Contextual Similarity is More Valuable than Character Similarity: An Empirical Study for Chinese Spell Checking. (arXiv:2207.09217v2 [cs.CL] UPDATED)

Chinese Spell Checking (CSC) task aims to detect and correct Chinese spelling
errors. In recent years, related researches focus on introducing the character
similarity from confusion set to enhance the CSC models, ignoring the context
of characters that contain richer information. To make better use of contextual
similarity, we propose a simple yet effective curriculum learning framework for
the CSC task. With the help of our designed model-agnostic framework, existing
CSC models will be trained from easy to difficult as …
