摘要:

从非结构化文本文档中提取信息是一项要求很高的任务,因为这些文档可能具有各种不同的布局和非平凡的阅读顺序,就像多列文档或嵌套表的情况一样。此外,许多业务文档都是以纸质形式收到的,这意味着在进一步分析之前需要将文本内容数字化。尽管如此,自动检测和捕获发件人地址等关键文档信息将提高许多公司的处理效率。在这项工作中,我们提出了一种混合的方法,结合深度学习与推理,从非结构化文本文档中查找和提取地址。我们使用视觉深度学习模型来检测扫描文档图像上可能的地址区域的边界,并通过使用表示为基于规则的系统的领域知识分析包含的文本来验证这些结果。

英文摘要:

Extracting information from unstructured text documents is a demanding task, since these documents can have a broad variety of different layouts and a non-trivial reading order, like it is the case for multi-column documents or nested tables. Additionally, many business documents are received in paper form, meaning that the textual contents need to be digitized before further analysis. Nonetheless, automatic detection and capturing of crucial document information like the sender address would boost many companies' processing efficiency. In this work we propose a hybrid approach that combines deep learning with reasoning for finding and extracting addresses from unstructured text documents. We use a visual deep learning model to detect the boundaries of possible address regions on the scanned document images and validate these results by analyzing the containing text using domain knowledge represented as a rule based system.
