Label-Guided relation prototype generation for Continual Relation Extraction.
PeerJ Comput Sci
October 2024
Article Synopsis
- Continual relation extraction (CRE) focuses on extracting relationships as new data continuously arrives, addressing issues such as catastrophic forgetting.
- Some existing methods use memory replay by storing historical instances or averaging hidden representations, but they fail to fully utilize the semantic information in relation labels and are limited by memory constraints.
- The proposed Label-Guided Relation Prototype Generation enhances label representations and employs a multi-head attention mechanism to create better relation prototypes, along with a new loss function to preserve knowledge from previous tasks, leading to competitive performance in CRE.
