This book presents several recent advances in natural language semantics and explores the boundaries between syntax and semantics over the last two decades. It is based on some of the most recent theories in logic, such as linear logic and ludics, first created by Jean-Yves Girard, and it also provides some sharp analyses of computational semantical representations, explaining advanced theories in theoretical computer sciences, such as the lambda-mu and Lambek-Grishin calculi which were applied by Philippe de Groote and Michael Moortgat. The author also looks at Aarne Ranta's 'proof as meaning' approach, which was first based on Martin-Loef's Type Theory.Meaning, Logic and Ludics surveys the many solutions which have been proposed for the syntax-semantics interface, taking into account the specifications of linguistic signs (continuous or discontinuous) and the fundamental mechanisms developed by linguists and notable Generativists. This pioneering publication also presents ludics (in a chapter co-authored with Myriam Quatrini), a framework which allows us to characterize meaning as an invariant with regard to interaction between processes. It is an excellent book for advanced students, and academics alike, in the field of computational linguistics.

This volume contains the key contributions to workshops and meetings that were held within the context of the PRELUDE project. PRELUDE, an acronym for "Towards Theoretical Pragmatics based on Ludics and Continuation Theory", ran from November 2006 to November 2009, with funding from the new French National Agency for Research (ANR). The objective of the project was to develop perspectives on Natural Language Semantics and Pragmatics based on recent developments in Logic and Theoretical Computer Science; the articles shed light on the role of Ludics in the study of speech acts, inferential semantics, game-theoretical frameworks, interactive situations in the dynamics of language, the representation of commitments and interaction, programming web applications, as well as the impact of Ludics on the fundamental concepts of computability.

This book constitutes the thoroughly refereed post-proceedings of the Second International Conference on Logical Aspects of Computational Linguistics, LACL '97, held in Nancy, France in September 1997.
The 10 revised full papers presented were carefully selected during two rounds of reviewing. Also included are two comprehensive invited papers. Among the topics covered are type theory, various types of grammars, linear logic, parsing, type-directed natural language processing, proof-theoretic aspects, concatenation logics, and mathematical languages.
