Introducing the Linked Data Research Centre

  1. 1. Introducing theLinked Data Research Centre<br />Dr. Michael Hausenblas<br />http://linkeddata.deri.ie<br />
  2. 2. What is it about?<br />a new cluster?<br />a new project?<br />a new stream?<br />a new unit?<br />
  3. 3. What is it about?<br />No<br />
  4. 4. What is it about?<br />actually, it is about …<br />
  5. 5. What is it about?<br />YOU!<br />
  6. 6. What is it about?<br />You ?<br />http://linkeddata.deri.ie/people<br />
  7. 7. Facts & Figures<br />The Linked Data Research Centre (LiDRC) is an effort to bundle activities around linked data<br />Operating horizontal to units, appointed to drive and lead the linked data research and development<br />Launched in June 2009<br />Currently we are<br />11 DERI researcher, and work together with <br />9 international peers<br />

  9. 9. Linked Data Principles*<br /> Use URIs to name things; not only documents, but also people, locations, concepts, etc.<br /> To enable agents (human users and machine agents alike) to look up those names, use HTTP URIs<br /> When someone looks up a URI we provide useful information; with &apos;useful&apos; in the strict sense we usually mean structured data in RDF.<br /> Include links to other URIs allowing agents (machines and humans) to discover more things<br />(*) http://www.w3.org/DesignIssues/LinkedData.html<br />

  18. 18. Link to other entities<br /> typed links<br />==<br />relations between entities<br />and there are many relations one can think of …<br />

  23. 23. Principles applied …<br />Linked data principles, aka ‘RDF over HTTP’ are good, but they need to be applied<br />Linked data principles applied to<br />… open, freely available datasets (in various source formats such as CSV, XML, etc.), such as WikipediaLinking Open Data (LOD)<br />… enterprise data (CRM, XBRL, etc.)Enterprise linked data (eLD)<br />… (news) feeds, sensors, etc.Streamed linked data<br />… and what is about your domain?<br />
  24. 24. Linking Open Data<br />over 100 open data sets, incl. Wikipedia, Geonames, etc., providing over 4.7 billion RDF triples, interlinked by approximately 142 million RDF links<br />24 of XYZ<br />
  25. 25. So, how does it work?<br />The LiDRC operates within so calledResearch Themes<br />
  26. 26. LiDRC’s Research Themes<br />Discovery<br />Application Domains <br />Publishing <br />Streamed Linked Data<br />
  27. 27. LiDRC’s Research Themes<br />Publishing – creation, interlinking and deployment of linked data<br />Discovery – finding and using linked data<br />Application Domains – from specific content domains (software engineering, multimedia, etc.) to linked data driven applications)<br />Streamed Linked Data – researches data stream such as news feeds, microblogging, RFID/sensor data, etc.<br />
  28. 28. Services offered by LiDRC<br />Tutorials and consultancy regarding linked data publishing, consumption and usage<br />
  29. 29. <ul><li> Architecture of the World Wide Semantic Web Task Force

  31. 31. RDFaTask Force
  32. 32. Co-chair the upcoming RDB2RDF Working Group.</li></ul>Services offered by LiDRC<br />Infrastructure – we contribute to the linked data infrastructure in terms of vocabulary contribute to (W3C) standardisation activities<br />Semantically-Interlinked Online Communities<br />Vocabulary of Interlinked Datasets<br />
  33. 33. Services offered by LiDRC<br />Infrastructure – we contribute to the linked data infrastructure in terms of providing tools and libraries<br />any23<br />LDE<br />Neologism<br />
  34. 34. Hot and Emerging Topics<br />Enterprise Linked Data (new research theme, soon)<br />HCLS (new application area, soon)<br />Realising the read-write Web of Data (pushback and RDForms)<br />Linked data enabled microblogging applications<br />Quality, provenance, trust<br />Linked Data-Driven (Web) applications …<br />
  35. 35.
