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

…

• 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!
