The bigram language models are popular, in much language processing applications, in both Indo-European and Asian languages. However, when the language model for Chinese is applied in a novel domain, the accuracy is reduced significantly, from 96% to 78% in our evaluation. We apply pattern recognition techniques (i.e. Bayesian, decision tree and neural network classifiers) to discover language model errors. We have examined 2 general types of features: model- based and language-specific features. In our evaluation, Bayesian classifiers produce the best recall performance of 80% but the precision is low (60%). Neural network produced good recall (75%) and precision (80%) but both Bayesian and Neural network have low skip ratio (65%). The decision tree classifier produced the best precision ...
