ABSAPapers

Must-read papers and related awesome resources on aspect-based sentiment analysis (ABSA). This repository mainly focused on aspect-term sentiment classification (ATSC). ABSA task contains five fine-grained subtasks:

Aspect Term Sentiment Classification (ATSC)
Aspect Term Extraction (ATE)
Aspect Category Sentiment Classification (ACSC)
Aspect Category Detection (ACD)
Opniton Term Extraction (OTE)

Suggestions about adding papers, repositories and other resource are welcomed!

Multi-task Learning

Combining two or more ABSA's subtasks in one framework to produce results is an intutively effective way for industrial application. There are two patterns of multi-task learning: pipeline and joint model. For pipeline pattern, the framework complete subtasks in more than one step, using the result of last step to guide the next step's output, which might lead to error propogation problem. Joint model processes the data with shared layers to extract universal semantic features for all subtasks. Then model outputs results of different tasks through task-specific layers.
