User tagging by means of authority-free folksonomies has become standard for making online videos, photos, bookmarks and blog posts discoverable. We have proposed to design and develop a system that identifies and exposes the ontological structure that is latent in the folksonomic tags used in open, publicly available sites such as Flickr photos, YouTube video and Blogger blogs and demonstrates the ability to perform higher order processing using the induced structure. Specifically, the technology being developed will allow the system to identify photos, videos or blog posts about the same event by means of the tags applied in one medium e.g. photos in order to identify tagged items in the same medium or other media videos or blog posts. We proposed to use large-scale topic hierarchies such as Wikipedia dbPedia and lexical resources such as the Library of Congress Thesaurus for Graphic Materials in order to tokenize and disambiguate the tags into unambiguous topics. These will then be mapped onto what, when, and where slots, and used to identify depictions of the same event in other media using a formal reasoner, VIStologys BaseVISor, a forward-chaining OWLRDF reasoner using OWL 2 RL, a tractable set of axioms for reasoning about knowledge encoded as OWL triples.
