This book was released on 1992-12-08 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of graph grammars is theoretically attractive and well motivated byvarious applications. More than 20 years ago, the concept of graph grammars was introduced by A. Rosenfeld as a formulation of some problems in pattern recognition and image processing, as well as by H.J. Schneider as a method for data type specification. Within graph-grammar theory one maydistinguish the set-theoretical approach, the algebraic approach, and the logical approach. These approaches differ in the method in which graph replacement is described. Specific approaches, node replacement and hyperedge replacement, concern the basic units of a hypergraph, nodes and hyperedges. This monograph is mainly concerned with the hyperedge-replacement approach. Hyperedge-replacement grammars are introduced as a device for generating hypergraph languages including graph languages and string languages. The concept combines a context-free rewriting with a comparatively large generative power. The volume includes a foreword by H. Ehrig.

Download or read book Handbook of Graph Grammars and Computing by Graph Transformation written by Grzegorz Rozenberg and published by World Scientific. This book was released on 1997-01-01 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graph grammars originated in the late 60s, motivated by considerations about pattern recognition and compiler construction. Since then the list of areas which have interacted with the development of graph grammars has grown quite impressively. Besides the aforementioned areas it includes software specification and development, VLSI layout schemes, database design, modeling of concurrent systems, massively parallel computer architectures, logic programming, computer animation, developmental biology, music composition, visual languages, and many others. The area of graph grammars and graph transformations generalizes formal language theory based on strings and the theory of term rewriting based on trees. As a matter of fact within the area of graph grammars, graph transformation is considered a fundamental programming paradigm where computation includes specification, programming, and implementation.

As a matter of fact within the area of graph grammars, graph transformation is considered a fundamental programming paradigm where computation includes specification, programming, and implementation.Over the last 25-odd years graph grammars have developed at a steady pace into a theoretically attractive and well-motivated research field. In particular, they are now based on very solid foundations, which are presented in this volume. Volume 1 of the indispensable Handbook of Graph Grammars and Computing by Graph Transformations includes a state-of-the-art presentation of the foundations of all the basic approaches to rule-based graph specification and transformation: algebraic approach, logic approach, node-based rewriting, (hyper)edge-based rewriting, programmed graph rewriting, and 2-structures. The book has been written in a tutorial/survey style to enhance its usefulness.

Download or read book Mapping Natural Language Sentences to Semantic Graphs written by Xiaochang Peng and published by . This book was released on 2018 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In recent years, there has been growing interest in graph representations of semantics as a deeper understanding of natural language is increasingly important for user applications such as information extraction, question answering and dialogue systems. Previously, algorithms for producing tree-structured syntax representations given natural language text have been studied extensively, while algorithms for producing semantic graphs are less investigated. In this thesis, we focus on exploring new approaches for mapping natural language sentences to semantic graph structures that can be easily generalized to different semantic graph parsing tasks. More specifically, we present different modeling frameworks that take as input a sentence, and produce a semantic graph representation encoding meaning of the sentence as the output. First, we present a neural sequence-to-sequence model for semantic graph parsing, where vertices and edge labels in the target graph structure are predicted directly. We further propose two mathematically sound formalisms for modeling the derivation sequences for constructing semantic graph structures. In the first approach, we use a graph grammar called Synchronous Hyperedge Replacement Grammar (SHRG) to construct the sentence, graph pairs. We also propose a general transition framework called cache transition system for parsing to graph structures, where a cache with fixed size m is included to analyze different semantic graphs. We evaluate these approaches on a semantic graph representation called Abstract Meaning Representation (AMR), while these approaches are general to extend to other semantic graph representations."--Page x.
