OWLED 2008: Experiences and Directions - 5th International Workshop

Join us at OWLED 2008 in Karlsruhe, Germany for discussions on logical grounding, standardization of OWL, usability, software infrastructures and more. Explore advances in reasoners, tableau reasoning, and DB optimization techniques. Discover new features and extensions of OWL. Don't miss the opportunity to learn about ontology matching, ontology visualization, and collaborative editing. Next edition: Autumn 2009 in Virginia.

  1. OWLED 2008OWL: Experiences and DirectionsFifth International WorkshopKarlsruhe, GermanyOctober 26-27, 2008co-located with ISWC 2008http://www.webont.org/owled/2008

  2. Main groups of topics • Logical grounding of reasoning • Standardisation of OWL, possible extensions • Usability, patterns… • Software infrastructures • Specific applications

  3. Main topics • Advances in reasoners for OWL • Improved tableau reasoning • Use of DB to optimise DL reasoning (Oracle, Postgress) • Abductive reasoning • Features/extensions/patterns in/for OWL (2 and forth) • „Easy keys“ • Integrity constraints (how to open/close worlds…) • Datatype system for modelling quantities • Probabilistic extension (Pronto) • „May“ axioms (in medicine) • Description Graph extension (modelling „valid settings“ – vs. SysML as OMG standard) • Calculations (via annotation…) • Enrichment for ontology matching and KDD (by UEP) • User side – visualisation and editing • Manchester syntax; SWRL (APIs…) • Pre-processing – pattern-based manipulation (OPPL) • ACE – use of controlled language for authoring OWL, SWRL • Narrative presentations over ontologies • Explanation of reasoning results (laconic…)

  4. Main topics (cont’d) • Infrastructure • Interface for accessing reasoners (OWLlink) • Versioning • Collaborative editing • Lint tool (Pellint) – removing features that increase computational complexity • Translation between different languages (based on ‘heterogeneous algebraic specification language’) • Domain-specific applications • Biomedicine (whole section!) • Legal domain (OWL Judge) • Access control • Genealogy • Product design • Web portal design • Panel discussion: How OWL may fail?

  5. Next edition • Autumn 2009 • Somewhere in Virginia? Looser collocation with ISWC?
