Semantic acyclicity on graph databases [PDF]
Proceedings of the 32nd ACM SIGMOD-SIGACT-SIGAI symposium on Principles of database systems, 2013 Summary: It is known that unions of acyclic conjunctive queries (CQs) can be evaluated in linear time, as opposed to arbitrary CQs, for which the evaluation problem is NP-complete. It follows from techniques in the area of constraint-satisfaction problems that semantically acyclic unions of CQs -- i.e., unions of CQs that are equivalent to a union of ...

Context-free path querying with all-path semantics using matrices with sets of intermediate vertices [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2021 The study considers the problem of context-free path querying with all-path query semantics. This problem consists in finding all paths of the graph, the labels on the edges of which form words from the language generated by the input context-free ...

Towards a Semantics-Based Recommendation System for Cultural Heritage Collections
Applied Sciences, 2023 While the use of semantic technologies is now commonplace in the cultural heritage sector and several semantically annotated cultural heritage datasets are publicly available, there are few examples of cultural portals that exploit these datasets and ...

House of Graphs: A database of interesting graphs
Discrete Applied Mathematics, 2013 In this note we present House of Graphs (http://hog.grinvin.org) which is a new database of graphs. The key principle is to have a searchable database and offer -- next to complete lists of some graph classes -- also a list of special graphs that already turned out to be interesting and relevant in the study of graph theoretic problems or as ...

A graph rewriting programming language for graph drawing [PDF]
, 1998 This paper describes Grrr, a prototype visual graph drawing tool. Previously there were no visual languages for programming graph drawing algorithms despite the inherently visual nature of the process.

An approach for system analysis with model-based systems engineering and graph data engineering
Data-Centric Engineering, 2022 Model-based systems engineering (MBSE) aims at creating a model of a system under development, covering the complete system with a level of detail that allows to define and understand its behavior and enables to define any interface and work package ...
