摘要:

推理-原因对抽取(ECPE)的任务是抽取文档中所有潜在的情感小句对及其对应的原因。不像更好的研究任务的情绪原因提取(ECE),ECPE不需要情绪子句提供的注释。以前的ECPE工作要么遵循多阶段的方法,其中情感提取,原因提取和配对是独立完成的,要么使用复杂的架构来解决其局限性。在本文中,我们提出了一个端到端的ECPE任务模型。由于英语ECPE语料库的不可用,我们适应NTCIR-13 ECE语料库,并建立一个基线的ECPE任务在这个数据集上。在这个数据集上,所提出的方法比多阶段方法产生了显着的性能改进(F1分数增加约6.5),并实现了与最先进方法相当的性能。

英文摘要:

The task of Emotion-Cause Pair Extraction (ECPE) aims to extract all potential clause-pairs of emotions and their corresponding causes in a document. Unlike the more well-studied task of Emotion Cause Extraction (ECE), ECPE does not require the emotion clauses to be provided as annotations. Previous works on ECPE have either followed a multi-stage approach where emotion extraction, cause extraction, and pairing are done independently or use complex architectures to resolve its limitations. In this paper, we propose an end-to-end model for the ECPE task. Due to the unavailability of an English language ECPE corpus, we adapt the NTCIR-13 ECE corpus and establish a baseline for the ECPE task on this dataset. On this dataset, the proposed method produces significant performance improvements (~6.5 increase in F1 score) over the multi-stage approach and achieves comparable performance to the state-of-the-art methods.
