The document summarizes the Seventh Summer School on Ontological Engineering and the Semantic Web (SSSW'09). It discusses that the summer school had 50 students and 13 instructors who spent 6 days learning about the semantic web through presentations, tutorials, hands-on projects, and social activities. Key topics covered included the application of semantic web technologies, ontology matching, reasoning, ontology engineering, and ontology reuse. Attendees learned about various semantic web tools, projects, and had opportunities to network with international experts in the field. The summary concludes by recommending the summer school as a way to learn about and apply semantic web concepts.

3. 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!)

6. 2. SSSW09 - Mini project
– 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
 time consuming but perfect for socializing & deep thoughts

9. 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
