Chuan‐Jie Lin, Wei‐Cheng Chu · 2015
This paper proposes an automatic method to build a Chinese spelling check system. Confusion sets were expanded by using two language resources, Shuowen Jiezi and the Four-Corner codes, which improved the coverages of the confusion sets. Nine scoring functions which utilize the frequency data in the Google Ngram Datasets were proposed, where the idea of smoothing was also adopted. Thresholds were also decided in an automatic way. The final system achieved far better than our baseline system in CSC 2013 Evaluation Task.
