With hundreds of millions of active web sites on the web and millions of
new web pages added every day, the knowledge contained on the internet far
surpasses even the largest cache of big data. Today, many web developers
still publish web pages and services solely for human consumption.
However, there is a growing movement to put machine friendly data on the
web in various forms to create a web of Linked Data rather than a web
comprised of simple documents.

This talk will examine the history, technology and examples around Linked
Data, onotologies, and the schema.org movement that will enable a smarter
web -- not just for search, but also next-gen data tools and applications
that will connect entities and facts from across the internet, all enabled
by developers publishing data directly to the web.

  3. 3. Original Web • Collections of documents • Users “surfed” • Created mostly for human consumption
  4. 4. Web of Today • Trillions of web pages • 5 billion web pages change every day • 1000x more web pages on the “deep web”
  5. 5. Machine-driven Web

  8. 8. 2009
  9. 9. Five Star Open Data Make your stuff available on the web Make it available as structured data Use non-proprietary formats Use URIs to denote things, so people can link to your data Link your data to other data
  10. 10. RDF Ontology: FOAF <jaymyers> <foaf:knows> <arun> <arun> <foaf:knows> <billybob> A machine could infer that Jay might like to know Billy Bob <billybob> <foaf:interest> “Arduino” <jaymyers> <foaf:interest> “Arduino”
  11. 11. RDF Ontology: GoodRelations <wafflemaker> a gr:ProductOrService ; <wafflemaker> <gr:category> ‘Waffle_Makers’ “Show me the names of all ‘lightweight’ waffle makers” <wafflemaker> <gr:name> ‘Euro Cuisine 8" Heart-Shape Waffle Maker’ <wafflemaker> <gr:weight> ”2.0"^^xsd:float .

  13. 13. “Show me music artists whose hometown is Minneapolis”
  14. 14. Hydra and JSON-LD • Machine-readable vocabulary that can be used to describe web APIs • Puts the information back in APIs by defining small contract that sets JSON structures and URLs • Creates new breed of web APIs (powered by Linked Data) using decentralized, reusable contracts
  15. 15. 2010
  16. 16. schema.org • Common vocabularies that search engines can understand • Lower the bar for webmasters to publish linked data on the web in their HTML • Improve user experience through data

  19. 19. Looks Like We’ve Got Something Here! • 15% of all sites contain schema.org markup • Many major sites • Adoption by content systems like Drupal and Wordpress • Around 1200 object types and growing (people, places, products, etc)
  20. 20. Practical Applications in Search Yahoo! Related Entities
  21. 21. Practical Applications in Search Yandex Islands
  22. 22. Practical Applications in Search Google Knowledge Graph Additional content driven by schema.org derived data
  23. 23. Other Applications Pinterest Rich Pins
  24. 24. Time To Get On Board! • US, UK gov’t • BBC • Flickr • Google • Yahoo! • Bing • Last.fm • Facebook • New York Times • Sears • IBM • O’reilly • Volkswagen • IMDB • Elsevier • Fujitsu • Alchemy API • Many more…
