinion analysis system which implemented the idea.Finally,the article also through four testing laboratories to verify the availability of the system,as well as related functions(topic detection,topic tracking,text segmentation,public opinion warning)is effecti ve.The research work on other Internet content analysis system development and design,and management of university network monitoring public opinion has a certain reference value.
