The resulting datasets include grammatical gender (for entities of type person), lexicalizations (alternative names for entities and concepts), topic signatures (strongest related terms), and thematic concepts (the main subject entities/concepts for Wikipedia categories). 2.3.2.3 Datasets and Resources The output of each DBpedia extractor, for each language, is made available as a separate dataset. All datasets are provided in two serializations: as Turtle (N-triples) and as Turtle quads (N-Quads, which include context). The datasets can be divided into the following categories: • DBpedia Ontology: The latest version of the ontology that was used while extracting all datasets. • Core datasets: All infobox-based and specific feature extractors (including the ones listed in Table 2.3) belong here. • Links to other datasets: DBpedia is interlinked with a large number of knowledge bases. The datasets in this group provide links to external resources both on the instance level (owl:sameAs), e.g., to Freebase and YAGO, and on the schema level (owl:equivalentClass and owl:equivalentProperty), most notably to schema.org. • NLP datasets: This last group corresponds to the output of the statistical extractors. Namespaces and Internationalization The generic DBpedia URI namespaces are listed in the upper block of Table 2.4. As part of the internationalization efforts, some datasets are available both in localized and in canonicalized version.
