Admitting that admitting verb sense into corpus analyses makes sense

Linguistic and psycholinguistic research has documented that there exists a close relationship between a verb's meaning and the syntactic structures in which it occurs, and that learners and comprehenders take advantage of this relationship both in acquisition and in processing. We address implications of these facts for issues in structural ambiguity resolution, arguing that comprehenders are sensitive to meaning-structure correlations based not on the verb itself but on its specific senses, and that they exploit this information on-line. We demonstrate that individual verbs show significant differences in their subcategorisation profiles across three corpora, and that cross-corpora bias estimates are much more stable when sense is taken into account. Finally, we show that consistency between sense-contingent subcategorisation biases and experimenters' classifications largely predicts results of recent experiments. Thus comprehenders learn and exploit meaning-form correlations at the level of individual verb senses, rather than the verb in the aggregate.
