Referent graph embedding model for name entity recognition of Chinese car reviews

作者：

Highlights：

• This paper proposes an RGE-NER model to solve the NER problem for Chinese car reviews. The model innovatively combines referent graph and deep learning models.

• Word-based and pronunciation-based methods are designed to expand the index range of entities in lexicon, which reduces the impact of irregular text expressions.

• The latest BERT-based character vectors and the character-level candidate entities are jointly embedded into the deep learning model to perform the NER.

• The embedding weights of candidate entities are measured by exploiting the global interdependence between candidate entities instead of algorithm learning, which significantly reduces the time complexity while improving the model performance.
