Opinion-Triplet-Extraction-Papers

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.
