A combinatorial approach to conceptual graph projection checking
We exploit the combinatorial structure of conceptual graphs in order to obtain faster execution time when computing projection, which is a core generalisation-specialisation relat...

Hierarchical Knowledge Integration Using Layered Conceptual Graphs
Abstract We describe the ‘Hierarchical as View’ approach to knowledge integration from heterogeneous sources. This is based on a novel representation called Layered Conceptual ...

Consistency Checking of Conceptual Models via Model Merging
Requirements elicitation involves the construction of large sets of conceptual models. An important step in the analysis of these models is checking their consistency. Existing re...

Expressive security policy rules using Layered Conceptual Graphs
A method must be provided to support the analysis of security policy rules interdependencies in a (possibly distributed) environment. We propose a Conceptual Graphs based language...

Consistency checking for Euclidean spatial constraints: a dimension graph approach
In this paper, we address the problem of consistency checking for Euclidean spatial constraints. A dimension graph representation is proposed to maintain the Euclidean spatial con...
