Topic Map conversion of YSO

Revision as of 14:34, 14 August 2008

YSO is the Finnish General Upper Ontology based on the Finnish General Thesaurus maintained by The National Library of Finland. YSO contains ca. 20 000 concepts. The Finnish General Thesaurus was converted to YSO by Semantic Computing Research Group (SECO) during FinnONTO project. Detailed description of YSO is available at Tietolinja magazine 1/2007 (in Finnish).

Topic Map conversion of YSO is based on RDF dump kindly provided by the SECO team. Topic Map YSO was created using Wandora's RDF import feature. Machine translated YSO was processed manually to fix topic names and associations. Topic Map conversion is not identical to RDF version. Differences are discussed below.
