论文摘要
情绪原因对提取（ECPE）是一项新的任务，旨在从文档中提取潜在的情绪和相应原因。先前的方法重点是建模成对的关系并取得了令人鼓舞的结果。但是，从根本上象征文档的基本结构的条款与差异关系仍处于研究期。在本文中，我们定义了一个新的条款与差异关系。为了学习它，我们提出了一个名为EA-GAT的一般条款级编码模型，该模型包括E-GAT和激活排序。 E-GAT旨在从不同类型的子句中汇总信息；激活排序利用个人情感/原因预测和基于排序的映射将条款推向更有利的表示。由于ea-gat是一个子句级的编码模型，因此可以将其与任何以前的方法广泛集成。实验结果表明，我们的方法比当前的所有方法在中文和英语基准语料库中都具有显着优势，平均$ 2.1 \％$和$ 1.03 \％$ $。
Emotion-cause pair extraction (ECPE) is an emerging task aiming to extract potential pairs of emotions and corresponding causes from documents. Previous approaches have focused on modeling the pair-to-pair relationship and achieved promising results. However, the clause-to-clause relationship, which fundamentally symbolizes the underlying structure of a document, has still been in its research infancy. In this paper, we define a novel clause-to-clause relationship. To learn it applicably, we propose a general clause-level encoding model named EA-GAT comprising E-GAT and Activation Sort. E-GAT is designed to aggregate information from different types of clauses; Activation Sort leverages the individual emotion/cause prediction and the sort-based mapping to propel the clause to a more favorable representation. Since EA-GAT is a clause-level encoding model, it can be broadly integrated with any previous approach. Experimental results show that our approach has a significant advantage over all current approaches on the Chinese and English benchmark corpus, with an average of $2.1\%$ and $1.03\%$.
