摘要:【中文】本发明公开了一种基于注意力机制生成摘要的方法来生成文本摘要,本发明一共包括两个阶段:第一个阶段是句子排序过程,第二阶段是摘要生成过程,其输入是通过第一阶段得到的与文章主题最相关的N个句子。在第一阶段中,对于带有标题的文章本文提出一种监督式的排序方法,首先计算每一个句子与标题之间相似度,再根据相似度对文章进行排序,最后选取相似度最高的N个句子。对于第二阶段,本发明提出了一种新的计算编码器和解码器之间注意分布的方法,即在不同时间里,解码器应该关注编码器中的不同部分。本发明通过排序方法和摘要生成方法,缓解了文章过长时必须直接截断一部分文本作为摘要生成模型的输入所导致的文章信息衰减问题。 【EN】The invention discloses a method for generating an abstract based on an attention mechanism to generate a text abstract, which comprises two stages in total: the first stage is a sentence ordering process and the second stage is a summary generation process, and the input of the summary generation process is the N sentences which are most relevant to the article topics and obtained by the first stage. In the first stage, a supervised sorting method is provided for articles with titles, similarity between each sentence and the title is calculated, the articles are sorted according to the similarity, and finally N sentences with the highest similarity are selected. For the second stage, the present invention proposes a new way of calculating the attention distribution between the encoder and the decoder, i.e. at different times the decoder should focus on different parts of the encoder. The invention solves the problem of article information attenuation caused by directly truncating a part of text as the input of the abstract generation model when the article is too long through the sorting method and the abstract generation method.
