  15. 15. Wikipedia defines Linked Data as “a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF.”<br />Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods. <br />The over 200 semantic web datasets <br />currently contains over 25 billion triples <br />of linked data and 400 million RDF links.<br />http://linkeddata.org/<br />14<br />Killer apps with public data - a cloud of opportunity?<br />Graphic by semanticwebcompany@ Flickr, CC BY-NC-SA<br />
  16. 16. DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link other data sets on the Web to Wikipedia data.<br /> The DBpedia knowledge base currently describes more than 2.6 million things, including at least 213,000 persons, 328,000 places, 57,000 music albums, 36,000 films, 20,000 companies. The knowledge base consists of 274 million pieces of information (RDF triples).<br />http://dbpedia.org/<br />DBpedia and all other linked data is searchable with SPARQL<br />http://en.wikipedia.org/wiki/SPARQL<br />15<br />Killer apps with public data - a cloud of opportunity?<br />
