Resolving Prepositional Phrase Attachment Ambiguity Using Conceptual Information

Resolving a Pragmatic Prepositional Phrase Attachment Ambiguity

1. Introduction To resolve or not to resolve, that is the structural ambiguity dilemma. The traditional wisdom is to disambiguate only when it matters in terms of the meaning of the utterance, and to do so using the computationally least costly information. NLP work on PP-attachment has followed this wisdom, and much effort has been focused on formulating structural and lexical strategies for r...

Prepositional phrase attachment ambiguity resolution using word sense hierarchies

Prepositional Phrase Attachment Ambiguity Resolution Using Semantic Hierarchies

This paper describes a system that resolves prepositional phrase attachment ambiguity in English sentence processing. 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 hea...

Resolving prepositional phrase attachment ambiguities in Spanish with a classifier

In this paper we present a classifier that solves a certain kind of ambiguities in syntactic structure for Spanish, namely, ambiguities as to the point of adjunction of a prepositional phrase in the syntactic structure of a sentence (PP attachment). As a starting point, we used EsTxala dependency grammar for Spanish, integrated within FreeLing, with an accuracy score of 61% on PP adjunction. Ou...

A Neurocomputational Approach to Prepositional Phrase Attachment Ambiguity Resolution

A neurocomputational model based on emergent massively overlapping neural cell assemblies (CAs) for resolving prepositional phrase (PP) attachment ambiguity is described. PP attachment ambiguity is a well-studied task in natural language processing and is a case where semantics is used to determine the syntactic structure. A large network of biologically plausible fatiguing leaky integrate-and-...
