摘要:

由于现实世界中无处不在的文档(例如,发票、票证、简历和传单)包含着丰富的信息,文档图像的自动理解已经成为一个热门话题。大多数现有的作品解耦的问题分为两个独立的任务,(1)文本阅读检测和识别图像中的文本和(2)信息抽取分析和提取的关键元素,从以前提取的纯文本。然而,他们主要集中在提高信息抽取任务,而忽略了文本阅读和信息抽取是相互关联的事实。在本文中,我们提出了一个统一的端到端的文本阅读和信息抽取网络,其中这两个任务可以相互加强。具体地说,文本阅读的多模态视觉和文本特征被融合用于信息抽取,而信息抽取中的语义有助于文本阅读的优化。在三个具有不同文档图像的真实世界数据集上(从固定布局到可变布局,从结构化文本到半结构化文本),我们提出的方法在效率和准确性方面都显着优于最先进的方法。

英文摘要:

Since real-world ubiquitous documents (e.g., invoices, tickets, resumes and leaflets) contain rich information, automatic document image understanding has become a hot topic. Most existing works decouple the problem into two separate tasks, (1) text reading for detecting and recognizing texts in images and (2) information extraction for analyzing and extracting key elements from previously extracted plain text. However, they mainly focus on improving information extraction task, while neglecting the fact that text reading and information extraction are mutually correlated. In this paper, we propose a unified end-to-end text reading and information extraction network, where the two tasks can reinforce each other. Specifically, the multimodal visual and textual features of text reading are fused for information extraction and in turn, the semantics in information extraction contribute to the optimization of text reading. On three real-world datasets with diverse document images (from fixed layout to variable layout, from structured text to semi-structured text), our proposed method significantly outperforms the state-of-the-art methods in both efficiency and accuracy.
