OntoLex

Since its publication as a W3C Community report in 2016,[2] it serves as ``a de facto standard to represent ontology-lexica on the Web´´.

The innovative element about OntoLex-Lemon is that it provides such a data model as an RDF vocabulary, as this enables novel use cases that are based on web technologies rather than stand-alone dictionaries (e.g., translation inference, see applications below).

For the foreseeable future, OntoLex-Lemon will also remain unique in this role, as the (Linguistic) Linked Open Data community strongly encourages to reuse existing vocabularies[7] and as of Dec 2019, OntoLex-Lemon is the only established (i.e., published by W3C or another standardization initiative) vocabulary for its purpose.

Selected applications include OntoLex development is regularly addressed in scientific events dedicated to ontologies, linked data or lexicography.

OntoLex-Lemon differs from these earlier models in being a native Linked Open Data vocabulary that does not (just) formalize structure and semantics of machine-readable dictionaries, but is designed to facilitate information integration between them.
