The document discusses how linking data and using semantic technologies can make applications and machines smarter. It provides examples of how linked data is being used by organizations like the BBC, Ordnance Survey, and Foursquare. It also outlines some barriers to wider adoption of linked data like business models, licensing, scalability, and privacy.

29. Geographic Information on the Semantic Web – an example © Semantic Web Company – http://www.semantic-web.at/ “ We are investing in semantic technology research to cut the cost and improve the accuracy of data integration. ” http://www.ordnancesurvey.co.uk/oswebsite/opendata/ Ordnance Survey (OS) is Great Britain's national mapping agency, providing the most accurate and up-to-date geographic data, relied on by government, business and individuals.

31. Semi-automatic integration of data © Semantic Web Company – http://www.semantic-web.at/ … and we can begin to use ontologies to provide bridges between these different world views. As techniques for ontology merging, and ontology to database mapping are developed, it will become easier to semi-automatically integrate our data with our customers'. http://www.ordnancesurvey.co.uk/oswebsite/partnerships/research/research/semantic.html

32. Example mashups with data from OS & data.gov.uk © Semantic Web Company – http://www.semantic-web.at/ Pharmacy coverage over England http://server-2.webcoding.co.uk/OpenData/

33. Use OS data together with OpenStreetMap © Semantic Web Company – http://www.semantic-web.at/ From: http://www.freeourdata.org.uk/blog/

34. Data repurposing: Separating data model from application logic © Semantic Web Company – http://www.semantic-web.at/ Another benefit of semantic technology is that of data repurposing . Our customers have their own terminology for the things they use day to day: and they may not be the same words that Ordnance Survey uses. http://www.ordnancesurvey.co.uk/oswebsite/partnerships/research/research/semantic.html

35. Data repurposing: Separating data model from application logic © Semantic Web Company – http://www.semantic-web.at/ There are also internal business advantages for Ordnance Survey: with an explicit, machine readable description of the meaning of our data, we can improve quality control and classification decision-making. http://www.ordnancesurvey.co.uk/oswebsite/partnerships/research/research/semantic.html

36. Example: OS´s Buildings and Places ontology © Semantic Web Company – http://www.semantic-web.at/ Ordnance Survey uses complex class axioms expressed via OWL to being able to categorize spatial things. See: http://www.ordnancesurvey.co.uk/oswebsite/ontology/

41. Example: linkedgeodata.org © Semantic Web Company – http://www.semantic-web.at/ LinkedGeoData uses the information collected by the OpenStreetMap project and makes it available as an RDF knowledge base according to the Linked Data principles. It interlinks this data with other knowledge bases in the Linking Open Data initiative
