Transcript of "Semantic.edu, an introduction"

  1. 1. The Semantic Web <ul><li>The state of play for liberal arts campuses </li></ul><ul><li>December 2009 </li></ul><ul><li>NITLE Research </li></ul>( http://weblogs.elearning.ubc.ca/googlescholar/archives/046534.html )
  2. 2. Today’s hour <ul><li>Agenda </li></ul><ul><li>sketch of semantic field </li></ul><ul><li>spectrum of uses (campus + world) </li></ul><ul><li>discussion of uses </li></ul><ul><li>What you can take away </li></ul><ul><li>general awareness of emerging tech </li></ul><ul><li>pointer to interesting projects </li></ul><ul><li>ideas for projects you can do </li></ul><ul><li>network with each other </li></ul>
  3. 3. What is the Semantic Web? <ul><li>A set of technologies </li></ul><ul><li>full stack includes: </li></ul><ul><ul><li>RDF </li></ul></ul><ul><ul><li>OWL </li></ul></ul><ul><ul><li>SPARQL </li></ul></ul><ul><ul><li>RDFa </li></ul></ul><ul><li>… and also NLP </li></ul>http://obitko.com/tutorials/ontologies-semantic-web/semantic-web-architecture.html
  4. 4. What is the Semantic Web? <ul><li>Policies, practices, strategies </li></ul><ul><li>interoperability (“The Semantic Web is a web of data”, W3C) </li></ul><ul><li>openness </li></ul><ul><li>linked data </li></ul><ul><li>&quot;data integration is the name of the game&quot; </li></ul><ul><li>Sir Tim Berners-Lee, 2008, </li></ul><ul><li>http://blogs.zdnet.com/semantic-web/?p=105 </li></ul>
  5. 5. What is the Semantic Web? <ul><li>businesses growing </li></ul><ul><li>Sites </li></ul><ul><li>Tools </li></ul><ul><li>Consulting </li></ul>
  6. 6. What is the Semantic Web? <ul><li>A set of technologies? </li></ul><ul><li>Web content with: </li></ul><ul><li>Identifiers </li></ul><ul><li>Exposed metadata (triples) </li></ul><ul><li>Links </li></ul><ul><li>“ By May 2009 this had grown to 4.2 billion RDF triples, interlinked by around 142 million RDF links.” </li></ul>http://en.wikipedia.org/wiki/Linked_Data
  7. 7. What is the Semantic Web? W3C, Alice in Semantic Wonderland http://www.w3.org/TR/xhtml-rdfa-primer/alice-example.html <ul><li>RDFa example </li></ul><ul><li>Properties assigned </li></ul>
  8. 8. How can this be used? <ul><li>External resources, under the hood </li></ul><ul><li>Semantic tools and services </li></ul><ul><li>Plug-ins and add-ons </li></ul><ul><li>Campus projects </li></ul><ul><li>Pedagogies and research </li></ul>
  9. 9. External resources, under the hood http://www.w3.org/2009/Talks/0830-Nanjing-IH/ http://www.readwriteweb.com/archives/google_semantic_data.php

  12. 12. Semantic tools and services <ul><li>Presentation and visualization </li></ul>( http://www.sioc.me/ ) ( http://www.sioc.me/ )
  13. 13. Plug-ins and add-ons <ul><li>Derive categories, drive suggestions </li></ul>Tagaroo for WordPress, http://tagaroo.opencalais.com/
  14. 14. Plug-ins and add-ons <ul><li>Others: </li></ul><ul><li>Zemanta, http://www.zemanta.com/ </li></ul><ul><li>Semantic Mediawiki, http://www.semanticmediawiki.org/wiki/Semantic_MediaWiki </li></ul>

  17. 17. Campus projects <ul><li>Enterprise or medium-scale architecture strategies </li></ul><ul><li>repository (example: http://dspace.nitle.org/ ) </li></ul><ul><li>general campus-housed documentation </li></ul><ul><li>revise metadata strategy and/or run local app </li></ul><ul><li>Rely on growing number of helper apps (i.e., Triplify, GRDDL, etc.) </li></ul>
  18. 18. Campus projects <ul><li>Why do such a thing? </li></ul><ul><li>Campus research and connections </li></ul><ul><li>Outreach </li></ul><ul><li>Open content - connect with some academic projects, like OAI </li></ul><ul><li>&quot;make your information more programmable&quot; (Reuters, Tim O’Reilly interview, February 2008, http://radar.oreilly.com/archives/2008/02/reuters-ceo-sees-semantic-web.html ) </li></ul>
