A MWE lexicon formalism optimised for observational adequacy

Anonymous

Abstract: Past research advocates that, in order to handle the unpredictable nature of multiword expressions (MWEs), their identification should be assisted with lexicons.The choice of the format for such lexicons, however, is far from obvious. We propose the first -- to our knowledge -- method to quantitatively evaluate MWE lexicon formalisms based on the notion of observational adequacy. We apply it to derive a simple yet adequate MWE-lexicon formalism, dubbed $\lambda$-CSS, based on syntactic dependencies. It proves competitive with lexicons based on sequential representation of MWEs, as well as with a state-of-the art MWE identifier.
