Theoretical Aspects of Scheduling Coupled-Tasks in the Presence of Compatibility Graph

2012

International audience; This paper presents a generalization of the coupled-task sche-duling problem introduced by Shapiro \cite{Shapiro}, where considered tasks are subject to incompatibility constraints depicted by an undirected graph. The motivation of this problem comes from data acquisition and processing in a mono-processor torpedo used for underwater exploration. As we add the compatibility graph, we focus on complexity of the problem, and more precisely on the boundary between $\mathcal{P}$ and $\mathcal{NP}$-completeness when some other input parameters are restricted (e.g. the ratio between the durations of the two sub-tasks composing a task): we adapt the global visualization of …

INCONSISTENCY IDENTIFICATION IN DYNAMIC ONTOLOGIES BASED ON MODEL CHECKING

2012

International audience; The increasing use of ontologies and the cost of changes support the need to manage the evolution of ontologies. A common kind of error in ontology evolution is the logical contradiction declined as incoherences and inconsistences. In this paper, we propose a new approach to predict and identify the incoherences and inconsistences in the evolution of ontologies based on temporal logic and ontology design patterns. We implement the proposed approach using the NuSMV model checker. Based on these patterns, we propose an automated process to guide and monitor the implementation of change while ensuring the consistency of the evolved ontology.

Détection de précurseurs d'évènements basés sur les motifs dans les réseaux sociaux

2021

Les données issues des réseaux sociaux suscitent l'intérêt des chercheurs qui développent des algorithmes et des modèles d'apprentissage automatique pour analyser les interactions et les comportements des utilisateurs. Ces méthodes s'appuient sur la topologie du réseau pour représenter les changements structurels et pour détecter des précurseurs remarquables précédant généralement des évènements majeurs. L'étude présentée dans cet article vise à étudier si certains graphlets (motifs spécifiques) peuvent être considérés comme des précurseurs d'évènements. Nous expérimentons la méthode proposée sur trois ensembles de données de réseaux sociaux. Nous étudions également le rôle joué dans les gr…
