The day star­ted nicely with the “Towards a Social Web?!” talk by Stephan Bau­mann—which dis­cussed from FOAF, user mod­els vs. con­texts, tag­ging to social net­works ana­lysis and visu­al­isa­tion, and related work at CHI2007.

Then we got in Twin Peaks mode, where Sean Bech­hofer told us — well, with dif­fer­ent words — what The Giant told Agent Cooper: “The OWLs are not what they seem!”

Fur­ther, Aldo Gangemi dis­cussed about con­cep­tu­al­isa­tion and mod­el­ling aspects in onto­logy design, and presen­ted some onto­logy pat­terns from NeOnDeliv­er­able D5.1.1 — NeOn Mod­el­ling Com­pon­ents.

In the after­noon we had a hands-​on Twin Peaks ses­sion and some modelling/​ontology pat­terns exer­cises; then the first poster ses­sion, where I almost lost my voice explain­ing for two hours my poster about semantic brows­ing with Power­Mag­pie.
