This volume presents the latest research in linguistic modules and interfaces in Lexical-Functional Grammar (LFG). LFG has a highly modular design that models the linguistic system as a set of discreet submodules that include, among others, constituent structure, functional structure, argument structure, semantic structure, and prosodic structure; each module has its own coherent properties and is related to other modules by correspondence functions. Following a detailed introduction, Part I examines the nature of linguistic structures, interfaces, and representations in LFG's architecture and ontology. Parts II and III are concerned with problems, analyses, and generalizations associated with linguistic phenomena of long-standing theoretical significance, including agreement, reciprocals, possessives, reflexives, raising, subjecthood, and relativization, demonstrating how these phenomena can be naturally accounted for within LFG's modular architecture. Part IV explores issues of the synchronic and diachronic dynamics of syntactic categories in grammar, such as unlike category coordination, fuzzy categorial edges, and consequences of decategorialization, providing explicit LFG solutions to such problems, including those resulting from language change in progress. The final part re-examines and refines the precise representations and interfaces of syntax with morphology, semantics, and pragmatics to account for challenging facts such as suspended affixation, prosody in multiple question word interrogatives and information structure, anaphoric dependencies, and idioms. The volume draws on data from a range of typologically diverse languages, including Arabic, Chinese, Icelandic, Kelabit, Polish, and Urdu, and will be of interest not only to those working in LFG and related frameworks, but to all those working on linguistic interfaces from a variety of theoretical standpoints.

Modular grammar postulates several autonomous generative systems interacting with one another as opposed to the prevailing theory of transformational grammar where there is a single generative component – the syntax – from which other representations are derived. In this book Jerrold Sadock develops his influential theory of grammar, formalizing several generative modules that independently characterize the levels of syntax, semantics, role structure, morphology and linear order, as well as an interface system that connects them. Multi-modular grammar provides simpler, more intuitive analyses of grammatical phenomena and allows for greater empirical coverage than prevailing styles of grammar. The book illustrates this with a wide-ranging analysis of English grammatical phenomena, including raising, control, passive, inversion, do-support, auxiliary verbs and ellipsis. The modules are simple enough to be cast as phrase structure grammars and are presented in sufficient detail to make descriptions of grammatical phenomena more explicit than the approximate accounts offered in other studies.

Lexical Functional Grammar (LFG) is a nontransformational theory of linguistic structure, first developed in the 1970s by Joan Bresnan and Ronald M. Kaplan, which assumes that language is best described and modeled by parallel structures representing different facets of linguistic organization and information, related by means of functional correspondences. This volume has five parts. Part I, Overview and Introduction, provides an introduction to core syntactic concepts and representations. Part II, Grammatical Phenomena, reviews LFG work on a range of grammatical phenomena or constructions. Part III, Grammatical modules and interfaces, provides an overview of LFG work on semantics, argument structure, prosody, information structure, and morphology. Part IV, Linguistic disciplines, reviews LFG work in the disciplines of historical linguistics, learnability, psycholinguistics, and second language learning. Part V, Formal and computational issues and applications, provides an overview of computational and formal properties of the theory, implementations, and computational work on parsing, translation, grammar induction, and treebanks. Part VI, Language families and regions, reviews LFG work on languages spoken in particular geographical areas or in particular language families. The final section, Comparing LFG with other linguistic theories, discusses LFG work in relation to other theoretical approaches.

This book highlights recent advances in the design of hybrid intelligent systems based on nature-inspired optimization and their application in areas such as intelligent control and robotics, pattern recognition, time series prediction, and optimization of complex problems. The book is divided into seven main parts, the first of which addresses theoretical aspects of and new concepts and algorithms based on type-2 and intuitionistic fuzzy logic systems. The second part focuses on neural network theory, and explores the applications of neural networks in diverse areas, such as time series prediction and pattern recognition. The book’s third part presents enhancements to meta-heuristics based on fuzzy logic techniques and describes new nature-inspired optimization algorithms that employ fuzzy dynamic adaptation of parameters, while the fourth part presents diverse applications of nature-inspired optimization algorithms. In turn, the fifth part investigates applications of fuzzy logic in diverse areas, such as time series prediction and pattern recognition. The sixth part examines new optimization algorithms and their applications. Lastly, the seventh part is dedicated to the design and application of different hybrid intelligent systems.

Reversible grammar allows computational models to be built that are equally well suited for the analysis and generation of natural language utterances. This task can be viewed from very different perspectives by theoretical and computational linguists, and computer scientists. The papers in this volume present a broad range of approaches to reversible, bi-directional, and non-directional grammar systems that have emerged in recent years. This is also the first collection entirely devoted to the problems of reversibility in natural language processing. Most papers collected in this volume are derived from presentations at a workshop held at the University of California at Berkeley in the summer of 1991 organised under the auspices of the Association for Computational Linguistics. This book will be a valuable reference to researchers in linguistics and computer science with interests in computational linguistics, natural language processing, and machine translation, as well as in practical aspects of computability.
