- QUOTE: The NERD ontology is a set of mappings established manually between the taxonomies of named entity types. Concepts included in the NERD ontology are collected from different schema types: DBpedia ontology (for DBpedia Spotlight and Lupedia), lightweight taxonomies (for AlchemyAPI, Yahoo !, Wikimeta, and Zemanta) or simple flat type lists (for Extractiv, OpenCalais, Saplo, Semitags). The NERD ontology tries to merge the linguistic community needs and the logician community ones: we developed a core set of axioms based on the Quaero schema which define the NERD core and we mapped similar concepts described in the other scheme. The selection of these concepts has been done considering the greatest common denominator among them. The concepts that do not appear in the NERD namespace are sub-classes of parents that end-up in the NERD ontology. To summarize, a concept is included in the NERD ontology as soon as there are at least three extractors that use it.
