Growing Graphs with Hyperedge Replacement Graph Grammars [PDF]

open access: yesProceedings of the 25th ACM International on Conference on Information and Knowledge Management, 2016
Discovering the underlying structures present in large real world graphs is a fundamental scientific problem. In this paper we show that a graph's clique tree can be used to extract a hyperedge replacement grammar.

Compressing graphs by grammars [PDF]

open access: yes2016 IEEE 32nd International Conference on Data Engineering (ICDE), 2016
We present a new graph compressor that detects repeating substructures and represents them by grammar rules. We show that for a large number of graphs the compressor obtains smaller representations than other approaches. For RDF graphs and version graphs it outperforms the best known previous methods.

Towards Translating Graph Transformation Approaches by Model Transformations [PDF]

open access: yes, 2006
Recently, many researchers are working on semantics preserving model transformation. In the field of graph transformation one can think of translating graph grammars written in one approach to a behaviourally equivalent graph grammar in another approach.

Factor Graph Grammars

open access: yesCoRR, 2020
We propose the use of hyperedge replacement graph grammars for factor graphs, or factor graph grammars (FGGs) for short. FGGs generate sets of factor graphs and can describe a more general class of models than plate notation, dynamic graphical models, case-factor diagrams, and sum-product networks can.

Graph Grammars, Insertion Lie Algebras, and Quantum Field Theory [PDF]

open access: yes, 2015
Graph grammars extend the theory of formal languages in order to model distributed parallelism in theoretical computer science. We show here that to certain classes of context-free and context-sensitive graph grammars one can associate a Lie algebra ...

Event-driven grammars: Relating abstract and concrete levels of visual languages [PDF]

open access: yes, 2007
The final publication is available at Springer via http://dx.doi.org/10.1007/s10270-007-0051-2In this work we introduce event-driven grammars, a kind of graph grammars that are especially suited for visual modelling environments generated by meta ...

Probabilistic regular graphs [PDF]

open access: yes, 2010
Deterministic graph grammars generate regular graphs, that form a structural extension of configuration graphs of pushdown systems. In this paper, we study a probabilistic extension of regular graphs obtained by labelling the terminal arcs of the graph ...

Translating Controlled Graph Grammars to Ordinary Graph Grammars

open access: yesElectronic Notes in Theoretical Computer Science, 2016
AbstractGraph Grammar (GG) is an appropriate formal language for specifying complex systems. In a GG the system states are represented by graphs and the changes between the states are described by rules. The use of GGs is interesting as there are several techniques for the specification and verification of systems that are described in this language ...

Grammar-based graph compression [PDF]

open access: yesInformation Systems, 2018
We present a new graph compressor that works by recursively detecting repeated substructures and representing them through grammar rules. We show that for a large number of graphs the compressor obtains smaller representations than other approaches.

A complete system of grammars for plane graphs [PDF]

open access: yes, 1979
In [1], for directed graphs, it was shown that the system of simple graph grammars is complete. In this paper, a system of grammars for plane graphs, called plane graph grammars, is introduced, and it is shown that this system is complete, ..
