Research on the Evaluation of Microblog Topic Influence Index Based on PCA Methods
As the emerging interactive social network platform for people to receive and share information, microblog makes the genera-tion of influential topics possible. As the early stage of network public opinion, the evaluation of the influence of online topic has great sig-nificance. Based on the concept combination and components definition of topic influence, this research proposes a new concept of microb-log topic influence index ( topic-I index) which contains three dimensions:participants, topics and network. Applying PCA and huge vol-ume of real data to assign each index weight, we eventually obtain 7 principal components and the calculation methodology of topic-I in-dex. Finally, the paper provides the application example of this index to provide network public opinion decision supports for topic man-agement administrators.
