Abstract

We study the task of automatically disambiguating word combinations such as jump the gun which are ambiguous between a literal and MWE interpretation, focusing on the utility of type-level features from an MWE lexicon for the disambiguation task. To this end we combine gold-standard idiomaticity of tokens in the OpenMWE corpus with MWE-type-level information drawn from the recently-published JDMWE lexicon. We find that constituent modifiability in an MWE-type is more predictive of the idiomaticity of its tokens than other constituent characteristics such as semantic class or part of speech.
