| Abstract(in English) | A new word-clustering rechnique is proposed to efficiently build statistically salient class 2-grams from language corpora. By splitting word neighboring characteristics into word-preceding and following directions, multiple(two-dimensional)word classes are assigned to each word. In each side, word classes are merged into larger clusters independently according to preceding or following word distributions. This word-clustering can provide more efficient and statistically reliable word clusters. Further, we extend it to Multi-Class Composite N-gram that unit is Multi-Class 2-gram and joined word. Multi-Class Composite N-gram showed better performance both in perplexity and recognition rates with one thousandth smaller logical parameter size than conventional word 2-grams. |
