Insights and Future Directions from the 2008 OWLED Workshop on OWL Reasoning and Applications

The Fifth International Workshop on OWL Experiences and Directions (OWLED) took place in Karlsruhe, Germany, on October 26-27, 2008. Co-located with ISWC 2008, the workshop gathered experts to explore key topics including logical grounding of reasoning, OWL standardization, usability, and software infrastructures for OWL applications. Participants discussed advances in reasoning technology, specific applications in biomedicine and law, and challenges in ontology management. The event aimed to foster collaboration and innovation in the use of OWL.

  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?
