Knowing What, How and Why: A Near Complete Solution for Aspect-based Sentiment Analysis

Understand

Target-based sentiment analysis or aspect-based sentiment analysis (ABSA) refers to addressing various sentiment analysis tasks at a fine-grained level, which includes but is not limited to aspect extraction, aspect sentiment classification, and opinion extraction.

• There exist many solvers of the above individual subtasks or a combination of two subtasks, and they can work together to tell a complete story, i.e.
• the discussed aspect, the sentiment on it, and the cause of the sentiment.
• However, no previous ABSA research tried to provide a complete solution in one shot.
