Improving Fine-grained Entity Typing with Entity Linking
This work addresses a challenging NLP task for researchers and practitioners, but it is incremental as it builds on existing methods with a hybrid approach.
The paper tackled the problem of fine-grained entity typing by using entity linking to assist classification, achieving over 5% absolute strict accuracy improvement on two datasets.
Fine-grained entity typing is a challenging problem since it usually involves a relatively large tag set and may require to understand the context of the entity mention. In this paper, we use entity linking to help with the fine-grained entity type classification process. We propose a deep neural model that makes predictions based on both the context and the information obtained from entity linking results. Experimental results on two commonly used datasets demonstrates the effectiveness of our approach. On both datasets, it achieves more than 5\% absolute strict accuracy improvement over the state of the art.
