KBJuly 7 2009
Agenda
• Brief presentation of STITCH main achievements
• Demo: annotation suggestion at KB
• The future use of STITCH results in Subject Indexing at the KB
Background: CATCH
• 10 projects• IT research + Cultureel Erfgoed (Cultural Heritage)• Investigating CH problems, producing applications for CH

Semantic interoperability problem
Semantic alignment as a solution
STITCH goal: using SW techniques for CH data
Application: integrated faceted browser

In the background
Homogeneous representation of thesauri: SKOS• Simple Knowledge Organization System
• (open) standard to exchange thesauri on the Semantic Web

STITCH and SKOS
• Participating in the design of the SKOS model• Having SKOS benefit from experience in KB and CH
domain
• A web-service repository of thesauri and alignments

At this stage, you should have (at least) one question…
How to align thesauri?
Answer: many techniques
1. Using labels of conceptss• frog = frog• frog = frogs• frog = grenouille
2. Using extensional information• The objects described with concepts to align• For example, books
Using extensional concept information: example
ScientificCollection
Depot
1.4Mbooks
1Mbooks
GTT Brinkman
250Kbooks
Aligning GTT and Brinkman

…
• Takes into account variability of usage• Can be useful for specific application scenarios
Application scenarios?
• STITCH = IT research embedded at KB
• Pushing research to KB– Converting KB thesauri to open standards (SKOS)– Presentations, publications in KB context
• DEN, Informatie Professional
• Pushing KB applications to research community– CH experience feeding design of standards– KB case used as benchmark for alignment research– Using CH scenarios to deploy and evaluate
alignments
Let's see this…
But before: questions?
Making it work for KB!
