OpenTagging Platform <ul><li>an open framework that is scalable and interoperable with all existing tagging data from heterogeneous sources or applications </li></ul><ul><li>http://opentagging.org </li></ul><ul><li>Goals </li></ul><ul><ul><li>to make tagging data open, more universal, and apply it across any number of social tagging sites </li></ul></ul><ul><ul><li>Through continuously user participations on the platform, users can make their customized folksonomies to organize their data by their needs and interests </li></ul></ul><ul><ul><li>The interaction of diverse objects such as users, tags, and resources on the platform brings emergent semantics of tagging data and leverages social connections among participants </li></ul></ul>

Tag Ontologies for Data Format <ul><li>Structure and Semantics for Tagging data </li></ul><ul><ul><li>Gruber’s conceptual idea ( http://tomgruber.org/writing/ontology-of-folksonomy.htm ) </li></ul></ul><ul><ul><li>Richard Newman’s Tag Ontology ( http://www.holygoat.co.uk/projects/tags ) </li></ul></ul><ul><ul><li>Torben Knerr’s Tagging Ontology ( http://code.google.com/p/tagont/ ) </li></ul></ul><ul><ul><li>Tag Schema ( http://tagschema.com/blogs/tagschema/ ) </li></ul></ul><ul><ul><li>Henry Story’s Tagging Schema ( http://blogs.sun.com/bblfish/entry/search_tagging_and_wikis ) </li></ul></ul><ul><li>Sharing and Exchanging for Tagging data </li></ul><ul><ul><li>Tagcommons.org ( http://tagcommons.org ) </li></ul></ul><ul><ul><li>Social Semantic Cloud of Tags ( http://scot-project.org ) </li></ul></ul><ul><ul><li>A Meaning of Tag ( http://moat-project.org ) </li></ul></ul>

Gruber’s Conceptual Model <ul><li>Core Concepts </li></ul><ul><ul><li>Tag: a word or phrase that is recognizable by people and computers </li></ul></ul><ul><ul><li>Object: a thing to be tagged, identifiable by a URI or a similar naming service </li></ul></ul><ul><ul><li>Tagger: someone or thing doing the tagging, such as the user of an application </li></ul></ul><ul><ul><li>Tagged: the assertion by Tagger that Document should be tagged with Term </li></ul></ul><ul><ul><li>Tagging(Object, Tag, Tagger, Source) </li></ul></ul>
