Lexical Ambiguity and Information Retrieval
- ACM TRANSACTIONS ON INFORMATION SYSTEMS
, 2000
"... Lexical ambiguity is a pervasive problem in natural language processing. However, little quantitative information is available about the extent of the problem, or about the impact that it has on information retrieval systems. We report on an analysis of lexical ambiguity in information retrieval ..."

Lexical ambiguity is a pervasive problem in natural language processing. However, little quantitative information is available about the extent of the problem, or about the impact that it has on information retrieval systems. We report on an analysis of lexical ambiguity in information retrieval
Resolving Lexical Ambiguity Computationally With Spreading

Lexical Ambiguity in Medical Documents
"... In biomedicine the amount of published material has been growing exponentially in recent years, particularly in very productive areas, such as genomics. However, automatic processing of these documents is hampered by the fact that texts in the biomedical domain, like those in other areas, contain a ..."

range of lexical ambiguities. Studies have shown ~12 % of the terms in MEDLINE citations are semantically ambiguous (may refer to more than one UMLS concept) (Weeber et. al., 2001). The aim of the BioWSD project is to develop tools and algorithms to resolve various forms of lexical ambiguity found
IDENTIFIERS *Lexical Ambiguity
"... This study investigates the role of specific inhibitory processes in lexical ambiguity resolution. An attentional view of inhibition and a view based on specific automatic inhibition between nodes predict different results when a neutral item is processed between an ambiguous word and a related targ ..."

Lexical Ambiguity as Type Disjunction
"... Phenomena such as logical polysemy and logical metonymy have recently received a precise treat-ment by using a rich composition logic that assumes complex types and rich introduction and exploita-tion rules for manipulating them (Asher and Puste-jovsky, 2005). An interesting question is whether this ..."

this approach can be extended and applied to other lexical semantics phenomena, in particular to con-trastive ambiguity (aka homonymy). This paper en-riches Asher and Pustejovsky’s Type Composition Logic with another type of complex types, namely disjunctive types, and accompanying exploitation and introduction
Parsing Against Lexical Ambiguity
"... Marcus' original deterministic parsing included almost no part-of-speech ambiguity. In this paper, the addition of part-of-speech ambiguity to a deterministic parser written in Prolog is described. To handle this ambiguity, it was necessary to add no special mechanisms to the parser. Instead ..."

Comparing Corpora and Lexical Ambiguity
"... In this paper we compare two types of corpus, focusing on the lexical atnbiguity of each of them. The first corpus consists mainly of newspaper articles and literature excerpts, while the second belongs to the medical domain. To conduct the'. study, we have used two different disambiguati ..."

THE LOGICAL ANALYSIS OF LEXICAL AMBIGUITY
"... Theodes of semantic interpretation which wish to capture as many generalizations as possible must face up to the manifoldly ambiguous and contextually dependent nature of word meaning? In this paper I present a two-level scheme of semantic interpretation in which the first level deals with the seman ..."

Lexical ambiguity and Information Retrieval revisited
