Nasa. SkinForm. Sphere_system. Questions (and Answers) on the Semantic Web. Slides of the presentation held at the Semantic Web Days, on the 7th of October 2005, in Munich, Germany. The event is coordinated by the European Networks of Excellence REWERSE (Reasoning on the Web with Rules and Semantics) and Knowledge Web (Realizing the Semantic Web). Is the Semantic Web AI on the Web? RDF and OWL are relatively simple things (compared to AI, that is…) They offer: a simple way to express and store metadata a way to “structure” and characterize the terms means to make some inference within a restricted framework and that is it!
One goal in SW is to keep things relatively simple and not necessarily seek absolute completeness (the famous 80/20 rule…) Application dependent rules, e.g., the “uncle” relationship: ∀x,z: ((∃y: (y parent x) ∧ (y brother z)) ⇒ (z uncle x)) Fuzzy and/or probabilisitic logic … Isn’t the RDF Model (and RDF/XML) way too complex? (just look at RDF/XML…) RDF/XML was developed in the “prehistory” of XML e.g., even namespaces did not exist! No! Tagsurf. Philosophy of structure - course. "Architecture is the art of creating physical structures to suit social, emotional, religious political structures" "Structures, structures, structures everywhere..... " Matthew Lella, former student in the course "I think the next century will be the century of complexity" Stephen Hawking How big is this grain..? (see at bottom of Course Outline) Students 2002 Course Progress 2002 An investigation into the nature of various forms of structure that will hopefully lead to a better understanding of Order, Disorder, Chaos, Stability, Nature, Human Constructs, Animal Constructs, History and the Future.
