Abstract：This paper focuses on clustering different feature expressions in product reviews into proper groups. In product reviews, the same features may have different expressions, e.g. “appearance” and “design” of a mobile phone actuallyindicate the same feature. Considering the fact that different expressions are always used with same sentimental words in a sentence, this paper first extracts product feature expressions and sentimental words in pairs to build a bipartite graph, and then adopts the Weight Normalized SimRank to compute similarity between different feature expressions in the bipartite graph, and finally optimizes the Bayesian classifier in Semi-Supervised Learning via the similarity. Experimental results show that the proposed method is valid. Key wordsproduct features; group; SimRank; semi-supervised learning
