Abstract

The invention relates to a text abstract model generation algorithm for fusing information selection and semantic association. Firstly, based on the Decoder model, the attention mechanism is combinedto obtain enough information of input sequence. Secondly, a copy mechanism and a coverage mechanism are used to solve the problem of non-login words and clause repetition in summary generation. Then aselective network is designed to encode the original text twice to filter the redundant information. Finally, by comparing the semantic relevance of the original text and the abstract, the semantic relevance of the abstract can be corrected, and the semantic relevance of the abstract and the original text can be enhanced.

Description

technical field [0001] The invention relates to the field of information selection and semantic association, in particular to a text summarization model generation algorithm that integrates information selection and semantic association. Background technique [0002] The Seq2Seq model based on the encoder-decoder framework was proposed and popularized by Sutskever et al. in the field of machine translation in 2014. Its significance lies in learning features from the data based entirely on the data itself, and compared to other abstract summarization methods Can get better results. In the paper published in 2015, Rush et al. combined the neural language model and the context-based input encoder to propose a sentence summarization model based on the encoder-decoder framework, which generates summaries one by one given the input sentence. of each word. Lopyrev et al. used LSTM as the model of the encoder-decoder framework, and used the attention model to generate the headline...
