论文摘要
引号提取旨在从书面文本中提取引号。引号中有三个组成部分：来源是指引号的持有人，提示是触发词，内容是主体。引号提取的现有解决方案主要利用基于规则的方法和序列标签模型。尽管基于规则的方法通常会导致召回率低，但序列标记模型不能很好地处理复杂结构的引号。在本文中，我们提出上下文和以前的标签增强网（Cofenet），以提取引号。 Cofenet能够提取具有可变长度和复杂结构的组成部分的复杂报价。在两个公共数据集（即polnear和Riqua）和一个专有数据集（即Politicszh）上，我们表明我们的Cofenet在复杂的引号提取方面取得了最先进的表现。
Quotation extraction aims to extract quotations from written text. There are three components in a quotation: source refers to the holder of the quotation, cue is the trigger word(s), and content is the main body. Existing solutions for quotation extraction mainly utilize rule-based approaches and sequence labeling models. While rule-based approaches often lead to low recalls, sequence labeling models cannot well handle quotations with complicated structures. In this paper, we propose the Context and Former-Label Enhanced Net (CofeNet) for quotation extraction. CofeNet is able to extract complicated quotations with components of variable lengths and complicated structures. On two public datasets (i.e., PolNeAR and Riqua) and one proprietary dataset (i.e., PoliticsZH), we show that our CofeNet achieves state-of-the-art performance on complicated quotation extraction.
