Question Answering with Lexical Chains Propagating Verb Arguments

  title={Question Answering with Lexical Chains Propagating Verb Arguments},

This paper describes an algorithm for propagating verb arguments along lexical chains consisting of WordNet relations. The algorithm creates verb argument structures using VerbNet syntactic patterns. In order to increase the coverage, a larger set of verb senses were automatically associated with the existing patterns from VerbNet.
