Research Abstract

We proposed a method that organizes technical terms by their properties, and confirmed its effectiveness by experiments. Using this method, we constructed a thesaurus from 20,000,000 sentences in unexamined Japanese patent applications published during 1993-2002. We also improved a system that creates technical trend map from a set of technical documents using this method.
