Download or read book Scattered Context Grammars and Their Applications written by Alexander Meduna and published by WIT Press. This book was released on 2010 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This computer science book represents scattered information by formal languages and gives an in-depth discussion of scattered context grammars as formal means that process these languages. It is primarily meant as a monograph on these grammars, which represent an important trend of todays formal language theory. The text maintains a balance between fundamental concepts, theoretical results, and applications of these grammars. From a theoretical viewpoint, it introduces several variants of scattered context grammatical models. Based on these models, it demonstrates the concepts, methods, and techniques employed in handling scattered pieces of information with enough rigors to make them quite clear. It also explains a close relation between the subject of the book and several important mathematical fields, such as algebra and graph theory. From a more practical point of view, this book describes scattered information processing by fundamental information technologies. Throughout this book, several in-depth case studies and examples are carefully presented. Whilst discussing various methods concerning grammatical processing of scattered information, the text illustrates their applications with a focus on applications in linguistics.

Book excerpt: Scattered context grammars can be regarded as web grammars in which the web is the transitive closure of string. It is an open question whether such grammars are strictly weaker than context-sensitive grammars. The report shows that if 'negative context' is allowed, they are as strong as context-sensitive grammars. Negative context alone appears to be comparable in power to (positive) scattered context, but it has not yet been shown that negative context grammars are strictly weaker than context-sensitive grammars. Unordered (positive or negative) scattered context is apparently even weaker, though still stronger than context-free; in web grammar terms, it corresponds to using the complete (undirected) web.

Download or read book Jumping Computation written by Alexander Meduna and published by CRC Press. This book was released on 2024-03-07 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jumping Computation: Updating Automata and Grammars for Discontinuous Information Processing is primarily a theoretically oriented treatment of jumping automata and grammars, covering all essential theoretical topics concerning them, including their power, properties, and transformations. From a practical viewpoint, it describes various concepts, methods, algorithms, techniques, case studies and applications based upon these automata and grammars. In today’s computerized world, the scientific development and study of computation, referred to as the theory of computation, plays a crucial role. One important branch, language theory, investigates how to define and study languages and their models, which formalize algorithms according to which their computation is executed. These language-defining models are classified into two basic categories: automata, which define languages by recognizing their words, and grammars, which generate them. Introduced many decades ago, these rules reflect classical sequential computation. However, today’s computational methods frequently process information in a fundamentally different way, frequently “jumping” over large portions of the information as a whole. This book adapts classical models to formalize and study this kind of computation properly. Simply put, during their language-defining process, these adapted versions, called jumping automata and grammars, jump across the words they work on. The book selects important models and summarizes key results about them in a compact and uniform way. It relates each model to a particular form of modern computation, such as sequential, semi-parallel and totally parallel computation, and explains how the model in question properly reflects and formalizes the corresponding form of computation, thus allowing us to obtain a systematized body of mathematically precise knowledge concerning the jumping computation. The book pays a special attention to power, closure properties, and transformations, and also describes many algorithms that modify jumping grammars and automata so they satisfy some prescribed properties without changing the defined language. The book will be of great interest to anyone researching the theory of computation across the fields of computer science, mathematics, engineering, logic and linguistics.

Download or read book Handbook of Formal Languages written by Grzegorz Rozenberg and published by Springer Science & Business Media. This book was released on 1997-02-28 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for a comprehensive survey-type exposition on formal languages and related mainstream areas of computer science has been evident for some years. In the early 1970s, when the book Formal Languages by the second mentioned editor appeared, it was still quite feasible to write a comprehensive book with that title and include also topics of current research interest. This would not be possible anymore. A standard-sized book on formal languages would either have to stay on a fairly low level or else be specialized and restricted to some narrow sector of the field. The setup becomes drastically different in a collection of contributions, where the best authorities in the world join forces, each of them concentrat ing on their own areas of specialization. The present three-volume Handbook constitutes such a unique collection. In these three volumes we present the current state of the art in formallanguage theory. We were most satisfied with the enthusiastic response given to our request for contributions by specialists representing various subfields. The need for a Handbook of Formal Languages was in many answers expressed in different ways: as an easily accessible his torical reference, a general source of information, an overall course-aid, and a compact collection of material for self-study. We are convinced that the final result will satisfy such various needs.

Available in PDF, EPUB and Kindle. Book excerpt: Containing contributions from both theoretical computer scientists and people working in areas where multi-agent architectures are involved (artificial intelligence, artificial life, linguistics, managing complex systems), this book presents both theoretical developments and applications of grammar systems of various types (cooperating distributed grammar systems, eco-grammar). A survey of notions and results in grammar system theory is included. This book, the first one of its type, is of interest to researchers faced with complex systems which can be approached at a "syntactic" level (as symbol manipulating systems), as a distributed structure, as well as for computer scientists and mathematicians interested in grammar systems theory, who can find here both basic references, recent developments and suggestions for further research and applications.
