Social network mining based on improved vector space model

We employ a method to mine social networks of person entities from Wikipedia in this paper. A person entity is represented as a vector by anchor text set and content text set of his page in Wikipedia using Improved Vector Space Model (IVSM). We use cosine similarity of the vectors to present the similarity of person entities, and at last we get the similarity array of all the person entities. Finally, we extract the social network from the array which shows the relations of person entities. On Wikipedia data, we conduct some experiments on social network analysis, and the experimental results show our social network mining approaches are effective.
