Output
Returns matching EuroVoc concepts including their unique URIs, preferred labels in the requested languages, alternative labels (synonyms/entry terms), and hierarchical context through broader terms (hypernyms), narrower terms (hyponyms), and related concepts within the EuroVoc thesaurus structure.
Example use cases
Tagging EU documents with EuroVoc descriptors
“I need to tag a legal document about environmental policy — can you resolve the term 'climate change' in EuroVoc and give me the official concept URI and preferred labels in English, French, and German so I can use them as index descriptors?”
Building a multilingual legal glossary
“I'm building a glossary of EU legal terms. Can you look up 'competition law' in the EuroVoc thesaurus and return its preferred and alternative labels in English, Spanish, and Italian, plus any related concepts?”
Exploring EuroVoc hierarchy for a research topic
“What are the broader and narrower EuroVoc concepts around the term 'intellectual property'? I want to understand where it sits in the EU vocabulary hierarchy and find related terms I might be missing.”
