This book is the first to survey current developments in computational phonology, and it does so in a way that is accessible to computational linguists, phonologists and computer scientists alike.

This dissertation provides a coherent, synchronic, broad-coverage, generative phonology of Russian. I test the grammar empirically in a number of ways to determine its goodness of fit to Russian. In taking this approach, I aim to avoid making untested (or even incoherent) generalizations based on only a handful of examples. In most cases, the tests show that there are exceptions to the theory, but at least we know what the exceptions are, a baseline is set against which future theories can be measured, and in most cases the percentage of exceptional cases is reduced to below 5%. The principal theoretical outcomes of the work are as follows. First, I show that all of the phonological or morphophonological processes reviewed can be described by a grammar no more powerful than context-free. Secondly, I exploit probabilistic constraints in the syllable structure grammar to explain why constraints on word-marginal onsets and codas are weaker than on word-internal onsets and codas. I argue that the features []/- initial] and []/- final], and extraprosodicity, are unnecessary for this purpose.

Ruslan Mitkov's highly successful Oxford Handbook of Computational Linguistics has been substantially revised and expanded in this second edition. Alongside updated accounts of the topics covered in the first edition, it includes 17 new chapters on subjects such as semantic role-labelling, text-to-speech synthesis, translation technology, opinion mining and sentiment analysis, and the application of Natural Language Processing in educational and biomedical contexts, among many others. The volume is divided into four parts that examine, respectively: the linguistic fundamentals of computational linguistics; the methods and resources used, such as statistical modelling, machine learning, and corpus annotation; key language processing tasks including text segmentation, anaphora resolution, and speech recognition; and the major applications of Natural Language Processing, from machine translation to author profiling. The book will be an essential reference for researchers and students in computational linguistics and Natural Language Processing, as well as those working in related industries.

This handbook of computational linguistics, written for academics, graduate students and researchers, provides a state-of-the-art reference to one of the most active and productive fields in linguistics.

The International Encyclopedia of Linguistics, 2nd Edition encompasses the full range of the contemporary field of linguistics, including historical, comparative, formal, mathematical, functional, and philosophical linguistics with special attention given to interrelations within branches of linguistics and to relations of linguistics with other disciplines. Areas of intersection with the social and behavioral sciences--ethnolinguistics, sociolinguistics, psycholinguistics, and behavioral linguistics--receive major coverage, along with interdisciplinary work in language and literature, mathematical linguistics, computational linguistics, and applied linguistics.Longer entries in the International Encyclopedia of Linguistics, ranging up to four thousand words, survey the major fields of study--for example, anthropological linguistics, history of linguistics, semantics, and phonetics. Shorter entries treat specific topics within these fields, such as code switching, sound symbolism, and syntactic features. Other short entries define and discuss technical terms used within the various subfields or provide sketches of the careers of important scholars in the history of linguistics, such as Leonard Bloomfield, Roman Jakobson, and Edward Sapir.A major portion of the work is its extensive coverage of languages and language families. From those as familiar as English, Japanese, and the Romance languages to Hittite, Yoruba, and Nahuatl, all corners of the world receive treatment. Languages that are the subject of independent entries are analyzed in terms of their phonology, grammatical features, syntax, and writing systems. Lists attached to each article on a language group or family enumerate all languages, extinct or still spoken, within that group and provide detailed information on the number of known speakers, geographical range, and degree of intelligibility with other languages in the group. In this way, virtually every known language receives coverage.For ease of reference and to aid research, the articles are alphabetically arranged, each signed by the contributor, supported by up-to-date bibliographies, line drawings, maps, tables, and diagrams, and readily accessible via a system of cross-references and a detailed index and synoptic outline. Authoritative, comprehensive, and innovative, the 2nd edition of the International Encyclopedia of Linguistics will be an indispensable addition to personal, public, academic, and research libraries and will introduce a new generation of readers to the complexities and concerns of this field of study.

This book is a revised version of my doctoral thesis which was submitted in April 1993. The main extension is a chapter on evaluation of the system de scribed in Chapter 8 as this is clearly an issue which was not treated in the original version. This required the collection of data, the development of a concept for diagnostic evaluation of linguistic word recognition systems and, of course, the actual evaluation of the system itself. The revisions made primarily concern the presentation of the latest version of the SILPA system described in an additional Subsection 8. 3, the development environment for SILPA in Sec tion 8. 4, the diagnostic evaluation of the system as an additional Chapter 9. Some updates are included in the discussion of phonology and computation in Chapter 2 and finite state techniques in computational phonology in Chapter 3. The thesis was designed primarily as a contribution to the area of compu tational phonology. However, it addresses issues which are relevant within the disciplines of general linguistics, computational linguistics and, in particular, speech technology, in providing a detailed declarative, computationally inter preted linguistic model for application in spoken language processing. Time Map Phonology is a novel, constraint-based approach based on a two-stage temporal interpretation of phonological categories as events.

This volume is the first to provide an up-to-date and comprehensive history of phonology from the earliest known examples of phonological thinking, through the rise of phonology as a field in the twentieth century, and up to the most recent advances. The volume is divided into five parts. Part I offers an account of writing systems along with chapters exploring the great ancient and medieval intellectual traditions of phonological thought that form the foundation of later thinking and continue to enrich phonological theory. Chapters in Part II describe the important schools and individuals of the late nineteenth and early twentieth centuries who shaped phonology as an organized scientific field. Part III examines mid-twentieth century developments in phonology in the Soviet Union, Northern and Western Europe, and North America; it continues with precursors to generative grammar, and culminates in a chapter on Chomsky and Halle's The Sound Pattern of English (SPE). Part IV then shows how phonological theorists responded to SPE with respect to derivations, representations, and phonology-morphology interaction. Theories discussed include Dependency Phonology, Government Phonology, Constraint-and-Repair theories, and Optimality Theory. The part ends with a chapter on the study of variation. Finally, chapters in Part V look at new methods and approaches, covering phonetic explanation, corpora and phonological analysis, probabilistic phonology, computational modelling, models of phonological learning, and the evolution of phonology. This in-depth exploration of the history of phonology provides new perspectives on where phonology has been and sheds light on where it could go next.

By the late 1970s phonologists, and later morphologists, had departed from a linear approach for describing morphophonological operations to a nonlinear one. Computational models, however, remain faithful to the linear model, making it very difficult, if not impossible, to implement the morphology of languages whose morphology is nonconcatanative. Computational Nonlinear Morphology aims at presenting a computational system that counters the development in linguistics. It provides a detailed computational analysis of the complex morphophonological phenomena found in Semitic languages based on linguistically motivated models.

Previous work on morphology has largely tended either to avoid precise computational details or to ignore linguistic generality. Computational Morphologyis the first book to present an integrated set of techniques for the rigorous description of morphological phenomena in English and similar languages. By taking account of all facets of morphological analysis, it provides a linguistically general and computationally practical dictionary system for use within an English parsing program. The authors covermorphographemics (variations in spelling as words are built from their component morphemes),morphotactics (the ways that different classes of morphemes can combine, and the types of words that result), andlexical redundancy (patterns of similarity and regularity among the lexical entries for words). They propose a precise rule-notation for each of these areas of linguistic description and present the algorithms for using these rules computationally to manipulate dictionary information. These mechanisms have been implemented in practical and publicly available software, which is described in detail, and appendixes contain a large number of computer-tested sets of rules and lexical entries for English.
