Abstract：Semantic integrity of the summary with intuitive subject-predicate-object structure is strong in the short text summarization task. However, part-of-speech combinations impose constraints on the structure. Aiming at this problem, an automatic short text summarization method based on part-of-speech soft template attention mechanism is proposed. Firstly, text is tagged with part-of-speech tags, and the tagged part-of-speech sequence is regarded as part-of-speech soft template of the text to guide the method to construct the structural specifications of a summary. Part-of-speech soft template is characterized at the encoder. Then, the part-of-speech soft template attention mechanism is introduced to enhance the attention of core part-of-speech information in text, such as nouns and verbs. Finally, the part-of-speech soft template attention and traditional attention are combined to generate a summary at the decoder. Experimental results verify the effectiveness of the proposed method on short text summarization datasets.
