摘　　要：为科技论文生成自动摘要,这能够帮助作者更快撰写摘要,是自动文摘的研究内容之一。相比于常见的新闻文档,科技论文具有文档结构性强、逻辑关系明确等特点。目前,主流的编码-解码的生成式文摘模型主要考虑文档的序列化信息,很少深入探究文档的篇章结构信息。为此,文中针对科技论文的特点,提出了一种基于“单词-章节-文档”层次结构的自动摘要模型,利用单词与章节的关联作用增强文本结构的层次性和层级之间的交互性,从而筛选出科技论文的关键信息。除此之外,该模型还扩充了一个上下文门控单元,旨在更新优化上下文向量,从而能更全面地捕获上下文信息。实验结果表明,提出的模型可有效提高生成文摘在ROUGE评测方法上的各项指标性能。With the development of science and technology,people need to access a large number of scientific and technological information quickly,and scientific paper is one of the main ways to carry scientific and technological information.As an important part of scientific paper,abstract is an effective tool for readers to retrieve literature.Therefore,the quality of abstract affects the retrieval rate of paper directly.However,due to the lack of writing experience,the quality of abstracts written by many authors is not high.Automatic generation of summary for scientific paper can help the author grasp the important content of paper more effectively,so as to write high-quality abstract.At the same time,the automatically generated abstract can also control the number of words in the abstract,which can bring more content to readers and help them understand the paper better.Generating automa-tic summarization for scientific paper can help author write abstract faster,which is one of the research contents in automatic summarization.Compared with common news document,scientific paper has the characteristics of strong structure and clear logical relationship.As far as the mainstream abstractive summarization such as encoder-decoder model is concerned,it mainly consi-ders the serialized information in the document,and rarely explores the text structure information in the document.For this reason,according to the characteristics in scientific papers,this paper proposes an automatic summarization model based on the hie-rarchical structure of“word-section-document”,which uses the association between word and section to enhance the level of text structure and the interaction between levels,so as to screen out the key information in scientific paper.In addition,a context gate unit is extended to update the optimized context vector,thus capturing context information more comprehensively.The experimental results show that the proposed model can effectively improve the performance of the generated summarization in the ROUGE evaluat
