An approach to take multi-word expressions

Abstract

This research discusses preliminary efforts to expand the coverage of the PropBank lexicon to multi-word and idiomatic expressions, such as take one for the team. Given overwhelming numbers of such expressions, an efficient way for increasing coverage is needed. This research discusses an approach to adding multi-word expressions to the PropBank lexicon in an effective yet semantically rich fashion. The pilot discussed here uses double annotation of take multi-word expressions, where annotations provide information on the best strategy for adding the multi-word expression to the lexicon. This work represents an important step for enriching the semantic information included in the PropBank corpus, which is a valuable and comprehensive resource for the field of Natural Language Processing.
