Syntactic and Semantic Features For Code-Switching Factored Language Models
TABLE IV: PPL of FLMs with Brown word clusters, POS tags and LID
['Model', 'PPL dev', 'PPL eval']
Brown word clusters with 70 classes are first investigated as the only factor besides words. Then, they are combined with the factors POS tags and LID. The results show that the combination of Brown word clusters and POS tags leads to the best word prediction results on the CS text. The additional integration of LID does not improve the results.
