In spite of the rapid growth of interest in the computer analysis of language, this book provides an integrated introduction to the field. Inevitably, when many different approaches are still being considered, a straightforward work of synthesis would be neither possible nor practicable. Nevertheless, Ralph Grishman provides a valuable survey of various approaches to the problems of syntax analysis, semantic analysis, text analysis and natural language generation, while considering in greater detail those that seem to him most productive. The book is written for readers with some background...

This book deals with a major problem in the study of language: the problem of reference. The ease with which we refer to things in conversation is deceptive. Upon closer scrutiny, it turns out that we hardly ever tell each other explicitly what object we mean, although we expect our interlocutor to discern it. Amichai Kronfeld provides an answer to two questions associated with this: how do we successfully refer, and how can a computer be programmed to achieve this? Beginning with the major theories of reference, Dr Kronfeld provides a consistent philosophical view which is a synthesis of...

This book explores the tradition of the "science of man" in French medicine of the era 1750-1850, focusing on controversies about the nature of the "physical-moral" relation and their effects on the role of medicine in French society. Its chief purpose is to recover the history of a holistic tradition in French medicine that has been neglected, because it lay outside the mainstream themes of modern medicine, which include experimental, reductionist, and localistic conceptions of health and disease. Professor Williams also challenges existing historiography, which holds that the...

This book presents a collection of papers on the issue of focus in its broadest sense. While commonly considered as being related to phenomena such as presupposition and anaphora, focusing is much more widely spread, and it is this pervasiveness that the current collection addresses. The work loosely originates from a conference held in 1994 in Schloss Wolfsbrunnen in Germany, although only a small subpart of the proceedings papers presented are included here. The contributed papers have been reworked for the current volume to present a coherent study of the subject.

This book explains how to build Natural Language Generation (NLG) systems--computer software systems that automatically generate understandable texts in English or other human languages. NLG systems use knowledge about language and the application domain to automatically produce documents, reports, explanations, help messages, and other kinds of texts. The book covers the algorithms and representations needed to perform the core tasks of document planning, microplanning, and surface realization, using a case study to show how these components fit together. It is essential reading for...

People often mean more than they say. Grammar on its own is typically insufficient for determining the full meaning of an utterance; the assumption that the discourse is coherent or ?makes sense? has an important role to play in determining meaning as well. Logics of Conversation presents a dynamic semantic framework called Segmented Discourse Representation Theory, or SDRT, where this interaction between discourse coherence and discourse interpretation is explored in a logically precise manner. Combining ideas from dynamic semantics, commonsense reasoning and speech act theory, SDRT uses its...

This innovative book develops a formal computational theory of writing systems and relates it to psycholinguistic results. Drawing on case studies of writing systems around the world, it offers specific proposals about the linguistic objects that are represented by orthographic elements and the formal constraints that hold of the mapping relation between them. Based on the insights gained, it posits a new taxonomy of writing systems. The book will be of interest to students and researchers in theoretical and computational linguistics, the psycholinguistics of reading and writing, and speech...

This original volume describes the Spoken Language Translator (SLT), one of the first major automatic speech translation projects. The SLT system can translate between English, French, and Swedish in the domain of air travel planning, using a vocabulary of about 1500 words, and with an accuracy of about 75%. The authors detail the language processing components, largely built on top of the SRI Core Language Engine, using a combination of general grammars and techniques that allow them to be rapidly customized to specific domains. They base speech recognition on Hidden Markov Mode technology,...

A primary problem in the area of natural language processing has been semantic analysis. This book looks at the semantics of natural languages in context. It presents an approach to the computational processing of English text that combines current theories of knowledge representation and reasoning in Artificial Intelligence with the latest linguistic views of lexical semantics. The book will interest postgraduates and researchers in computational linguistics as well as industrial research groups specializing in natural language processing.

Inheritance has been used in AI knowledge representation for many years. Until recently, however, it had not been much exploited in linguistic representation. This collection describes how the lexicon may be structured using inheritance. The papers are mostly formal in orientation, mainly concentrating on unification-based systems (which nowadays form the basis for most theoretically motivated work on NLP, and for current linguistic theories such as HPSG) and discuss syntax and morphology as well as lexical semantics. The formalization of default inheritance, in particular, is discussed in...
