| Abstract(in English) | PLSA (Probabilistic Latent Semantic Analysis) is one of promising language model adaptation methods. We propose a new way to combine PLSA and N-gram models by separating the vocabulary into three classes-'topic'-related, 'style'-related and 'general'-related words. This method trains topic vocabulary PLSA model, style vocabulary PLSA model, and general vocabulary unigram model independently, and combines the three models. And we propose an automatic composing method of vocabulary divide criterion, using pattern of word-Class occurrence between newspaper and CSJ. The experimental result showed that the proposed method achieves 15.48% perplexity reduction than conventional PLSA model, about testset of which topic and style feature are not happen together in the training data. |
