Creating Topic Maps Ontologies for Space Experiments David Damen TMRA 2009, Leipzig, Germany
ULISSE • European FP7 project • “Improve the exploitation of results from space experiments”
E-USOC Data Providers
Why Topic Maps? • Large variety in background knowledge • More natural expression of knowledge
Ontology Creation - Original Analysis Startup Drafting Interaction Design Verification End-user
Ontology Creation - Adaptations Analysis Startup Drafting Interaction Design Verification End-user
Ontology Creation - ULISSE Preparation Analysis Draft Refinement Ontology Workshops • Iteration 1 • Iteration 2
Ontology Workshops • 9 Ontology Workshops • 27 scientists and engineers involved
Ontology Workshops • Day 1: • Present Topic Maps • Learn about the domain • Day 2: • Dump domain knowledge • Day 3: • Structure domain knowledge
Know Your Stuff • You are the expert • Be prepared for tricky questions
Sell Topic Maps • Do not assume: • Prior knowledge • Willing acceptance
Know Your Audience • Your domain experts: • Scientists? • Software Engineers? • Electrical Engineers? • Business people? • …?
Be a facilitator • Use domain examples: • Make it easier to follow • Show domain understanding • Let them talk • Use tools they already know
Gradually introduce Topic Maps concepts • Do not try to push everything from the start • Try to remember your first encounters with Topic Maps
It’s ok to be scared or nervous • Trust your preparations • Trust yourself • Be prepared to be wrong
Domain experts are nervous too • Probably more than you, but not at first • How well do they know their domain?
Results – General Space Experiments Experiment project educational • Status should be a closed list. The following statuses are proposed: • selected • scheduled - under implementation • launched • active • analysis • completed status acronym report producer produces product Experiment output project encountered event Experiment Anomaly project plans protocol Experiment protocol protocol defines setup Experiment setup Time Interval whole consists-of part Experiment run project imposes constraint Boundary/Limitation condition
Conclusions • Transfer Topic Maps throughout the consortium • Using simple tools raised the involvement • Managing the ontologies across tools is hard
Future Work • Ontologies as TMCL • Incorporate the ontology creation workflow in ScienceCast
