Semantic Web For Distributed Social Networks

  1. Semantic Web for Distributed Social Networks http://www.flickr.com/photos/matthewfield/ David Peterson BoaB interactive http://www.flickr.com/photos/matthewfield/
  2. Semantic Web • What? • Hype - Scientific American 2001 • “... will unleash a revolution of new possibilities... ” • Reality - Scientific American 2007 • “The Semantic Web In Action”

  4. Shared Meaning http://www.flickr.com/people/davidsethp/
  5. Information is object & collection based http://www.flickr.com/photos/mcbeth/
  6. Distributed Social Network • You own the data • You control access • You can pull it/change it • You can delete it • You can decide what is best • “YOU” http://www.flickr.com/photos/tychay/
  7. Ingredients • Shared Understanding • Central Identity • Global Graph
  8. Shared http://www.flickr.com/photos/belmore/
  9. Tagging • Labelling our stuff • Now what? • What does ‘Paris’ and ‘Paris’ *really mean*?
  10. Shared linking != shared understanding • technorati tags • Drupal, Wordpress, Live Writer, etc... • Creates some sort of emergent meaning, but still we are just talking about matching strings of characters :-(
  11. Concept Tagging • Freebase
  12. microformats to the rescue • Organic formation • Actual meaning is being encoded • Structure emerges http://www.flickr.com/photos/samoube/
  13. Now we are cooking with gas... shared meaning http://www.flickr.com/photos/eole/
  14. But wait. What happens when I want more... • hCard • hCalendar • hReview • hListing • hResume • XFN • rel-license http://www.flickr.com/photos/jcocinero/
  15. Vocabularies • Now we can describe anything but what do we name it? • Roll your own • Or better yet, re-use http://www.flickr.com/photos/sir_fish/
  16. Ontologies http://www.flickr.com/photos/iskanderstruck/
  17. Ontologies • Umbrella Ontologies help create strong and weak ties http://www.flickr.com/photos/iskanderstruck/
  18. Ontologies • Umbrella Ontologies help create strong and weak ties • UMBEL http://www.flickr.com/photos/iskanderstruck/
  19. Ontologies • Umbrella Ontologies help create strong and weak ties • UMBEL • Dbpedia http://www.flickr.com/photos/iskanderstruck/
  20. Ontologies • Umbrella Ontologies help create strong and weak ties • UMBEL • Dbpedia • OpenCyc http://www.flickr.com/photos/iskanderstruck/

  22. FOAF http://www.flickr.com/photos/beija-flor/
  23. FOAF It’s all about who you know ... http://www.flickr.com/photos/beija-flor/
  24. and who you don’t want to ...
  25. • OpenID • RDFauth http://www.flickr.com/photos/dan_dan/

  29. “It's not the documents, it is the things they are about which are important. Obvious, really.” Tim Berners-Lee http://www.flickr.com/people/tscarlisle/
  30. From the web of documents to the web of things http://www.flickr.com/photos/vardhana/
  31. “If the graph of people is cool, imagine a graph of everything” Dries Buytaert

  34. Mobile dbpedia
  35. it's all coming together now
  36. http://www.flickr.com/photos/m500/ How can we build this thing?
  37. Tools • Semantic Mediawiki • Drupal • Simile Exhibit & Timeline • D2RQ • PHP - ARC & Triplify • .Net - linq2RDF • Java - Sesame & Elmo
  38. SMW • Structured data • Linked data • SPARQL querying • Semantic forms • Semantic maps
  39. Chickipedia is the world's largest web-based, women-based, wiki-based database of hot chicks on the planet. It is entirely user generated, making it the first female-only encyclopedia of the people, by the people, and for the people ext

