Towards the Linked Data Web, Sören Auer, 26.1.2011, Brussels, Belgium

  1. 1. Towards the Linked Data Web Sören Auer<br />
  2. 2. Problem: Try to search for these things on the current Web:<br />Apartments near German-Russian bilingual childcare in Leipzig.<br />ERP service providers with offices in Vienna and London.<br />Researchers working on multimedia topics in Eastern Europe.<br />Informationis available on the Web, but opaque to current Web search.<br />Why Linked Open Data?<br />Solution: complement text on Web pages with structured linked open data & intelligently combine/integrate such structured information from different sources:<br />Search engine<br />HTML<br />HTML<br />RDF<br />RDF<br />Web server<br />Web server<br />Web server<br />Web server<br /><br />Has everything about childcare in Berlin.<br /><br />Knows all about real estate offers in Germany<br />DB<br />DB<br />

  4. 4. LOD achievements and challenges<br /><ul><li>Web - a global, distributed platform for data, information and knowledge integration
  5. 5. exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF (W3C Standards)</li></ul>Achievements<br />Extension of the Web with a data commons (25B facts<br />vibrant, global RTD community<br />Industrial uptake begins (e.g. BBC, Thomson Reuters, Eli Lilly) <br />Emerging governmental adoption in sight<br />Establishing Linked Data as a deployment path for the Semantic Web.<br /><ul><li>Challenges</li></ul>Coherence: Relatively few, expensively maintained links<br />Quality: partly low quality data and inconsistencies<br />Performance: Still substantial penalties comparedto relational <br />Data consumption: large-scale processing, schema mapping and data fusion still in its infancy<br />Usability: Missing direct end-user tools and network effect<br />These issues are closely related and should ultimately lead to an ecosystem of interlinked knowledge!<br />April 2008<br />July 2007<br />September 2008<br />July 2009<br />

Some Benefits of Linked Open Gov’t Data<br />Enables applications that allow for<br />getting a 360 ° view on an issue<br />rapid fact-checking<br />cross-referencing and checking of statistical claims (“how to lie with statistics”)<br />increased transparency in public debate<br />release of the creative potential of “the crowd” <br />Help citizens in their daily life<br />to understand their governments better<br />find good places to live (little pollution, good schools, close to protected natural sites…)<br />locate public services (administrative offices, public toilets…)<br />Brings citizens and government closer together<br />
