Track Overview

Interesting talks Programming the Semantic Web Steffen Staab (Universität Koblenz-Landau, DE) Programming the Semantic Web “semantic web data is wonderful, but programming them changed too little since 2000 and still is a mess” Outside data management Understanding by developer Triple-object mapping Code generation Process of federation Example: Node Path Query language Store.NPQ(C).”mo:MusicArtist”.Extension

Interesting talks Coordination, Semantics, and Autonomy Semantic Web helps us deal with problems with high degree of coordination complexity Require human-machine communication and coordination Human talk to each other much less than devices "humans: intelligent, free, conscious - machines nowaday: smart, autonomous, self-monitoring" The predictability and manipulability of autonomous choices "the more rational you decide the more predictable you are“ are you still free?
