This paper describes an algorithm for propagating verb arguments along lexi- cal chains consisting of WordNet rela- tions. The algorithm creates verb argu- ment structures using VerbNet syntactic patterns. In order to increase the cover- age, a larger set of verb senses were auto- matically associated with the existing pat- terns from VerbNet. The algorithm is used in an in-house Question Answering sys- tem for re-ranking the set of candidate an- swers.
