本文提出了一种基于语法关系的叙词表构建方法，该方法采用层次聚类算法构建叙词表。本文的一个重要观点是，为了提高叙词表的效率，需要考虑（表面）案例信息。我们将叙词表称为“基于关系的叙词表（RBT）”。023个动名同现词，并根据客观标准对每一个RBT进行评价。实验表明，RBT比常规RBT具有更好的格框选择性限制特性。
We propose a method to build thesauri on the basis of grammatical relations The proposed method constructs thesaun by using a hierarchical clustering algorithm An important point in this paper is the claim that thesauri in order to be efficient need to take (surface) case information into account We refer to the thesauri as 'relation-based thesaurus (RBT)' In the experiment four RBTs of Japanese nouns were constructed from 26,023 verb-noun cooccurrences, and each RBT was evaluated fry objective criteria The experiment has shown that the RBTs have better properties for selectional restriction of case frames than conventional ones.
