“In Chinese Named Entity Recognition, character substitution is a complicated linguistic phe-nomenon. Some Chinese characters are quite similar as they share the same components or havesimilar pronunciations. People replace characters in a named entity with similar characters togenerate a new collocation but refer to the same object. As a result, it always leads to unrecog-nizable or mislabeling errors in the NER task. In this paper, we propose a lightweight method,MFE-NER, which fuses glyph and phonetic features to help pre-trained language models handlethe character substitution problem in the NER task with limited extra cost. Basically, in the glyphdomain, we disassemble Chinese characters into Five-Stroke components to represent structurefeatures. In the phonetic domain, an improved phonetic system is proposed in our work, makingit reasonable to describe phonetic similarity among Chinese characters. Experiments demon-strate that our method performs especially well in detecting character substitutions while slightlyimproving the overall performance of Chinese NER.”
