Social Network Mining And Analysis Based On Social Media

Social Media plays a very positive role in promoting the flow and intertaction of information in this web information filled time. Social Network framework is the mechanism and source of fast flow and spreading of information.Therefore it is important to mine and analyse the social network hid in social media using data mining technology.And mining the social network automatically helped to reveal the cause driving the development of social media. Nice visualization of the network can give a clear view for the user, and it provides features for the user to support the application in information retrieval, information recommendation, information dissenemination, e-commerce, advertising and so on.The main task is to mine the social network of people in social media, giving a brief analysis of the network and a microblog data-based social networking application.The paper carries out its research from data mining, network construction, network analysis and related application. The main tasks are as follows:Firstly, this paper selects Wikipedia and Sina microblog as two samples of social media. We first extract the information of person entities and give a unified notion model of person entities, then give a brief introduction of Wikipedia and Sina microblog and the information acquisition meathod, and finally give out a notion model of person entities suited for these two media and we also give out the related experiments and the result of them.Secondly, this paper proposes a group of person correlation computing methods and also proposes a network construction meathod. According to the feature of social media, we choose different methods or the combination of some methods to get person correlation, and then get the related network using the network constructing method. This paper uses the precision of these methods applied to Wikipedia and Sina microblog to show that the methods we proposed are correct.Finally, based on the work of correlation network, this paper do some work on community detection, and give an introduction of the social nerwork application based on microblog. A short introduction of social network analysis and GN algorithm is provided, some experiments of community detection using GN algorithm shows that the correlation network is meaningful to present the relation between people. Besides, two applications are developed, and they are social nerwork application based on microblog and a person recommendation application.
