Kolloquium "Positional-Slotted Knowledge Integration in the Semantic Web"

Datum: 15.03.2005, 14:00 bis 16:00
Vortragende(r): Harold Boley (University of New Brunswick, Canada)
Ort: Institut für Informatik, Takustr. 9, 14195 Berlin, Grosser Hörsaal der Informatik
Abstract: The positional-slotted Semantic Web language POSL integrates Prolog's positional and F-logic's slotted knowledge representation for facts and rules on the Web, referring to RDFS or OWL classes for order-sorted typing. POSL's presentation syntax is interconvertible with the XML markup of Object-Oriented RuleML. POSL and OO RuleML have been prototyped in the (Java-based) implementation OO jDREW . A recent information integration effort, the New Brunswick Business Knowledge Base, was enabled by POSL. Current work on POSL includes the following. Webizing employs URIs as OIDs in the IETF form of N3 for individuals, relations, slots, and types. Webized atoms further permit RDF descriptions as slotted facts processed by RDF/POSL rules. RDF blank nodes become clause-global, module-local Skolem constants. The POSL design incorporates these notions in an orthogonal manner, which has allowed their independent development.
