Abstract  

[Objective] This paper aims to improve the performance of automatic abstracting with the help of “Doc2vec” model and improved K-means clustering algorithm. [Methods] First, we introduced the Doc2Vec model, which could examine the document contextual information, to extract the semantics, grammar and word sequences of Chinese document sentences. Then, we transformed these sentences to vectors of fixed dimensions. Third, we identified clustering centers for the improved K-means algorithm, and then processed the sentence vectors. Finally, the sentences with larger information entropy in one cluster, as well as higher similarity with other sentences in the cluster, were extracted. [Results] Compared with the PLSA method, the precision, recall, and F value of the proposed model increased by 9.57%, 7.62% and 10.30% respectively. [Limitations] We could not use the sentences extracted from the documents to generate high quality abstracts. [Conclusions] The proposed method could improve the performance of automatic abstracting of Chinese documents.
