Transcript of "Linked Data and SKOS"

  1. 1. Linked Data and SKOS2011 Workshop on Physics Classification, BostonNovember 28th, 2011Bernhard Haslhofer | Cornell University, Information Science
  2. 2. Linked Data2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011
  3. 3. Web Architecture HTML HTML HTML hyperlinks hyperlinks2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011
  4. 4. But sometimes we need programmatic access the underlying content, metadata, and vocabularies.2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011
  5. 5. Web APIs API API API API API2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011
  6. 6. Web APIs - Drawbacks • Each Web API has a proprietary interface • Datasources must be known in advance • Information entities (papers, authors, subjects, etc.) are not linked2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011
  7. 7. Linked Open Data Vision • Publish and link structured data on the Web • Create a single global data space based on the Architecture of the World Wide Web RDF RDF RDF RDF links RDF links2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011

  9. 9. Publishing Linked Data • Distinguish between non-information (NIR) and information resource (IR) • Sample NIR • http://arxiv.org/resource/cond-mat/0512091 • Sample IRs • http://arxiv.org/abs/cond-mat/0512091 (HTML) • http://arxiv.org/data/cond-mat/0512091 (RDF)2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011
  10. 10. The Simple Knowledge Organization System (SKOS)2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011
  11. 11. What is SKOS? • A language for describing controlled vocabularies (taxonomies, classification schemes, thesauri) • Builds on Linked Data principles2011 Workshop on Physics Classification | Boston, MA | Nov. 28th, 2011
