摘要: 本文給出了一種將詞類信息融入三元文法模型的漢語組合語言模型。理論分析和實驗均表明:該模型不僅復雜度低于三元文法模型,而且對測試文本域的依賴性也優(yōu)于前者。Abstract: A kind of Chinese combined language model,that takes into account POS(part of speech)information in a trigram-based statistical language model, is presented in this paper. The theoretical analysis and experiments all show that the model not only is lower than trigram model in PP(perplexity), but also is superior to trigram model in dependence on test text domain.
