Ambiguity Resolution in Language Learning

Lexical Ambiguity Resolution

The most frequently used words in English are highly ambiguous; for example, Webster's Ninth New Collegiate Dictionary lists 94 meanings for the word "run" as a verb alone. Yet people rarely notice this ambiguity. Solving this puzzle has commanded the efforts of cognitive scientists for many years. The solution most often identified is "context": we use the context of utterance to determine the proper meanings of words and sentences. The problem then becomes specifying the nature of context and how it interacts with the rest of an understanding system. The difficulty becomes especially apparent in the attempt to write a computer program to understand natural language. Lexical ambiguity resolution (LAR), then, is one of the central problems in natural language and computational semantics research. A collection of the best research on LAR available, this volume offers eighteen original papers by leading scientists. Part I, Computer Models, describes nine attempts to discover the processes necessary for disambiguation by implementing programs to do the job. Part II, Empirical Studies, goes into the laboratory setting to examine the nature of the human disambiguation mechanism and the structure of ambiguity itself. A primary goal of this volume is to propose a cognitive science perspective arising out of the conjunction of work and approaches from neuropsychology, psycholinguistics, and artificial intelligence--thereby encouraging a closer cooperation and collaboration among these fields. Lexical Ambiguity Resolution is a valuable and accessible source book for students and cognitive scientists in AI, psycholinguistics, neuropsychology, or theoretical linguistics.

Bilingual Lexical Ambiguity Resolution

This book provides students and researchers of bilingualism with the most recent methodological and theoretical advances on how bilinguals resolve ambiguous information across languages. With reports on the latest findings from the behavioral and neuropsychological fields, the authors survey the latest research into bilingual language-system modelling and bilingual lexical ambiguity processing. Each chapter looks at bilingual ambiguity resolution both at the word and sentence levels, explaining how bilinguals ultimately comprehend ambiguous information arising from languages they already know. This volume not only explores enduring theoretical questions in bilingual research, such as bilingual representation and language processing, but also evaluates the extent to which the existing bilingual models can satisfactorily account for the most recent research findings.
