A minimum effort distributed library for KMi (HackLab Project #3) - PowerPoint PPT Presentation

A minimum effort distributed library for KMi (HackLab Project #3) Tom Heath and Mark Gaved Knowledge Media Institute The Open University, UK ESWC Workshop on Scripting for the Semantic Web

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! Tom Heath and Mark Gaved 2 30/05/2005 ESWC Workshop on Scripting for the Semantic Web

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)" Tom Heath and Mark Gaved 3 30/05/2005 ESWC Workshop on Scripting for the Semantic Web

Tom and Mark go to work on the challenge Tom Heath and Mark Gaved 4 30/05/2005 ESWC Workshop on Scripting for the Semantic Web

• Issues to address – Acquisition – Maintenance – Access/Use • Approaches we rejected – A central database – Endnote libraries on a network share Tom Heath and Mark Gaved 5 30/05/2005 ESWC Workshop on Scripting for the Semantic Web

Our approach • Principles –minimum effort –maximum devolution, maximum reuse • Solution –ISBNs, 3rd party web services, some PHP glue, existing search tools Tom Heath and Mark Gaved 6 30/05/2005 ESWC Workshop on Scripting for the Semantic Web

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… Tom Heath and Mark Gaved 10 30/05/2005 ESWC Workshop on Scripting for the Semantic Web
