Electrophysiological investigations of lexical ambiguity resolution
… I took advantage of a very common phenomenon, lexical ambiguity, to address the question of how human brains resolve the one-to-many mapping problems in language comprehension (e.g. whether the word 'watch' should be interpreted as a timing device or an action). Specifically, in a series of …

Design and evaluation of a method to reduce the lexical ambiguity of requirement specifications
… primary cause of being over-time or over-budget. Ambiguity is a requirement defect that is commonly associated with challenged IT projects, however there are but few empirical studies on how ambiguity can be reduced or eliminated from requirement specifications. Eliminating the ambiguity inherent …

Effects of efficient fronto-temporal circuitry on lexical ambiguity resolution: converging evidence from cross-age comparisons in eye-tracking and ERP data
Eye-tracking was used to examine how younger and older adults use syntactic and semantic information to disambiguate noun/verb (NV) homographs (e.g., park). We find that young adults exhibit inflated first fixations to NV-homographs when only syntactic cues are available for disambiguation (i.e., …

Word sense disambiguation in clinical text
Lexical ambiguity, the ambiguity arising from a string with multiple meanings, is pervasive in language of all domains. Word sense disambiguation (WSD) and word sense induction (WSI) are the tasks of resolving this ambiguity. Applications in the clinical and biomedical domain focus on the potential …

Disambiguating Biased Ambiguous Words: An Eye Movement Investigation
… results invite us to extend the study of ambiguity resolution beyond the study of the earliest moments of meaning access to include mechanisms such as monitoring, regulation and reanalysis strategies, in meaning integration. That is, in everyday reading tasks, readers face text integration …

Using linguistic knowledge in statistical machine translation
… source side is incorporated, which helps reduce lexical ambiguity. Two methods are proposed for using binary decision trees to control the amount of context information introduced. These methods are successfully applied to the use of diacritized Arabic source in Arabic-to-English translation. The …

Pronunciation modeling for large vocabulary speech recognition
… between pronunciation perplexity and the lexical ambiguity, which has informed the design of the explicit pronunciation models presented here.

Dealing with linguistic mismatches for automatic speech recognition
… mismatches in terms of the number of phonemes, lexical ambiguity, and power of phonotactic constraints provided by phone-level n-grams. In order to address the issues of linguistic mismatches for current ASR systems, my dissertation investigates both knowledge-gnostic and knowledge-agnostic …

"""Paper Has Been My Ruin"": On the Organization of Polysemous Senses"
… to be consistent with a feature-overlap model of lexical ambiguity (Kawamoto, 1993) and with extensional approaches to categorization (Lakoff, 1987; Malt, Sloman, Gennari, Shi & Wang, 1999). A greater understanding of how the different senses of polysemous words are connected and what information …

A morphological-syntactical analysis approach for Arabic textual tagging
… information to words which helps with resolving ambiguity in the meaning of words. Furthermore, diacritics ascribe grammatical functions to the words, differentiating the word from other words, and determining the syntactic position of the word in the sentence. 1. Vocalisation (also referred as …

Competing Cues in Ambiguous Speech Comprehension: The Role of Visual Competition and Linguistic Context
… requires listeners to quickly resolve ambiguity, drawing on both context and word-meaning frequency information to correctly comprehend words with multiple meanings. While it is well established that more common meanings are accessed more easily and that strong context supports …

An investigation of how multiple sources of information are integrated during online reading
… readers can use syntactic cues to resolve the ambiguity associated with noun/verb homographs, the downstream consequences of their resolution processes, and how these effects differ in older adults. Will readers be able to use constraining syntactic information to select the context-appropriate …

La representación de la variación contextual mediante definiciones terminológicas flexible
… factor in the construction of the meaning of lexical units (including terms), we assume that terminological definitions can, and should, reflect the effects of context, even though definitions have traditionally been treated as the expression of meaning void of any contextual effect. The main …

Ambigüedad léxica e interpretación. Un enfoque cognitivo. Enunciados retroactivos y enunciados bivalentes
En este trabajo se desarrolla una hipótesis explicativa de las fases y mecanismos mentales involucrados en el proceso interpretativo de aquellos enunciados en los que la presencia de determinados elementos léxicos ambiguos da lugar a situaciones de doble interpretación, enuncidos bivalentes o puns, …
