Abstract

This paper describes a system that resolves prepositional
phrase attachment ambiguity in English sentence process-
ing. This attachment problem is ubiquitous in English
text, and is widely known as a place where semantics
determines syntactic form. The decision is made based on
a four-tuple composed of the head verb of the verb phrase,
the head noun of the noun phrase, and the preposition
and head noun in the prepositional phrase. A corpus with
known results, the Penn Treebank, is used for training
and testing purposes. During training, known results are
used to build a lattice of hierarchical categories taken from WordNet. These lattices are then compared to the novel
lattices derived from the test four-tuples. The results of the system are 90.53% correct attachment decisions.
