Problem scenario: Tom couldn’t find a book…

“Does anyone have a copy of ‘Readings in Nonmonotonic Reasoning’?”

Question: how can we find out who has a particular book on their shelf in KMi? Answer: we need a system!

John’s Champagne challenge

"So Tom, if you manage to set up a running system (technology + people) which captures over 50% of what is on the shelves in KMi and maintains this for at least 3 months I'll buy you a bottle of

champagne (or equivalent other alcohol)"

Issues to address

– Acquisition – Maintenance – Access/Use

Approaches we

rejected

– A central database – Endnote libraries on a network share

Our approach

Principles

–minimum effort –maximum devolution, maximum reuse

Solution

–ISBNs, 3rd party web services, some PHP glue, existing search tools

Some more semantics please…

Next steps

– Transform XML output to RDF/XML on the fly – Make person-to-book link machine readable – Some technical bits (caching, error handling..)

Result

– Nice big SW data set to play with! – Integrate with the KMi Semantic Portal

Other applications

– placename-to-lat/long resolution, email-to- mbox_sha1sum…
