The sense of a preposition is related to the semantics of its dominating prepositional phrase. Knowing the sense of a prepo- sition could help to correctly classify the semantic role of the dominating preposi- tional phrase and vice versa. In this pa- per, we propose a joint probabilistic model for word sense disambiguation of preposi- tions and semantic role labeling of prepo- sitional phrases. Our experiments on the PropBank corpus show that jointly learn- ing the word sense and the semantic role leads to an improvement over state-of-the- art individual classifier models on the two tasks.
