Abstract

We present a model of human sentence processing that extends a standard probabilistic grammar model with a semantic module which computes the thematic t of verbs and arguments in a cognitively plausible way. Our model differs from existing probabilistic accounts (e.g., Jurafsky, 1996) by capturing both syntactic and semantic inuences in human sentence processing. It also overcomes limitations of constraint-based models (Spivey-Knowlton, 1996; Narayanan and Jurafsky, 2002), as its parameters can be acquired automatically from corpus data, and no hand-coding of constraints is required. We evaluate
our semantic module against human ratings of thematict,and also test the complete model's performance for two wellstudied ambiguities from the sentence processing literature.
