1. STITCH final event KB July 7 2009

2. Agenda Brief presentation of STITCH main achievements Demo: annotation suggestion at KB The future use of STITCH results in Subject Indexing at the KB

3. Background: CATCH 10 projects IT research + Cultureel Erfgoed (Cultural Heritage) Investigating CH problems, producing applications for CH

4. The STITCH project Antoine Isaac Lourens van der Meij Shenghui Wang Henk Matthezing, KB Stefan Schlobach, VU Claus Zinn, MPI Paul Doorenbosch, KB Frank van Harmelen, VU Peter Wittenburg, MPI Dirk Kramer Johan Stapel http://stitch.cs.vu.nl/

5. Semantic interoperability problem

6. Semantic alignment as a solution

7. STITCH goal: using SW techniques for CH data

8. Application: integrated faceted browser KB Illuminated manuscripts BNF manuscripts

9. KB: Illuminated manuscripts

10. KB: Iconclass classification

11. BNF: Mandragore collection

12. BNF: Mandragore thesaurus

13. Application: integrated faceted browser

14. Live demo? Cross-lingual multi-collection search

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

16. In the background Semantic alignment of thesauri

17. 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 Repository web service MPI VU

18. Live demo? http://kits.cs.vu.nl:38080/vocreptags/autocompleteplus.jsp http://stitch.cs.vu.nl/repository/

19. At this stage, you should have (at least) one question…

20. 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

21. Using extensional concept information: example Aligning GTT and Brinkman

22. Automatic statistic alignment plankzeilen surfsport GTT Brinkman

23. Extensional alignments BrinkmanGTT SchilderijenSchilderkunst KwaliteitszorgKwaliteitsmanagement NederlandsNederlands taalkunde Beeldende kunstenBeeldende kunst Archeologie ; NederlandOpgravingen … Takes into account variability of usage Can be useful for specific application scenarios

24. 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

25. Let's see this… But before: questions? Making it work for KB!