  41. The Trouble with SMW http://www.flickr.com/people/davidsethp/
  42. The Trouble with SMW • Why not use this as the only thing? http://www.flickr.com/people/davidsethp/
  43. The Trouble with SMW • Why not use this as the only thing? • Permissions, or actually, the lack thereof http://www.flickr.com/people/davidsethp/
  44. The Trouble with SMW • Why not use this as the only thing? • Permissions, or actually, the lack thereof • Almost impossible to really lock it down http://www.flickr.com/people/davidsethp/
  45. The Trouble with SMW • Why not use this as the only thing? • Permissions, or actually, the lack thereof • Almost impossible to really lock it down • lots of hacking and then patching http://www.flickr.com/people/davidsethp/
  46. The Trouble with SMW • Why not use this as the only thing? • Permissions, or actually, the lack thereof • Almost impossible to really lock it down • lots of hacking and then patching • and still things come through http://www.flickr.com/people/davidsethp/
  47. Drupal 5
  48. Drupal 5 • FOAF
  49. Drupal 5 • FOAF • Neologism
  50. Drupal 5 • FOAF • Neologism • RDFCCK
  51. Drupal 5 • FOAF • Neologism • RDFCCK • Open Calais
  52. Drupal 5 • FOAF • Neologism • RDFCCK • Open Calais • MOAT
  53. The trouble with Drupal 5 http://www.flickr.com/people/davidsethp/
  54. The trouble with Drupal 5 • It’s not 6 http://www.flickr.com/people/davidsethp/
  55. The trouble with Drupal 5 • It’s not 6 • Weird to-and-fro, confusion http://www.flickr.com/people/davidsethp/
  56. The trouble with Drupal 5 • It’s not 6 • Weird to-and-fro, confusion • Some modules no longer maintained http://www.flickr.com/people/davidsethp/
  57. The trouble with Drupal 5 • It’s not 6 • Weird to-and-fro, confusion • Some modules no longer maintained •A lot of the good stuff is in 6 & 7 http://www.flickr.com/people/davidsethp/
  58. Drupal 6 http://www.flickr.com/photos/iskanderstruck/
  59. Drupal 6 • Way better than 5 http://www.flickr.com/photos/iskanderstruck/
  60. Drupal 6 • Way better than 5 • RDF API http://www.flickr.com/photos/iskanderstruck/
  61. Drupal 6 • Way better than 5 • RDF API • SPARQL http://www.flickr.com/photos/iskanderstruck/
  62. Drupal 6 • Way better than 5 • RDF API • SPARQL • Open Calais http://www.flickr.com/photos/iskanderstruck/
  63. Drupal 6 • Way better than 5 • RDF API • SPARQL • Open Calais • RDFCCK http://www.flickr.com/photos/iskanderstruck/
  64. Drupal 6 • Way better than 5 • RDF API • SPARQL • Open Calais • RDFCCK • Exhibit http://www.flickr.com/photos/iskanderstruck/
  65. The trouble with 6!! http://www.flickr.com/people/psmithson/
  66. The trouble with 6!! • It is not 5! http://www.flickr.com/people/psmithson/
  67. The trouble with 6!! • It is not 5! • Core features are still in RC and beta stages??? WTF http://www.flickr.com/people/psmithson/
  68. The trouble with 6!! • It is not 5! • Core features are still in RC and beta stages??? WTF • Some important modules are still 5 only http://www.flickr.com/people/psmithson/
  69. The trouble with 6!! • It is not 5! • Core features are still in RC and beta stages??? WTF • Some important modules are still 5 only • Panels, FOAF, MOAT http://www.flickr.com/people/psmithson/
  70. The trouble with 6!! • It is not 5! • Core features are still in RC and beta stages??? WTF • Some important modules are still 5 only • Panels, FOAF, MOAT • A lot of the good stuff is coming in 7 (sound familiar?) http://www.flickr.com/people/psmithson/
  71. Why can’t we be friends... http://www.flickr.com/photos/greentea/
  72. ARC
  73. Triplify
  74. SPARQL queries • Federated / distributed search • Structured search • Security via HTTP auth http://www.flickr.com/photos/girl-inchoate/
  75. RDFa and microformats • Indexed by Sindice and Search Monkey • Sindice is the global query engine of the Structured Web (aka Semantic Web)
  76. Some RDFa users • Creative Commons For instance, Creative Commons has recently started to deploy RDFa across the web in the form of copyright and licensing information Every time a Creative Commons user selects • DIGG CC license, the generated HTML badge contains RDFa markup indicating the nature of the license. The Creative Commons Infobar uses this data to selectively trigger on pages that declare their license using structured markup: DIGG
  77. RDFa • What does it look like?
