Query expansion using lexical-semantic relations

by Ellen M. Voorhees - In Proceedings of the 17th Annual International ACM SIGIR Conference on Research and Development in Information Retrieval , 1994
"... Applications such as office automation, news filtering, help facilities in complex systems, and the like require the ability to retrieve documents from full-text databases where vocabulary problems can be particularly severe. Experiments performed on small collections with single-domain thesauri sug ..."

suggest that expanding query vectors with words that are lexically related to the original query words can ameliorate some of the problems of mismatched vocabularies. This paper examines the utility of lexical query expansion in the large, diverse TREC collection. Concepts are represented by Word

The Representation of Lexical Semantic Information

by Ann Copestake - University of Sussex , 1992
"... This thesis is an investigation of the representation of lexical semantic information from a computational linguistic perspective. An implemented representation language is described which is not specic to lexical semantics, but is based on the use of typed feature structures augmented with default ..."

Morphological Cues for Lexical Semantics

by Marc Light , 1996
"... Most natural language processing tasks require lexical semantic information. Automated acquisition of this information would thus increase the robustness and portability of NLP systems. This paper describes an acquisition method which makes use of fixed correspondences between derivational affixes ..."

Evaluating WordNet-based measures of lexical semantic relatedness

by Alexander Budanitsky, Graeme Hirst - Computational Linguistics , 2006
"... The quantification of lexical semantic relatedness has many applications in NLP, and many different measures have been proposed. We evaluate five of these measures, all of which use WordNet as their central resource, by comparing their performance in detecting and correcting real-word spelling error ..."

Polarity sensitivity as lexical semantics

by Michael Israel - Linguistics and Philosophy , 1996
"... Over the last thirty years, the phenomenon of polarity sensitivity has proven both a touchstone and a stumbling block for theories of grammatical representation. Unfortunately, an abundance of scrutiny does not always guarantee an increase in insight. Two major pitfalls are worth mentioning. On the ..."
Abstract - Cited by 43 (2 self) - Add to MetaCart
. This paper seeks to negotiate these dangers by considering polarity sensitivity as a problem in lexical semantics. The basic strategy builds on recent analyses by Krifka (1990, 1994), Kadmon and Landman (1993), and Lee and Horn (1994), all of which offer lexical semantic explanations for the distribution

Contextually-dependent lexical semantics

by Cornelia Maria Verspoor, Cornelia Maria Verspoor , 1997
"... This thesis is an investigation of phenomena at the interface between syntax, semantics, and pragmatics, with the aim of arguing for a view of semantic interpretation as lexicallydriven yet contextually dependent. I examine regular, generative processes which operate over the lexicon to induce verba ..."
Abstract - Cited by 31 (2 self) - Add to MetaCart
verbal sense shifts, and discuss the interaction of these processes with the linguistic or discourse context. I concentrate on phenomena where only an interaction between all three linguistic knowledge sources can explain the constraints on verb use: conventionalised lexical semantic knowledge constrains

Ten Choices for Lexical Semantics

by Sergei Nirenburg, Victor Raskin , 1996
"... The modern computational lexical semantics reached a point in its development when it has become necessary to define the premises and goals of each of its several trends. This paper proposes ten choices in terms of which these premises and goals can be discussed. It is argued that the central que ..."

Impairments of Lexical-Semantic Processing

by unknown authors
"... Broca’s and W ern icke’s aphasics performed speeded lexical decisions on the third member of auditorily presented triplets consisting of two word primes fol lowed by either a word or a nonword. In three of the four priming conditions, the second prime was a homonym with two unrelated meanings. The r ..."
Abstract - Add to MetaCart
effects were obtained at ISIs of 100 and 500 msec, but not at an ISI of 1250 msec. This pattern of results is consistent with the view that both types of aphasics can automatically access the semantic lexi con, but might be impaired in integrating lexical-semantic information into the
