A modern information retrieval system must have the capability to find, organize and present very different manifestations of information – such as text, pictures, videos or database records – any of which may be of relevance to the user. However, the concept of relevance, while seemingly intuitive, is actually hard to define, and it's even harder to model in a formal way. Lavrenko does not attempt to bring forth a new definition of relevance, nor provide arguments as to why any particular definition might be theoretically superior or more complete. Instead, he takes a widely accepted, albeit somewhat conservative definition, makes several assumptions, and from them develops a new probabilistic model that explicitly captures that notion of relevance. With this book, he makes two major contributions to the field of information retrieval: first, a new way to look at topical relevance, complementing the two dominant models, i.e., the classical probabilistic model and the language modeling approach, and which explicitly combines documents, queries, and relevance in a single formalism; second, a new method for modeling exchangeable sequences of discrete random variables which does not make any structural assumptions about the data and which can also handle rare events. Thus his book is of major interest to researchers and graduate students in information retrieval who specialize in relevance modeling, ranking algorithms, and language modeling.

The present volume covers a variety of topics which are at the centre of interest in pragmatic research: understanding and believing, reference, politeness, communication problems, stylistics, metaphor, and humour. Next to innovative theoretical proposals, there are interesting analyses and discussions.

This volume is one of the first books to present a comprehensive view of lexical pragmatics, describing its origins, assumptions, scope, methodology and the various approaches to it, focusing specifically on the approach offered by relevance theory. In addition to theoretical considerations, the book discusses particular linguistic expressions and pragmatic phenomena, showing how the relevance-theoretic tools may be used to explore pragmatically motivated changes to lexically encoded meanings. The most recent developments are discussed and questions are asked to indicate directions for further research within this rapidly developing field.

The Handbook of Pragmatics is a collection of newly commissioned articles that provide an authoritative and accessible introduction to the field, including an overview of the foundations of pragmatic theory and a detailed examination of the rich and varied theoretical and empirical subdomains of pragmatics. Contains 32 newly commissioned articles that outline the central themes and challenges for current research in the field of linguistic pragmatics. Provides authoritative and accessible introduction to the field and a detailed examination of the varied theoretical and empirical subdomains of pragmatics. Includes extensive bibliography that serves as a research tool for those working in pragmatics and allied fields in linguistics, philosophy, and cognitive science. Valuable resource for both students and professional researchers investigating the properties of meaning, reference, and context in natural language.

This book represents a substantial contribution to the field of linguistics in drawing together the author's most significant work on the theory of generative grammar.

This book provides a critical review of the development of generative grammar, both transformational and non-transformational, from the early 1960s to the present, and presents contemporary results in the context of an overall evaluation of recent research in the field. Geoffrey Horrocks compares Chomsky's approach to the study of grammar, culminating in Government and Binding theory, with two other theories which are deliberate reactions to this framework: Generalised Phrase Structure Grammar and Lexical-Functional Grammar. Whilst proponents of all three models regard themselves as generative grammarians, and share many of the same objectives, the differences between them nevertheless account for much of the recent debate in this subject. By presenting these different theories in the context of the issues that unite and divide them, the book highlights the problems which arise in any attempt to establish an adequate theory of grammatical representation.

An authoritative general introduction to cognitive linguistics, this book provides up-to-date coverage of all areas of the field and sets in context recent developments within cognitive semantics (including primary metaphors, conceptual blending and Principled Polysemy), and cognitive approaches to grammar (including Radical Construction Grammar and Embodied Construction Grammar). While all topics are introduced in terms accessible to both undergraduate and postgraduate students, this work is sufficiently comprehensive and detailed to serve as a reference work for scholars from linguistics and neighbouring disciplines who wish to gain a better understanding of cognitive linguistics. The book is divided into three parts (The cognitive linguistics enterprise; Cognitive semantics; and Cognitive approaches to grammar), and is therefore suitable for a range of different course types, both in terms of length and level, as well as in terms of focus. In addition to defining the field, the text also includes appropriate critical evaluation. Complementary and potentially competing approaches are explored both within the cognitive approach and beyond it. In particular, cognitive linguistics is compared and contrasted with formal approaches including Generative Grammar, formal approaches to semantics, and Relevance Theory.Features:*Exercises at the end of each chapter*Annotated reading list at the end of each chapter*Lively and accessible presentation *Full bibliography*Contains 200 diagrammatic illustrations
