Abstract: [Purpose/Significance] In the era of rapid development of social networks, automatic summarization technology is increasingly required to cope with the overload of product review information. Aiming at the problems of incomplete information and poor accuracy in the extraction of comment abstracts by existing graph model methods, this paper proposes a multi text summarization method based on topic clustering and semantic graph model. [Method/Process] Firstly, the Fuzzy C-means(FCM) clustering algorithm was used to achieve topic division of review texts. Secondly, the Word2vec model was used to obtain the vectorized representation of the classified comment sentences, and the graph model was constructed according to the semantic similarity between the sentences. Finally, the weighted graph sorting algorithm was used to automatically extract sentences with high importance to form text summaries. [Result/Conclusion] The results show that this method can effectively identify the core content of product reviews. Compared with traditional methods, the method that fused topic clustering and semantic graph model achieves higher scores in information coverage and information diversity indicators, improving the quality and efficiency of abstract extraction.
