Background• Rich resource of Repositories
• Other rich resources (NSF, CORDIS, ResearchIndex, Wikipedia)
• Where is the added value?

Linked Data• Designed for just this
• “the Semantic Web done right, and the Web done right”
• Tim Berners-Lee
• An Infrastructure for Naming things and Linking things
• OR can/should join

RKB and RKBExplorer• RKB (ReSIST Knowledge Base) and RKBExplorer
• Knowledge-enabled infrastructure for cooperation in research into resilient systems
• Came out of CS AKTiveSpace– (Semantic Web Challenge winner 2003)
• Reasonably mature system and ongoing development

Now Look at an Author

Or a Paper
![Page 11: RKBExplorer: Repositories, Linked Data and Research Support](https://reader035.vdocument.in/reader035/viewer/2022062408/568132aa550346895d995297/html5/thumbnails/11.jpg)

Or a Couple of People
And howthey arelinked

12
And Why they are Linked?
![Page 13: RKBExplorer: Repositories, Linked Data and Research Support](https://reader035.vdocument.in/reader035/viewer/2022062408/568132aa550346895d995297/html5/thumbnails/13.jpg)
Who is Carl Lagoze?

Co-Reference• Repositories have people, publications, etc. from other institutions who also have records there and elsewhere
• And vice versa
• Co-Reference is a Big Problem– Everything is a URI (not title, name, number…)– Identifying multiple URIs for one resource– Rejecting incorrectly conflated resources– Publishing– Using
• Coldstart– A serious problem– Nothing is linked to anything– Not even (reliably) within most repositories

Co-Reference Service (CRS)• CRS Subsystem
– Find co-references– Store them– Publish them
•Essentially:•URIi -> { URI1, …, URIi, …, URIn }
– Recommend a “Canon”
• Published by the Data Publisher– And possibly others
• Middleware aggregates co-references from recognised CRSes

Open System• RKBExplorer is only one interface
– And not a required part
• Services:– Details for a paper (the right hand pane in RKBExplorer):• http://www.rkbexplorer.com/detail/?uri=http://southampton.rkbexplorer.com/id/eprint
s-12614
– Network of people for a publication (lower pane):• http://www.rkbexplorer.com/network/?uri=http://southampton.rkbexplorer.com/id/eprin
ts-12614&type=publication-person
– …
• Other Interfaces (using the services)– Personal Web pages– iPhone– iGoogle Gadget

Gadget – find out about people

Update in Action
19
Before and after inserting this paper in the Southampton ePrints repositoryand RKB has noticedNote the position of Les Carr in Hugh’s related People
![Page 20: RKBExplorer: Repositories, Linked Data and Research Support](https://reader035.vdocument.in/reader035/viewer/2022062408/568132aa550346895d995297/html5/thumbnails/20.jpg)
Concluding Remarks• ePrints today, other systems tomorrow
– Other related technologies (such as OAI-ORE)– Are they right for this?
• Please don’t stop at the repository
• Go on and get the added value of Linked Data
• ePrints has plans to publish RDF– Will the schema (ontology) by expressive enough
• Worry about your co-reference– Do you have IDs in your respository?– Can you reliably identify all the papers of a single person?
