ABSTRACT
Knowledge of which words are able to fill particular argument slots of a predicate can be used for structural disambiguation. This paper describes a proposal for acquiring such knowledge, and in line with much of the recent work in this area, a probabilistic approach is taken. We develop a novel way of using a semantic hierarchy to estimate the probabilities, and demonstrate the general approach using a prepositional phrase attachment experiment.

Class Based Sense Definition Model for word sense tagging and disambiguation
SIGHAN '03: Proceedings of the second SIGHAN workshop on Chinese language processing - Volume 17We present an unsupervised learning strategy for word sense disambiguation (WSD) that exploits multiple linguistic resources including a parallel corpus, a bilingual machine readable dictionary, and a thesaurus. The approach is based on Class Based ...
An endogeneous corpus-based method for structural noun phrase disambiguation
EACL '93: Proceedings of the sixth conference on European chapter of the Association for Computational LinguisticsIn this paper, we describe a method for structural noun phrase disambiguation which mainly relies on the examination of the text corpus under analysis and doesn't need to integrate any domain-dependent lexico- or syntactico-semantic information. This ...
Word vs. class-based word sense disambiguation
As empirically demonstrated by the Word Sense Disambiguation (WSD) tasks of the last SensEval/SemEval exercises, assigning the appropriate meaning to words in context has resisted all attempts to be successfully addressed. Many authors argue that one ...
