Computing of Graphs of Relations Using Generative Grammars

چکیده

— By considering représentations of graphs of relations on the set of natural numbers by bounded languages it is possible to develop a study of relations which are computable in a certain sensé by context-sensitive grammars. There are obtained closure proprieties for the class of these relations, which allow to prove the context-sensitiveness of certain languages. Résumé. — En représentant les graphes de relations définies sur les nombres entiers par des langages bornés, on peut étudier les relations qui sont calculables (en un certain sens) par des grammaires « context-sensitive ». On obtient des propriétés de fermeture pour cette famille de relations, qui permettent d'établir que certains langages sont « context-sensitive ».

Practical Applications of Precedence Graph Grammars

Precedence graph grammars are of major interest in all those applications of graph grammars, where highly efficient parsers are needed. Up to now there are no other graph parsers with the same performance. Due to the fact, that even regular graph grammars with very restricted embedding relations have a NP-complete membership problem, different kinds than Chomsky-like restrictions have to be imp...

Just chromatic exellence in fuzzy graphs

A fuzzy graph is a symmetric binary fuzzy relation on a fuzzy subset. The concept of fuzzy sets and fuzzy relations was introduced by L.A.Zadeh in 1965cite{zl} and further studiedcite{ka}. It was Rosenfeldcite{ra} who considered fuzzy relations on fuzzy sets and developed the theory of fuzzy graphs in 1975. The concepts of fuzzy trees, blocks, bridges and cut nodes in fuzzy graph has been studi...

Alternating Regular Tree Grammars in the Framework of Lattice-Valued Logic

In this paper, two different ways of introducing alternation for lattice-valued (referred to as {L}valued)  regular tree grammars and {L}valued top-down tree automata are compared. One is the way which defines the alternating regular tree grammar, i.e., alternation is governed by the non-terminals of the grammar and the other is the way which combines state with alternation. The first way is ta...

Modeling Graph Languages with Grammars Extracted via Tree Decompositions

Work on probabilistic models of natural language tends to focus on strings and trees, but there is increasing interest in more general graph-shaped structures since they seem to be better suited for representing natural language semantics, ontologies, or other varieties of knowledge structures. However, while there are relatively simple approaches to defining generative models over strings and ...

The Power of Programmed Grammars with Graphs from Various Classes

Programmed grammars, one of the most important and well investigated classes of grammars with context-free rules and a mechanism controlling the application of the rules, can be described by graphs. We investigate whether or not the restriction to special classes of graphs restricts the generative power of programmed grammars with erasing rules and without appearance checking, too. We obtain th...
