The Semantic Computing group at Bielefeld University [1] is happy to announce the first release of an English lexicon for DBpedia in lemon [2] format: It comprises 1,217 verbalizations covering 353 classes as well as 300 properties (all those that have more than 10,000 occurrences in the DBpedia dataset). It can prove useful for a wide range of ontology-based NLP applications, such as question answering and natural language generation from RDF or SPARQL. We invite you to browse and use the lexicon, and would love to get feedback. Also, everyone is welcome to improve the lexicon, extend it, and port it to other languages (we are currently working on an initial version of a Spanish and a German lexicon). The source is available on GitHub:

Nice work!



If you have a SPARQL 1.1 database/store at your disposal it boils down to:

PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX wdrs: <http://www.w3.org/2007/05/powder-s#>
PREFIX vocab: <http://open.vocab.org/terms/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

LOAD <http://lemon-model.net/lemon.ttl> ;

INSERT {GRAPH <http://lemon-model.net/lemon.ttl>
            {    ?s rdfs:isDefinedBy <http://www.lemon-model.net/lemon#> .
                <http://www.lemon-model.net/lemon#> vocab:defines ?s .
                <http://www.lemon-model.net/lemon#> a owl:Ontology .
                ?s wdrs:describedby <http://lemon-model.net/lemon.ttl> .
                <http://lemon-model.net/lemon.ttl> foaf:primaryTopic ?s .
            }
        }
WHERE {GRAPH <http://lemon-model.net/lemon.ttl> {
                                                {?s rdfs:subClassOf ?o}
                                                UNION
                                                {?s rdfs:subPropertyOf ?o}

                                                UNION {?s a ?o}
                                            }
    }

I've applied the relations in question to some of our instances [1].

BTW -- could you add some rdfs:isDefinedBy relations to your ontology? This makes the ontology description graph much more navigable using follow-your-nose pattern. UNION {?s owl:equivalentClass ?o} UNION {?s owl:equivalentProperty ?o} [1] http://linkeddata.uriburner.com/describe/?url=http%3A%2F%2Fwww.lemon-model.net%2Flemon%23 -- URIBurner instance
