“…Next, we aim to encode all the above information in the form of ontological statements (RDF-style triples) of the form: class 1-property-class 2. All the names (of persons, places, manuscripts, events, and other objects) were submitted as queries to a semantic search engine, Virtuoso server, 35 to look them up in 35 http://virtuoso.openlinksw.com/ external ontologies, such as Freebase (Bollacker et al, 2008), DBPedia (Auer et al, 2007), and Opencyc (Foxvog, 2010;Lenat et al, 2010 36 ), and in the authority files, such as VIAF, 37 LCNS,38 GETTY, 39 GND, 40 and GeoNames. 41 Once found (as shown in the last column of Table 2: links to authority files), they were linked directly by using the extracted URI or by owl:sameAs relation for similar terms in different vocabularies.…”
