News Content APIs <ul><li>NPR, NYT, The Guardian </li></ul><ul><ul><li>RESTful API with XML, JSON, or ATOM </li></ul></ul><ul><ul><li>New revenue opportunities </li></ul></ul><ul><li>Uniform access or content silos? </li></ul><ul><ul><li>Proprietary schemas </li></ul></ul><ul><ul><li>Linking across APIs </li></ul></ul><ul><ul><li>Linking to external data sources (e.g. DBPedia, data.gov) </li></ul></ul><ul><ul><li>Need for a universal query language </li></ul></ul>
  • 5. Semantic Web Technologies Semantic Web aka Web 3.0 Linked Data Cloud RDF SPARQL OWL SKOS
  • 6. Semantic Web Business Case 1 Semantic Search (apple the fruit vs. apple the company) Beyond Google keyword search and PageRank The web as a giant searchable database 3 Content and data exploration through Linking to external data sources (e.g. NewsItem on Apple to DBPedia article to filing on sec.gov)‏ Interesting m e shups 2 Inferencing (Apple>Steve Jobs>iPhone) Semantic Browsing Metadata as facets News I want to read (FOAF interest) ‏
  • 7. Bridging the Gap SPARQL, Faceted Browse RDFization, Entity Extraction XSD2OWL, NewsCodes2SKOS IPTC NAR
  • 8. Linking To External Data Sources DBPedia sec.gov data.gov geonames News LOD Cloud Linked Open Data
  • 9. Why RDF? <ul><li>RDF rocks! </li></ul><ul><ul><li>“ Anyone can say anything about anything” </li></ul></ul><ul><ul><li>Labeled directed graph </li></ul></ul><ul><ul><li>Typed (semantic) links </li></ul></ul><ul><ul><li>Cross-domain entity correlation bridges silos (owl:sameAs) </li></ul></ul><ul><ul><li>Inferencing </li></ul></ul><ul><li>RDF myths debunked </li></ul><ul><ul><li>RDF is a data model </li></ul></ul><ul><ul><li>RDF is easy: Subject-Predicate-Object </li></ul></ul><ul><ul><li>Serializations not limited to RDF/XML: N3, Turtle, N-Triples, RDFa </li></ul></ul><ul><ul><li>A layer on top of XML and RDBMS apps </li></ul></ul>

Designing an OWL News Ontology <ul><li>Leverage </li></ul><ul><ul><li>IPTC NAR XML Schemas </li></ul></ul><ul><ul><ul><li>NewsML-G2, EventsML-G2, and SportsML-G2 </li></ul></ul></ul><ul><ul><li>Existing vocabularies </li></ul></ul><ul><ul><ul><li>FOAF (Friend Of A Friend) </li></ul></ul></ul><ul><ul><ul><li>Dublin Core </li></ul></ul></ul><ul><ul><ul><li>Good Relations (e-commerce) </li></ul></ul></ul><ul><ul><ul><li>SIOC (Semantically Interlinked Online Communities) </li></ul></ul></ul><ul><ul><ul><li>etc. </li></ul></ul></ul>
  • 11. RDFization, SKOSification, and Entity Extraction Generate RDF/XML or XHTML+RDFa Use XSLT, XQuery, relational2RDF Named Entity Extraction (Open Calais) SKOSify existing taxonomies Set RDF links to data sources in LOD Automate link generation (Silk) Yahoo Search Monkey Google Rich Snippets RDF crawlers Linked Open Data Cloud
  • 12. Search, Browse, Meshup Search Expose SPARQL endpoint Browse Expose RDF metadata as facets Meshup Limited only by your own imagination
  • 13. Value Added News Global economic Tsunami hits newspapers. Ad revenues decline. Paid content becomes an imperative. After a decade of free content, readers want to know why they have to pay now. SemWeb enriches content. Findability and relevance. Real value for professional audience.
