Chinese NER by Span-Level Self-Attention

2019 15th International Conference on Computational Intelligence and Security (CIS), 2019
In this paper, we investigate how to improve Chinese named entity recognition (NER) by applying self-attention mechanism on span-level semantic representations. Specifically, we propose a model which acquires character representations through pre-trained BERT, then extracts features of each possible character-span through LSTM, estimates the semantic ...

Chinese NER Using ALBERT and Multi-word Information

ACM Turing Award Celebration Conference - China ( ACM TURC 2021), 2021
Recently, many Chinese Named Entity Recognition (NER) problems which utilize the character-based approach have a good performance, the character-based approach becomes the dominant current of the approaches, but there are two issues in the existing models.

ESN-NER

Proceedings of the International Conference on Artificial Intelligence, Information Processing and Cloud Computing, 2019
Chinese named entity recognition (NER) is more difficult than it in English because of the lack of nature delimiters. First, Chinese NER requires word segmentation, but word-based segmentation will generate errors due to the different granularity of the word segmentation tools.
