Abstract: Sentiment community detection in social networks would be very valuable in many areas, such as public health, public opinion monitoring and so on. A framework of sentiment community detection was established on Sina Weibo. Firstly, the sentiment expression features and lexicon of Weibo were combined, and the classification model SL-SE-NB (naive Bayes algorithm based semi-lexicon and semi-emoji) was proposed to predict the sentiment polarity of texts. And then, the UTK (user-topic-keywords) model based on LDA (latent Dirichlet allocation) was proposed to extract user topics. Based on LPA(label propagation algorithm) and adding topic concepts, SMB-LPA (label propagation algorithm based seeds and min-edge betweenness) was proposed to discovery sentiment community. Finally, the experimental results proved the effectiveness and efficiency of the proposed algorithms.

Key words: social network; sentiment community detection; sentiment analysis; topic model; LDA(latent Dirichlet allocation)
