This paper proposes a exible matching method that can assimilate the expressive divergence. First, broad-coverage syn- onymous expressions are automatically ex- tracted from an ordinary dictionary, and among them, those whose distributional similarity in a Web corpus is high are used forthe exiblematching. Then, toovercome the combinatorial explosion problem in the combination of expressive divergence, an ID is assigned to each synonymous group, and SYNGRAPH data structure is introduced to pack the expressive divergence. We con- rmed the effectiveness of our method on experiments of machine translation and in- formation retrieval.
