At this stage, you should have (at least) one question…
![Page 20: STITCH final event KB July 7 2009. Agenda Brief presentation of STITCH main achievements Demo: annotation suggestion at KB The future use of STITCH results](https://reader035.vdocuments.us/reader035/viewer/2022070307/551b1dba5503462e578b6159/html5/thumbnails/20.jpg)
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
![Page 21: STITCH final event KB July 7 2009. Agenda Brief presentation of STITCH main achievements Demo: annotation suggestion at KB The future use of STITCH results](https://reader035.vdocuments.us/reader035/viewer/2022070307/551b1dba5503462e578b6159/html5/thumbnails/21.jpg)
Using extensional concept information: example

• 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!
