Design And Implementation Of Network Public Opinion Analysis System

Public opinion is in a certain social space,with the occurrence of an event,development,and changes in public attitude towards the incident.Public opinion is the opini,on of the enlarged body,which the sum of people's views on social phenomenaideas,attitudes and opinions,but also the part of people's attitudes to social and political that in power to influence and guide decision making.Popularity of the network makes the mechanism of public opinion changing a lot.Public opinion is disseminating and changing in the network may eventually form a network of public opinion and may even affect the political system management,network public opinion has become one of the most important public opinion,which is the social network of public opinion reflected.With the development of the Internet,As its special role in the emerging network,public opinion is becoming the birthplace of public opinion and the amplifier.The Internet is a treasure,especially in the era of big data,with the aid of IT technology,realization of virtual network public opinion in a timely and comprehensive monitoring has been imminent.In this paper,we will mainly introduces the structure of Design and Implementation of Network Public Opinion Analysis System on Web Crawler and how the Web Crawler used in the application of Network Public Opinion Analysis System on Web Crawler?It is based on this background which paper will theory research and empirical study unifies,first studying network structure and characteristics and combining the actual situation of domestic Internet application.According to network public opinion information collection source of information is mainly coming from big BBS,online community,public blog and so on which users can focus reflects for a specific issue.Finally,although the topic of technology and hotspots found that technology is more mature,but encountered a lot of problems in the practical process of technology has seriously hampered the effectiveness of technology in public opinion monitoring system to establish a hot topic discovery model also has a high research significance and research value.Finally,by running the examples and test the feasibility and effectiveness of the model is validated.
