Chinese Microblog Oriented Social Network Analysis And Application

With the development of computer network, Internet-based network virtual society hasemerged. As a new Internet information exchange platform, microblog is favorable to Internetusers. Its immediate, simpleness and convenience make information dissemination moreconvenient. Microblog has the character of social network, it associates microbloggers byfollow function. The analysis of microblog social network has been the focus of research. Ourresearch about the microblog social network include several aspects as follows:1．We analysis methods of modeling microblog network. The microblog network can beconsidered as a multi-dimensional network, each dimension corresponds to a subject network.Base on the communication mechanism of the microbloggers and microblog textclassification, this paper present a modeling method of microblogger interaction networkwhich is based on subject. The building subject network can be further divided intocommunities.2．To the short of microblog text, and motivated by the idea of semantic expansion, wepropose a microblog text classification algorithm which is based on domain feature word baseand the computation of word relevancy. Domain feature word base is a collection ofstandardized terminology of concepts in a field, its establishment is based on the CHI andconsidering the positive and negative effect of feature words. In the computation of wordrelevancy, HowNet is used to do semantic extension. And it fully considered relationshipsbetween the primitives.3．We analysis methods of mining the community core members. Firstly we introducedthe evaluation model based on centrality concepts of the social network analysis. Then afteranalysing the similarities and differences between microblogger interaction network and theweb link network, we modified the PageRank algorithm and proposed a WeiboRankalgorithm which used for mining the core members in microblog community.4．Base on the microblog data crawling technology and the result of microblog socialnetwork analysis, we preliminarily implement a microblog subsystem for Internet hotspot information monitoring system.
