This application will scan an ontology (given in some RDF serialization) and match classes and/or individuals with entities in wikidata.
Command line usage:
wd-ontomatch -d ontomatcher -i envo.owl match_classes
This will produce a file CACHE.ttl that contains skos:closeMatch triples, as well as rdfs:label triples for all matching entities.
This can then be used in combination with rdf_matcher:
rdfmatch -f tsv -l -i envo.owl -i CACHE.ttl exact
wd-ontomatch -d ontomatcher -i $* -a wikidata_ontomatcher:save_frequency=0.05 -a wikidata_ontomatcher:cached_db_file=matches/wd-$*-cache.ttl match_all
