Researchand Implement On Technology Of Public Opinion Guidance Of Online Community

With the wide use of computers, Internet has developed so fast and become apart of people’s lives. Nowadays people tend to get information more often fromInternet other than radio, television and newspapers. People can express theiremotions, attitudes, opinions and requirements through network communities. Thus,all these public opinions form the public opinion of network communities, and alsoInternet has become the main position of social opinion activities. Currently, publicopinion is mainly guided by releasing information manually, which requires a lot ofmanpower and material resources and cannot satisfy the practical needs. Therefore,Internet public opinion guidance has become a hotpot in academia.This paper starts from a technical perspective, proposes a technical solution forpublic opinion guidance and designs a public opinion guidance system. This paperdiscusses key technologies of public opinion guidance in detail: multi-sourceinformation collection, word paraphrasing and automatically releasing informationon network communities.First, in the multi-source information collection part the system collects theinformation from sites of different types, whose sources consist of four types:mainstream media website, blog, BBS and microblog. To ensure the stableness of theunderlying crawler architecture, we use different configuration files to collectinformation in the first three parts. As for the microblog source, we use open API tocollect information from microblogs to ensure the stability of the program.Second, synonym replacement is used in our paper. In this method, firstChinese sentences collected from the Internet are first segmented. Then thesegmented words are replaced by synonym thesaurus to get sentences of the samemeaning, which form new text corpus.Third, an auto-releasing information system is implemented based on Windowsplatform in this paper, which aims at both BBS and microblog. The system usesneural network to implement the verification code technology, WebBrower controllerand open API to automatically release information in BBS and microblogindividually.Finally, from the test results and analysis of the system, we conclude that it can solve the problem of public opinion guidance of network communities to someextent, which also has feasibility and application values.
