نبذة مختصرة : International audience ; Biodiversity data are characterized by their interdisciplinarity and semantic heterogeneity. They are scattered in many databases, without agreement on the harmonization of their metadata.Among the thesauri dedicated to the Environment, listed at European or international level, most respect the formats and recommendations of the semantic web, but none specializes in the "Biodiversity" theme.To enable researchers to better share and reuse their data, we undertook the constitution of the Biodiversity Thesaurus, bilingual French / English, on the ecological components of biodiversity. It respects ISO international standards and complies with W3C Linked Open Data rules in order to achieve semantic interoperability (URI-concepts, SKOS / RDF format). This resource is freely available (CC BY license) and follows the FAIR principles.The GDR SemanDiv research group (led at CEFE-CNRS) was created with the aim of fostering collaboration between ecological researchers, computer scientists and documentalists on the semantics of biodiversity.Project development:-Publishing of Biodiversity Thesaurus on the Loterre platform (Linked Open TERminology REsources): visualization, browsing and access to an RDF triple store; on the AgroPortal ontology repository;-Collaborative management with domain experts: reviewing of definitions;-Enrichment by terminology extraction from scientific literature;-Alignments with other European/international semantic resources (Agrovoc, GEMET, EnvThes, ENVO.) serving as a hub for interconnections;-Evolution towards an ontology of biodiversity;-Text and data mining support;-Integration of these termino-ontological resources into terminology services, ecological database directories, biodiversity observatory metadata portals or environmental data repositories. ; Les données de biodiversité se caractérisent par leur interdisciplinarité et leur hétérogénéité sémantique. Elles sont disséminées dans de nombreuses bases de données, sans concertation sur l’harmonisation de leurs ...
