| Abstract : | Knowledge of which words are able to fill p~rtic-ular argum.ent slots of a predicate can be used tbr structural disambiguation. This paper de-scribes a proposal:for acquiring such knowledge, and in line with much of the recent work in this area, a probabilistic approach is taken. We de-velop a novel way of using a semantic hierar-chy to estimate the probabilities, and demon-strate the general approach using a preposi-, |
