The idea of social network analysis (SNA) can be traced back the study of Psychology and Anthropology in the 1930's. In the 1990's, social network analysis has entered a rapid development period. On the one hand, social network analysis theory has been further development, as Ronald ? Burt's "structural hole theory", Lin Nan et al, who study social capital, have a lot of research results; on the other hand, social network analysis techniques are more mature. From the disciplines, the social network analysis has crossed the boundaries of traditional disciplines. Its applications have been limited to sociology and anthropology, but rather extended to almost all areas of humanities, social sciences, science and technology. In the joint efforts of sociology, psychology, economics, information science, system science, and computer science, social network analysis has become an interdisciplinary research method.It is only based on the blog rating to show the influence of blog at present. And blog rating is obtained through numbers of visits. To some extent, it is not accurate to assess the influence of the blog.Above all, this paper proposes the concept of Blog Reliability, and the influence of blog is shown by it. Blogger's friends with links form a social network. We adopt the parameters of social networks to assess Blog Reliability, such as centrality , core-periphery, clique etc. Finally, we will verify the reliability of this assessment by a mount of data. |
