Abstract
“The purpose of Aspect Sentiment Triplet Extraction (ASTE) is to extract a triplet, including thetarget or aspect, its associated sentiment, and related opinion terms that explain the underlyingcause of the sentiment. Some recent studies fail to capture the strong interdependence betweenATE and OTE, while others fail to effectively introduce the relationship between aspects andopinions into sentiment classification tasks. To solve these problems, we construct a multi-roundmachine reading comprehension framework based on a rethink mechanism to solve ASTE tasksefficiently. The rethink mechanism allows the framework to model complex relationships be-tween entities, and exclusive classifiers and probability generation algorithms can reduce queryconflicts and unilateral drops in probability. Besides, the multi-round structure can fuse explicitsemantic information flow between aspect, opinion and sentiment. Extensive experiments showthat the proposed model achieves the most advanced effect and can be effectively applied toASTE tasks.”
