| Challenge: | Existing crowd annotation tools for named entity recognition (NER) focus on efficiency and don't consider consistency of datasets. |
| Approach: | They propose a crowd annotation platform for Chinese named entity recognition (NER) CroAno provides a systematic solution for improving label consistency of Chinese NER datasets. |
| Outcome: | The proposed platform improves label consistency of Chinese NER datasets. |
A Lexicon-Based Graph Neural Network for Chinese NER (D19-1)
Copied to clipboard
| Challenge: | Chinese named entity recognition models are vulnerable to word ambiguities due to the lack of global semantics and chain structure. |
| Approach: | They propose a lexicon-based graph neural network with global semantics to solve word ambiguities in Chinese named entity recognition (NER) Lexicons are used to construct the graph and provide word-level features. |
| Outcome: | The proposed model improves on four NER datasets on Chinese characters, potential words, and the whole-sentence semantics. |
Adaptive Threshold Selective Self-Attention for Chinese NER (2022.coling-1)
Copied to clipboard
| Challenge: | Named entity recognition (NER) is a computationally difficult task in Chinese since there is no natural delimiter between words in sentences. |
| Approach: | They propose a data-driven Adaptive Threshold Selective Self-Attention mechanism to select the most relevant characters to enhance Transformer architecture for Chinese named entity recognition. |
| Outcome: | Experiments on four benchmark Chinese NER datasets show the proposed mechanism improves performance. |
Distantly Supervised NER with Partial Annotation Learning and Reinforcement Learning (C18-1)
Copied to clipboard
| Challenge: | Existing approaches to named entity recognition (NER) in Chinese are limited by the lack of annotated data. |
| Approach: | They propose a method which can automatically populate annotated training data without humancost by using distant supervision. |
| Outcome: | The proposed method performs better than comparison systems on two datasets. |
Simplify the Usage of Lexicon in Chinese NER (2020.acl-main)
Copied to clipboard
| Challenge: | Named entity recognition (NER) is concerned with the identification of named entities in unstructured text. |
| Approach: | They propose a method for incorporating word lexicon into character representations . experimental results show method can be easily incorporated with pre-trained models . |
| Outcome: | The proposed method achieves 6.15 times faster inference speed and better performance on four benchmark Chinese NER datasets. |
FLAT: Chinese NER Using Flat-Lattice Transformer (2020.acl-main)
Copied to clipboard
| Challenge: | Named entity recognition (NER) models are difficult to use because of the complex nature of the lattice structure and the low inference speed. |
| Approach: | They propose a character-word lattice structure that converts lattics into flat structures consisting of spans. |
| Outcome: | The proposed model outperforms other lexicon-based models on four datasets and is highly parallel. |
