  1. RKBExplorer.com, sameAs.organd dotAC.info Making Linked Data Work Hugh Glaser Chief Architect, Seme Ltd. Ian Millard

  2. What you may get out of this seminar • Fun • Intellectual stimulation • Understanding of your limits of boredom • Understanding of Linked Data • Linked Data Architecture • A source for knowledge about research activities • A source for knowledge about Linked Data identities • Why you would ask me for a sameAs store of your own • Why you would ask me to publish your Linked Data • Some insight into commercial Linked Data

  3. My “Pitch” • Data Integration Technology • Breaking the Silos, both internal and external • Knowledge-Enabled Infrastructure • Businesses need to know what they know

  4. Low Disruption • Can be implemented without changing the existing processes • Lower Cost • Procurement is different, which represents a challenge • Low Risk • Can be developed alongside existing solutions • Flexible • Changes can be made • Robust • Graceful degradation when services or data sources fail • Open Systems • Supplier flexibility

  5. Linked Data Out There

  6. A Web of Data From the Start

  7. A Web of data… A Web of documents…

  8. Linked Data Principles – You Know This The four micro principles of the Semantic Web 1. All entities of interest, such as information resources, real-world objects, and vocabulary terms should be identified by URI references. 2. URI references should be dereferenceable, meaning that an application can look up a URI over the HTTP protocol and retrieve RDF data about the identified resource. 3. Data should be provided using the RDF/XML syntax 4. Data should be interlinked with other data.

  9. The LOD “cloud” Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/

  10. RDF (Resource Description Framework) “Hugh Glaser works for Seme4” <http://southampton.rkbexplorer.com/id/person-00021><http://xmlns.com/foaf/0.1/name> "Hugh Glaser" . <http://southampton.rkbexplorer.com/id/person-00021><http://aktors.org/ontology/portal#works-for> <http://opencorporates.com/id/companies/gb/05146461> . <http://opencorporates.com/id/companies/gb/05146461><http://www.w3.org/2000/01/rdf-schema#label>“Seme4 Ltd.” .

  11. Making Processing “safer” URIs Semantic Web rdfs:label Difficult problem Natural Language

  12. RKBExplorer.com – a person

  13. Or a couple of people And howthey arelinked

  14. And why are they linked?

  15. Semantic Web is not “All or Nothing”

  18. sameAs.org http://imgs.xkcd.com/comics/standards.png

  19. sameAs.org • Co-reference Service for the whole Web of Data • http://sameas.org/ • Over 100M Linked Data URIs (Identifiers) • URIq -> {URI1, URI2, …, URIn} • Manages multiple identifiers without making a new one • Can be enterprise-based - libraries • http://sameas.org/store/kelle

  20. What is Southampton?

  21. Finding Co-reference

  22. Using Your Own Store

  23. RKB Infrastructure • Manage all the Linked Data functions • Provide appropriate services in appropriate formats • Consumable by “normal” systems • This means • Useful – doing useful things • RESTful – easy to access • JSON – easy to process • … • http://www.rkbexplorer.com/services/ • http://www.ecs.soton.ac.uk/people/dder • http://www.dotac.info/explorer/ • http://www.rkbexplorer.com/gadgets/

  24. RKB Services

  25. RKB Services – Getting A Network

  26. RKB Services – Network Results as JSON

  27. RKB Uses Many Sources, including External Range from a few 100 to more than 10,000,000 “facts”
