    8. Why Tagging Matters?
    9. It’s Popular. Source: http://www.flickr.com/photos/matthewfield/2306001896/ Reference: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    10. It’s Popular. “Today, practically anyone who uses a computer or the Internet is exposed to tagging in some way.” Source: http://www.flickr.com/photos/matthewfield/2306001896/ Reference: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    11. It’s Multifaceted. Source: http://www.flickr.com/photos/missizss/2418518837/ Reference: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    12. It’s Multifaceted. “As tagging grows in popularity, the idea that the same thing can exist in multiple places will be the norm.” Source: http://www.flickr.com/photos/missizss/2418518837/ Reference: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    13. It’s Social. Source: http://www.flickr.com/photos/pulguita/2868952310/ Reference: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    14. It’s Social. “Through the most popular tags, we can see a kind of rough consensus on the subject of the resouce.” Source: http://www.flickr.com/photos/pulguita/2868952310/ Reference: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    15. It’s Flexible. Source: http://www.flickr.com/photos/samuelr/3040787155/ Reference: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    16. It’s Flexible. “Tagging offers organizations a way to learn, understand, and adopt the vocabulary of their communities.” Source: http://www.flickr.com/photos/samuelr/3040787155/ Reference: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    17. Basic Model
    18. User Resource Tags Tagging System Source: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    19. User Resource “Taggers create the tags, and sometimes they add resources.” Tags Tagging System Source: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    20. User Resource “As long as we have a way to uniquely identify something, it can be tagged.” Tags Tagging System Source: Gene Smith, Tagging: People-Powered Metadata for the Social Web
    21. User Resource “Because tagging is open-ended, tags can be just about any kind of term.” Tags Tagging System Source: Gene Smith, Tagging: People-Powered Metadata for the Social Web

    25. Let’s Share Tags!
    26. Value by Sharing
    27. Collaborative Sharing Across Multiple Applications Source: http://www.flickr.com/photos/yourdon/3088582622/ Reference: Tom Gruber, Ontology of Folksonomy: A Mash-Up of Apples and Oranges
    28. Collaborative Filtering Based on Tagging Source: http://www.flickr.com/photos/moosterbroek/2948816723/ Reference: Tom Gruber, Ontology of Folksonomy: A Mash-Up of Apples and Oranges
    29. Connecting People Based on Tagging Source: http://www.flickr.com/photos/jmcphers/117976932/ Reference: Haklae Kim et al., Social Semantic Cloud of Tag: Semantic Model for Social Tagging
    30. How Do We Do This?
    31. Tag Ontologies
    32. Ontology is NOT a Taxonomy Source: http://www.flickr.com/photos/thebusybrain/2492945625/ Reference: Tom Gruber, Ontology of Folksonomy: A Mash-Up of Apples and Oranges
    33. Ontology Makes Semantic Agreement Source: http://www.flickr.com/photos/mujitra/2933605871/ Reference: Tom Gruber, TagOntology: A Way to Agree on the Semantics of Tagging Data
    34. Semantic Agreement Enables Useful Composition Source: http://www.flickr.com/photos/ejpphoto/2314610838/ Reference: Tom Gruber, TagOntology: A Way to Agree on the Semantics of Tagging Data
    35. System A says a tag is a property of a document. System B says a tag is an assertion by an individual with an identity. Does it mean anything to combine the tag data from these two systems? Nah. If system A and B agree that a tagging is an assertion tagged(tag, resource, user), they share, exchange, and reuse tagging data across the systems. Reference: Tom Gruber, TagOntology: A Way to Agree on the Semantics of Tagging Data
