10. Summary


1. Introduction

– 50 students & 5 invited speaker & 8 tutors

all international semantic web experts

– 6 days in in Cercedill (Spain) middle of nowhere

– presentations, tutorials, hands on sessions, poster competition, mini projects, socializing

most intensive learning experience (no place to hide!)


2. SSSW09 - Meeting the “big guys”

Stephan Decker (Head of DERI)

Jérôme Euzenat

Asun Gomez-Perez (Madrid) Enrico Motta (The Open University, UK)

Sean Bechhofer (Manchester, UK)


2. SSSW09 - Poster Competition Interactive Poster

need to bring a poster

Information Part

Interactive Part

2. Place in Best Poster Competition(50 participants)


2. SSSW09 - Mini project

time consuming but perfect for socializing & deep thoughts

– Who: 4-5 people

– What: predefined task covering linked data, matching, modeling

e.g. “holidays from hell”

– How: 1 dedicated tutors + 10 hours + evenings

– Result:

• group presentation

• 2 minute video


2. SSSW09 - Mini project Evaluation of Watson

Ontology Reuse


2. SSSW09 - Socializing a lot of fun …


3. What is the Semantic Web (Stefan Decker & Mark Greaves)

– Google property: will it be better if it gets bigger

more semantic information but messy, inconsistent

complexity vs. benefit - which sees everyone

– Semantic web is always changing

• 144k/day edits in Wikipedia

• 288k/day in del.ici.us

• 388k/day pictures in flickr

• 1.6Millon/day blog entries


4. Application of the Semantic Web
