Studies In Syntactic 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.

One of the liveliest forums for sharing psychological, linguistic, philosophical, and computer science perspectives on psycholinguistics has been the annual meeting of the CUNY Sentence Processing Conference. Documenting the state of the art in several important approaches to sentence processing, this volume consists of selected papers that had been presented at the Sixth CUNY Conference. The editors not only present the main themes that ran through the conference but also honor the breadth of the presentations from disciplines including linguistics, experimental psychology, and computer science. The variety of sentence processing topics examined includes: * how evoked brain potentials reflect sentence comprehension * how auditory words are processed * how various sources of grammatical and nongrammatical information are coordinated and used * how sentence processing and language acquisition might be related. This distinctive volume not only presents the most exciting current work in sentence processing, but also places this research into the broader context of theorizing about it.

The authors present a comprehensive overview of past research in ambiguity in the field of psycholinguistics. Experimental results have often been equivocal in allowing a choice between the single-reading hypothesis and the multiple-reading hypothesis of processing of ambiguous sentences. This text reviews the arguments and experimental results in support of each of these views, and further investigates the contributions of context and thematic constraints in the process of ambiguity resolution. Commentary is also made on the possible hierarchical ordering of difficulty in the treatment of ambiguity, as well as critically related considerations like bias, individual differences, general cognitive strategies for dealing with multiphase representations, and the inherent differences between lexical and syntactic ambiguity.

This volume features the complete text of all regular papers, posters, and summaries of symposia presented at the 15th annual meeting of the Cognitive Science Society.

Semantic interpretation and the resolution of ambiguity presents an important advance in computer understanding of natural language. While parsing techniques have been greatly improved in recent years, the approach to semantics has generally improved in recent years, the approach to semantics has generally been ad hoc and had little theoretical basis. Graeme Hirst offers a new, theoretically motivated foundation for conceptual analysis by computer, and shows how this framework facilitates the resolution of lexical and syntactic ambiguities. His approach is interdisciplinary, drawing on research in computational linguistics, artificial intelligence, montague semantics, and cognitive psychology.

Seminar paper from the year 2006 in the subject English Language and Literature Studies - Linguistics, grade: 1, University of Marburg (Fremdsprachliche Philologien), course: Proseminar Semantics, language: English, abstract: "Ambiguity is pervasive at all levels of analysis. It has been, is, and is likely to remain the key problem in natural language processing." (Gadzar 1993:161) This statement by Gerald Gadzar expresses the necessity to cope with the challenge of ambiguity resolution. As the phenomenon of ambiguity is widespread in human language, an interesting question would be: How could a machine be able to handle ambiguity while even humans have difficulties in solving such problems? This paper will first define the phenomenon of ambiguity and explain the different types of it. An interesting aspect will be the effect of garden path sentences.

There are between 4,000 and 6,000 languages remaining in the world and the characteristics of these languages vary widely. How could an infant born today master any language in the world, regardless of the language’s characteristics? Shelia M. Kennison answers this question through a comprehensive introduction to language development, taking a unique perspective that spans the period before birth through old age. Introduction to Language Development offers in-depth discussions on key topics, including: the biological basis of language, perceptual development, grammatical development, development of lexical knowledge, social aspects of language, bilingualism, the effect of language on thought, cognitive processing in language production and comprehension, language-related delays and disorders, and language late in life.
