Abstract. In knowledge bases, the open world assumption and the ability to express variables may lead to an answer redundancy problem. This problem occurs when the returned answers...
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...
Conceptual Graphs and Formal Concept Analysis have in common basic concerns: the focus on conceptual structures, the use of diagrams for supporting communication, the orientation b...
Abstract We describe the ‘Hierarchical as View’ approach to knowledge integration from heterogeneous sources. This is based on a novel representation called Layered Conceptual ...
