摘要:

情感原因提取是一项旨在从文本中提取情感背后潜在原因的任务,由于其广泛的应用,近年来受到了广泛的关注。然而,该方法存在两个不足:1)在ECE中提取原因之前必须先对情感进行标注,这极大地限制了其在现实场景中的应用; 2)先标注情感再提取原因的方法忽略了情感和原因是相互指示的事实。在这项工作中,我们提出了一个新的任务:情绪-原因对提取(ECPE),其目的是提取潜在的情绪和相应的原因在一个文件。我们提出了一个两步的方法来解决这个新的ECPE任务,首先通过多任务学习执行个人情感提取和原因提取,然后进行情感-原因配对和过滤。在一个基准情感原因语料库上的实验结果证明了ECPE任务的可行性以及该方法的有效性。

英文摘要:

Emotion cause extraction (ECE), the task aimed at extracting the potential causes behind certain emotions in text, has gained much attention in recent years due to its wide applications. However, it suffers from two shortcomings: 1) the emotion must be annotated before cause extraction in ECE, which greatly limits its applications in real-world scenarios; 2) the way to first annotate emotion and then extract the cause ignores the fact that they are mutually indicative. In this work, we propose a new task: emotion-cause pair extraction (ECPE), which aims to extract the potential pairs of emotions and corresponding causes in a document. We propose a 2-step approach to address this new ECPE task, which first performs individual emotion extraction and cause extraction via multi-task learning, and then conduct emotion-cause pairing and filtering. The experimental results on a benchmark emotion cause corpus prove the feasibility of the ECPE task as well as the effectiveness of our approach.
