OpenAgris

OpenAgris is a Web application entirely based on RDF

OpenAgris aggregates information from different data sources to expand the AGRIS knowledge about a topic or a document

OpenAgris is a linked-data environment that mashes-up various interlinked datasets, which will be combined to create meaningful results

Currently, the RDF-ization process has produced nearly 60 million triples

OpenAgris uses the Agrovoc thesaurus as backbone to interlink to other existing datasets (DBPedia, WorldBank, Geopolitical Ontology…)

DEMO 2: AgroTagger202.73.13.50:58301/AgroTagger/index.jsp

We indexed almost 27.000 WB documents and for nearly 95% of them we were able to extract Agrovoc keywords.
