Xinhong Chen, Zongxi Li, Yaowei Wang, Haoran Xie, Jianping Wang, Qing, Li

TL;DR
This paper introduces a new task to identify whether emotion-cause pairs are causally related under specific contexts, along with extracting relevant context clauses, supported by a new annotated dataset and an effective multi-task framework.
Contribution
It proposes the first framework for detecting context-dependent causal relationships between emotions and causes, with a new dataset and novel modules for context extraction and prediction refinement.
Findings
The framework effectively identifies context-dependent causal relationships.
The proposed modules improve the accuracy of causal relationship detection.
Extensive experiments validate the approach's effectiveness and generality.
Abstract
The study of causal relationships between emotions and causes in texts has recently received much attention. Most works focus on extracting causally related clauses from documents. However, none of these works has considered that the causal relationships among the extracted emotion and cause clauses can only be valid under some specific context clauses. To highlight the context in such special causal relationships, we propose a new task to determine whether or not an input pair of emotion and cause has a valid causal relationship under different contexts and extract the specific context clauses that participate in the causal relationship. Since the task is new for which no existing dataset is available, we conduct manual annotation on a benchmark dataset to obtain the labels for our tasks and the annotations of each context clause's type that can also be used in some other applications.…
