摘要

[Abstract]In all fields of Natural Language Process,sentence similarity computation acts an important role. This paper introduces a dependency syntactic tree similarity computation method based on predicate-argument structures. The method treats predicate-argument structures as the research object and studies many features of dependency syntactic tree including word and word`s POS of each node and the dependency type between them. Then the similarity algorithm is proposed after comprehensively analyzing all the features of the predicate-argument structures. The experiment result is satisfied as this method describes dependency syntactic tree more comprehensively and accurately.
