摘要： 专利说明书含有大量有用的信息,但由于篇幅很长,人们很难快速获取其中的有效信息。专利摘要是对一份完整专利说明书的总结与概述,权利要求书作为说明书的一部分,其记载的内容确定了专利申请文件的保护范围,含有专利文献的主要信息。同时经研究发现,专利的权利要求书具有特殊的结构。因此,提出了一种基于图卷积网络的专利摘要自动生成方法,旨在通过专利的权利要求书及其结构信息来生成专利摘要。该方法首先获取权利要求书中的结构信息,在编码阶段引入图卷积神经网络来融合语义信息和结构信息,从而生成高质量的专利摘要。实验结果表明,与目前主流的抽取式摘要方法和传统的编码器-解码器生成方法相比,该方法在ROUGE评价指标上有显著提高。
