GlobalNER: Incorporating Non-local Information into Named Entity Recognition
This addresses the need for better NER performance in NLP by introducing a novel method for retrieving external knowledge, though it is incremental as it builds on existing techniques like BERTScore.
The paper tackled the problem of improving Named Entity Recognition by incorporating non-local information through query generation and re-ranking, achieving a state-of-the-art micro-f1 score of 61.56 on the WNUT17 dataset.
Nowadays, many Natural Language Processing (NLP) tasks see the demand for incorporating knowledge external to the local information to further improve the performance. However, there is little related work on Named Entity Recognition (NER), which is one of the foundations of NLP. Specifically, no studies were conducted on the query generation and re-ranking for retrieving the related information for the purpose of improving NER. This work demonstrates the effectiveness of a DNN-based query generation method and a mention-aware re-ranking architecture based on BERTScore particularly for NER. In the end, a state-of-the-art performance of 61.56 micro-f1 score on WNUT17 dataset is achieved.
