The central task of future-oriented computational linguistics is the development of cognitive machines which humans can freely speak to in their natural language. This will involve the development of a functional theory of language, an objective method of verification, and a wide range of practical applications. Natural communication requires not only verbal processing, but also non-verbal perception and action. Therefore, the content of this book is organized as a theory of language for the construction of talking robots with a focus on the mechanics of natural language communication in both the listener and the speaker.
Statistical approaches to processing natural language text have become dominant in recent years. This foundational text is the first comprehensive introduction to statistical natural language processing (NLP) to appear. The book contains all the theory and algorithms needed for building NLP tools. It provides broad but rigorous coverage of mathematical and linguistic foundations, as well as detailed discussion of statistical methods, allowing students and researchers to construct their own implementations. The book covers collocation finding, word sense disambiguation, probabilistic parsing, information retrieval, and other applications.

The central task of a future-oriented computational linguistics is the development of cognitive machines which humans can freely talk with in their respective natural language. In the long run, this task will ensure the development of a functional theory of language, an objective method of verification, and a wide range of practical applications. Natural communication requires not only verbal processing, but also non-verbal perception and action. Therefore the content of this textbook is organized as a theory of language for the construction of talking robots. The main topic is the mechanism of natural language communication in both the speaker and the hearer. The content is divided into four parts: Theory of Language, Theory of Grammar, Morphology and Syntax, Semantics and Pragmatics. The book contains more than 700 exercises for reviewing key ideas and important problems. In the Second Edition, changes are most noticeable in Chapters 22-24, which have been completely rewritten. They present a declarative outline for programming the semantic and pragmatic interpretation of natural language communication. The presentation is now simpler and more comprehensive. It is defined as a formal fragment and includes a new control structure, an analysis of spatio-temporal infer-encing, and an analysis of internal matching based on the notion of a task analysis. Examples and explanations which were contained in the old versions of Chapters 22-24 have been moved to the new Appendix. A schematic summary and a conclusion have been added as well.
As an interdisciplinary field, computational linguistics has its sources in several areas of science, each with its own goals, methods, and historical background. Thereby, it has remained unclear which components fit together and which do not. This suggests three possible approaches to designing a computational linguistics textbook. The first approach proceeds from one's own school of thought, usually determined of study, rather than by a well-informed, delib by chance, such as one's initial place erate choice. The goal is to extend the inherited theoretical framework or method to as many aspects of language analysis as possible. As a consequence, the issue of com pat ibility with other approaches in the field need not be addressed and one's assumptions are questioned at best in connection with 'puzzling problems. ' The second approach takes the viewpoint of an objective observer and aims to survey the field as completely as possible. However, the large number of different schools, methods, and tasks necessitates a subjective selection. Furthermore, the pre sumed neutrality provides no incentive to investigate the compatibility between the elements selected. The third approach aims at solving a comprehensive functional task, with the differ To arrive at the desired solution, suitability ent approaches being ordered relative to it. and compatibility of the different elements adopted must be investigated with regard to the task at hand.
This book provides a systematic study of three foundational issues in the semantics of natural language that have been relatively neglected in the past few decades. focuses on the formal characterization of intensions, the nature of an adequate type system for natural language semantics, and the formal power of the semantic representation language proposes a theory that offers a promising framework for developing a computational semantic system sufficiently expressive to capture the properties of natural language meaning while remaining computationally tractable written by two leading researchers and of interest to students and researchers in formal semantics, computational linguistics, logic, artificial intelligence, and the philosophy of language
In Methods in Latin Computational Linguistics, Barbara McGillivray presents some of the most significant methodological foundations of the emerging field of Latin Computational Linguistics. The reader will find an overview of the computational resources and tools available for Latin and three corpus case studies covering morpho-syntactic and lexical-semantic aspects of Latin verb valency, as well as quantitative diachronic explorations of the argument realization of Latin prefixed verbs. The computational models and the multivariate data analysis techniques employed are explained with a detailed but accessible language. Barbara McGillivray convincingly shows the challenges and opportunities of combining computational methods and historical language data, and contributes to driving the technological change that is affecting Historical Linguistics and the Humanities.
How does human language work? How do we put ideas into words that others can understand? Can linguistics shed light on the way the brain operates? Foundations of Language puts linguistics back at the centre of the search to understand human consciousness. Ray Jackendoff begins by surveying the developments in linguistics over the years since Noam Chomsky's Aspects of the Theory of Syntax. He goes on to propose a radical re-conception of how the brain processes language. This opens up vivid new perspectives on every major aspect of language and communication, including grammar, vocabulary, learning, the origins of human language, and how language relates to the real world. Foundations of Language makes important connections with other disciplines which have been isolated from linguistics for many years. It sets a new agenda for close cooperation between the study of language, mind, the brain, behaviour, and evolution.
The volume presents an up-to-date collection of methodologically sensitive contributions providing mainly enthusiastic, at times also critical support for the cognitive-linguistic enterprise. The book is important for the advancement of cognitive linguistics because the contributions demonstrate the seriousness of its ambitions to develop into a set of testable linguistic approaches. For the same reason, the volume is a contribution to our understanding of language in general, since it puts a promising modern approach on firmer ground. Assets of the book include the wide range of linguistic phenomena studied (individual concepts, fundamental semantic problems like vagueness and polysemy, grammatical issues incl. gender and tense, collocations, constructions and speech acts) and the scope of applied perspectives including lexicographical, computational, developmental and critical discourse ones. The languages investigated are English, German, Dutch, Polish and Italian. Common to the contributions is the desire to bring together observed patterns of linguistic usage with concepts and models established in cognitive linguistics. In addition, all contributions have an empirical basis and emphasize the need to rely on a sound methodology. The linguistic phenomena investigated span the range from the lexico-conceptual and collocational level to constructions, grammatical categories and functions. Two complementary perspectives of language and cognition are represented in the volume: In one group, the established methods of psycholinguistic experimentation, quantitative corpus analysis and computational simulation are exploited to demonstrate the viability and to increase the plausibility of cognitive-linguistic thinking. The second group tests well-known cognitive-linguistic approaches like Conceptual Metaphor Theory, the Theory of Idealized Cognitive Models and Construction Grammar against authentic data demonstrating their applicability and explanatory potential. Both groups include contributions reaching beyond the scope of traditional cognitive-linguistic topics, e.g. by taking a critical stance of reductionist cognitive thinking. The volume is of interest to cognitive linguists, psycholinguists, theoretical linguists, lexicologists, and lexicographers.
This book presents a new paradigm of natural language grammar analysis, based on adposition as the key concept, considered a general connection between two morphemes – or group of morphemes. The adpositional paradigm considers the morpheme as the basic unit to represent morphosyntax, taken as a whole, in terms of constructions, while semantics and pragmatics are treated accordingly. All linguistic observations within the book can be described through the methods and tools of Constructive Mathematics, so that the modelling becomes formally feasible. A full description in category-theoretic terms of the formal model is provided in the Appendix. A lot of examples taken from natural languages belonging to different typological areas are offered throughout the volume, in order to explain and validate the modeling – with special attention given to ergativity. Finally, a first real-world application of the paradigm is given, i.e., conversational analysis of the transcript of therapeutic settings in terms of constructive speech acts. The main goal of this book is to broaden the scope of Linguistics by including Constructive Mathematics in order to deal with known topics such as grammaticalization, children’s speech, language comparison, dependency and valency from a different perspective. It primarily concerns advanced students and researchers in the field of Theoretical and Mathematical Linguistics but the audience can also include scholars interested in applications of Topos Theory in Linguistics.
