Overlapping Community Detection Optimization and Nash Equilibrium
Michel Crampes, Michel Plantié
Community detection using both graphs and social networks is the focus of many algorithms. Recent methods aimed at optimizing the so-called modularity function proceed by maximizin…
Visualizing and Interacting with Concept Hierarchies
Michel Crampes, Michel Plantié
Concept Hierarchies and Formal Concept Analysis are theoretically well grounded and largely experimented methods. They rely on line diagrams called Galois lattices for visualizing…
A Unified Community Detection, Visualization and Analysis method
Michel Crampes, Michel Plantié
Community detection in social graphs has attracted researchers' interest for a long time. With the widespread of social networks on the Internet it has recently become an important…
User Centered and Ontology Based Information Retrieval System for Life Sciences
Sylvie Ranwez, Vincent Ranwez, Mohameth-François Sy +2
Because of the increasing number of electronic data, designing efficient tools to retrieve and exploit documents is a major challenge. Current search engines suffer from two main d…
Ontology-Supported and Ontology-Driven Conceptual Navigation on the World Wide Web
Michel Crampes, Sylvie Ranwez
This paper presents the principles of ontology-supported and ontology-driven conceptual navigation. Conceptual navigation realizes the independence between resources and links to f…
