Enhancing scientific information systems with semantic annotations

2013

International audience; Scientific Information Systems aim to produce or improve knowledge on a subject through activities of research and development. The management of scientific dat a requires some essential properties. We propose SemLab an architecture that sup ports interoperability, data quality and extensibility through a unique paradigm: semantic annotation. We present two app lications that validate our architecture.

Representing and Reasoning for Spatiotemporal Ontology Integration

2004

International audience; The World-Wide Web hosts many autonomous and heterogeneous information sources. In the near future each source may be described by its own ontology. The distributed nature of ontology development will lead to a large number of local ontologies covering overlapping domains. Ontology integration will then become an essential capability for effective interoperability and information sharing. Integration is known to be a hard problem, whose complexity increases particularly in the presence of spatiotemporal information. Space and time entail additional problems such as the heterogeneity of granularity used in representing spatial and temporal features. Spatio-temporal ob…

Ontologie pour l'intégration de données d'observation de la Terre et contextuelles basée sur les relations topologiques

2018

National audience; Nous proposons une ontologie pour l'intégration de données d'observation de la Terre et de donnés contextuelles, à l'aide de relations topologiques spatiales et temporelles. Cette ontologie spécialise des standards, notamment SOSA, GeoSPARQL et OWL-Time. La base de connaissance décrite par cette ontologie est alimentée grâce à un processus qui sélectionne, transforme et intègre de données géospatiales hétérogènes (méta-données d'image satellite, données météorologiques, unités administratives, couverture terrestre, etc.). Ce processus s'appuie sur le tuilage des images pour traiter les données ayant une composante spatiale fixe, alors que les relations temporelles sont ca…

Allocation des ressources dans l’informatique en brouillard le calcul du brouillard véhiculaire pour une utilisation optimale des véhicules électriqu…

2019

Abstract: Technological advancements made it possible for Electric vehicles (EVs) to have onboard computation, communication, storage, and sensing capabilities. Nevertheless, most of the time these EVs spend their time in parking lots, which makes onboard devices cruelly underutilized. Thus, a better management and pooling these underutilized resources together would be strongly recommended. The new aggregated resources would be useful for traffic safety applications, comfort related applications or can be used as a distributed data center. Moreover, parked vehicles might also be used as a service delivery platform to serve users. Therefore, the use of aggregated abundant resources for the …

Can SegFormer be a True Competitor to U-Net for Medical Image Segmentation?

2023

The U-Net model, introduced in 2015, is established as the state-of-the-art architecture for medical image segmentation, along with its variants UNet++, nnU-Net, V-Net, etc. Vision transformers made a breakthrough in the computer vision world in 2021. Since then, many transformer based architectures or hybrid architectures (combining convolutional blocks and transformer blocks) have been proposed for image segmentation, that are challenging the predominance of U-Net. In this paper, we ask the question whether transformers could overtake U-Net for medical image segmentation. We compare SegFormer, one of the most popular transformer architectures for segmentation, to U-Net using three publicl…

Contributeurs au Grand Débat National demandant un développement des pistes cyclables dans l'Hérault

2021

Le Grand Débat National, décidé par Emmanuel Macron début 2019 pour répondre au mouvement social des Gilets Jaunes, a permis de collecter les contributions de citoyens sur la transition écologique via une plateforme en ligne. Dans cet article, nous exploitons le corpus constitué par ces contributions pour identifier des zones où les participants demandent le développement de pistes cyclables et d’équipements ferroviaires. Pour cela, nous avons créé un modèle de classification permettant d’identifier les contributions traitant de la thématique du transport et proposé une méthode d’extraction de motifs traduisant les propositions des contributeurs. A l’aide des codes postaux donnés par les co…
