Hundreds of public SPARQL endpoints have been deployed on the Web, forming a novel decentralised infrastructure for querying billions of structured facts from a variety of sources on a plethora of topics. But is this infrastructure mature enough to support applications? For 427 public SPARQL endpoints registered on the DataHub, we conduct various(More)
As many cities around the world provide access to raw public data along the Open Data movement, many questions arise concerning the accessibility of these data. Various data formats, duplicate identifiers, heterogeneous metadata schema descriptions, and diverse means to access or query the data exist. These factors make it difficult for consumers to reuse(More)
Pour un projet de Recherche d'information, nous avons développé ON-TOLURGENCES, une ressource termino-ontologique qui assure a) le rôle de mo-dèle du domaine répertoriant tous les concepts pertinents et b) le lien entre les concepts et la façon dont ils sont nommés dans les documents du Dossier patient informatisé. Cette double fonction permet l'annotation(More)
OBJECTIVE This study shows the evolution of a biomedical observation dictionary within the Assistance Publique Hôpitaux Paris (AP-HP), the largest European university hospital group. The different steps are detailed as follows: the dictionary creation, the mapping to logical observation identifier names and codes (LOINC), the integration into a(More)
The recent demonstration of the ability of human polymorphonuclear neutrophils (PMN) to secrete various cytokines in response to the granulocyte activator granulocyte-macrophage colony-stimulating factor (GM-CSF) but not to other cytokines, has led to the identification of PMN as biosynthetically active cells. In this study we have investigated the ability(More)
L'intégration des ressources terminologiques et ontologiques d'un do-maine est un enjeu majeur en vue de leur pleine exploitation par des organisations. Cette intégration est rendue difficile par l'hétérogénéité des ressources et de leur formalisme de représentation (SKOS, BS 8723, etc.). Ces formalismes se différencient principalement par leur richesse(More)
We demo an online system that tracks the availability of over four-hundred public SPARQL endpoints and makes up-to-date results available to the public. Our demo currently focuses on how often an endpoint is online/offline, but we plan to extend the system to collect metrics about available meta-data descriptions, SPARQL features supported, and performance(More)
