Slide 1: MOAT Meaning Of A Tag Alexandre Passant - http://apassant.net LaLIC, Université Paris-Sorbonne ESWC Linked Data BOF 1st June 2008

Slide 2: Goals • A solution to solve free-tagging issues (ambiguity, heterogeneity, lack of orgnisation) • An ontology to represent global and local meaning of tags in a machine-understandable way, using URIs of LOD resources • A framework to assign and share meanings to tags in a collaborative and open way • A process to create Linked Data from simple tagging actions
