Integrating social tagging data: Upper Tag Ontology (UTO)

Data mediation and interoperation have already become one of the central topics of IT for decades. Since the Web appears, this problem has been exploded due to the increasing amount of data and Web users. This paper takes look at the social tagging behavior. It proposes upper tag ontology (UTO) to model tag data from three popular social tagging networks (del.icio.us, youTube, flickr). In this paper, we discuss how to crawel tag data and store them according to UTO in RDF triple store. Furthermore, based on integrated RDF triple store, we provide three scenarios to show the search possibility of the integrated tag data.
