The French ANR project "Data to Knowledge in Agronomy and Biodiversity" (D2KAB) builds an archive of French agricultural alert newsletters. In order to annotate plant disease and pest, we need a new semantic resource. Several ontologies and knowledge graphs already exist on the subject but do not cover all of our needs. We have therefore developed...
