Prepositional Phrase Attachment Ambiguity Resolution Using Semantic Hierarchies
نویسندگان
چکیده
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 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.

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-...

This study examined whether processing ambiguous sentences containing relative clauses (RCs) following a complex determiner phrase (DP) by Persian-speaking learners of L2 English with different proficiency and working memory capacities (WMCs) is affected by semantic priming. The semantic relationship studied was one between the subject/verb of the main clause and one of the DPs in the complex D...
متن کاملA Rule-Based and MT-Oriented Approach to Prepositional Phrase Attachment
Prepositional Phrase is the key issue in structural ambiguity. Recently, researches in corpora provide the lexical cue of prepositions with other words and the information could be used to partly resolve ambiguity resulted from prepositional phrases. Two possible attachments are considered in the literature: either noun attachment or verb attachment. In this paper, we consider the problem from ...
متن کاملA “Random Walk” through Prepositional Phrase Attachment
This document surveys the field of research in preposition phrase attachment resolution, looking back at the way the problem was approached in the 1990s, as well as at modern techniques for resolving this basic syntactic ambiguity problem. Techniques are described and compared, and their effectiveness is considered.
