We present a general method to improve computation of answer sets by analyzing structural properties of normal logic programs. Therefore we use labeled directed graphs associated t...
Discovering the complex relationships between entities is one way of benefitting from the Semantic Web. This paper discusses new approaches to implementing -operators into RDF quer...
In this paper we propose a conductance electrical model to represent weighted undirected graphs that allows us to efficiently compute approximate graph isomorphism in large graph...
In recent years, innovation in technologies such as web services, business process automation, etc., have motivated a new paradigm in the application development field to appear, k...
Graph transformation systems have been introduced for the formal specification of software systems. States are thereby modeled as graphs, and computations as graph derivations acco...
