Query: MFE-NER: Multi-feature Fusion Embedding for Chinese Named Entity
  Recognition   Pre-trained language models lead Named Entity Recognition (NER) into a new
era, while some more knowledge is needed to improve their performance in
specific problems. In Chinese NER, character substitution is a complicated
linguistic phenomenon. Some Chinese characters are quite similar for sharing
the same components or having similar pronunciations. People replace characters
in a named entity with similar characters to generate a new collocation but
referring to the same object. It becomes even more common in the Internet age
and is often used to avoid Internet censorship or just for fun. Such character
substitution is not friendly to those pre-trained language models because the
new collocations are occasional. As a result, it always leads to unrecognizable
or recognition errors in the NER task. In this paper, we propose a new method,
Multi-Feature Fusion Embedding for Chinese Named Entity Recognition (MFE-NER),
to strengthen the language pattern of Chinese and handle the character
substitution problem in Chinese Named Entity Recognition. MFE fuses semantic,
glyph, and phonetic features together. In the glyph domain, we disassemble
Chinese characters into components to denote structure features so that
characters with similar structures can have close embedding space
representation. Meanwhile, an improved phonetic system is also proposed in our
work, making it reasonable to calculate phonetic similarity among Chinese
characters. Experiments demonstrate that our method improves the overall
performance of Chinese NER and especially performs well in informal language
environments.
