Abstract  As propelled by the rapid growth of text data, it is urgent to utilize automated tools to monitor the user relationship, topic trend and the implying values of the platforms. A new modeling framework based on LDA is proposed to evaluate the social networks automatically. The authors first map the text into topic space, eliminating the uncorrelated information based on topic distribution and user feature, then create an evaluation method from social network analysis perspective, mining the structure of the social network from three aspects including user centrality, topic popularity and community activity. Experiments show that promising results are achieved by the new model.
Key wordsSocial network      LDA      Topic model      Two-stage evaluation
