This repository includes papers about the opinion triplet extraction task, which aims to extract (aspect term, sentiment, opinion term) triplets from sentences. The opinion triplet extraction task includes two subtasks: Aspect Sentiment Triplet Extraction (ASTE) and Aspect Sentiment Opinion Triplet Extraction (ASOTE).
- ASTE extracts triplets where the sentiment is the sentiment that the sentence expresses toward the aspect term.
- ASOTE extracts triplets where the sentiment is the sentiment of the (aspect term, opinion term) pair.
There are some relevant tasks:
- ATE (Aspect Term Extraction) extracts aspects from sentences.
- TOWE (Target-oriented Opinion Words Extraction) extracts opinions associated with a given aspect in a sentence.
- ATSA (Aspect Term Sentiment Analysis) predicts the sentiment that a sentence expresses toward a given aspect.
- Aspect-Opinion Pair Sentiment Classification (AOPSC) predicts the sentiment of a (aspect term, opinion term) in a sentence.
An example showing the inputs and outputs of the tasks mentioned above. For each arrow, when the head is a task name, the tail is an input of the task; when the tail is a task name, the head is an output of the task. The bold words are aspects. The underlined words are opinions.
