Linked Data Workshop at I-Semantics 2010
1 like493 views
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.

- 28. Locations as an important integration hub on the linked data web Due to the uncoupling of data from its original creation context, semantic interoperability, identity resolution, and ontologies are central methodologies to ensure consistency and meaningful results in a Linked Data Web Space and time are fundamental ordering relations to structure such data and provide an implicit context for their interpretation. Prominent geo-related Linked Data hubs include Geonames.org as well as the Linked Geo Data project which provides a RDF serialization of Open Street Map © Semantic Web Company – http://www.semantic-web.at/
- 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.

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

- 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
