  • 3. Micro-blogging
    Sending and publishing brief text media or micromedia
    Content ranges from News, and self-promotion, conversations, pass-along values to babbles and spam
    Today we call blogging under 140 characters, micro-blogging
  • 4. Micro-blogging services
  • 5. Linked Data
    According to Sir Tim Berners-Lee, To have our data linked properly, we have to
    Use URIs as names for things
    Use HTTP URIs so that people can look up those names
    When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)
    Include links to other URIs. so that they can discover more things
  • 6. More Linked data
    The WWW with Linked data Seems like a Giant Global Graph
    Which is content + pointers + relationships + descriptions
  • 7. Tweet…Tweet…
    Answer just a single question: “what are you doing?” in just 140 characters
    50 million live accounts
    Using proprietary software
    Tagging mechanism (#hashtags)
    Centralized service
    Twitter blocks visualizes your network
  • 8. Identi.ca
    Based on StatusNet (previously called laconi.ca)
    Free software (you may read it open source)
    Licensed under Aferro GPL version 3+
    RDF friendly
    Exports user’s social network in foaf format
    Twitter-compatible API
    Cross-posting to Twitter
    Facebook Integration
    Automatic URL-shortening
    And Group mechanism
  • 9. Semantic Micro-blogging
    We want data to be linked
    In other words We wanted them to be semantic-web-friendly
    In this case we need our updates to be
    accessible
    Machine-understandable
    Machine-reasonable
    And contain Reusable data
  • 10. Where are we?
    Some research and modeling has been made by John Breslin and colleagues (http://smob.sioc-project.org)
    FOAF and SIOC Ontologies
    Automatic/manual annotation in micro-blog posts
    Linking existing URIs of the related concepts
    Distributed architecture
  • 11. Ideas (not new, not done yet)
    Extensive use of URIs for users, topics, places…everything
    Commitment of social network services to open standards (FOAF, SBIC, DOAP, etc.)
    Semantics-oriented aggregators and clients
