YAGO (Yet Another Great Ontology) is a knowledge base developed at the Max Planck Institute for Computer Science in Saarbrücken. It is automatically extracted from Wikipedia and other sources. As of 2012, YAGO2s has knowledge of more than 10 million entities and contains more than 120 million facts about these entities.〔(【引用サイトリンク】accessdate=2015-01-24 )〕 The information in YAGO is extracted from Wikipedia (e.g., categories, redirects, infoboxes), WordNet (e.g., synsets, hyponymy), and GeoNames.〔Fabian M. Suchanek, Gjergji Kasneci and Gerhard Weikum. "Yago - A Core of Semantic Knowledge". 16th international World Wide Web conference (WWW 2007) ()〕 The accuracy of YAGO was manually evaluated to be above 95% on a sample of facts.〔(【引用サイトリンク】accessdate=2015-01-24 )〕 To integrate it to the linked data cloud, YAGO has been linked to the DBpedia ontology〔(【引用サイトリンク】accessdate=2015-01-24 )〕 and to the SUMO ontology.〔(【引用サイトリンク】accessdate=2012-12-21 )〕 YAGO2s is provided in Turtle and tsv formats. Dumps of the whole database are available, as well as thematic and specialized dumps. It can also be queried through various online browsers () and through a SPARQL endpoint hosted by OpenLink Software. YAGO has been used in the Watson artificial intelligence system.〔David Ferrucci, Eric Brown, Jennifer Chu-Carroll, James Fan, David Gondek, Aditya A. Kalyanpur, Adam Lally, J.
