  1. WP3.4 Reasoning with Inconsistency • Milestone 3.4 • D3.4.3: Reasoning with Inconsistency (version 2) . P/PU/Month 36 • PION: a prototype for Processing Inconsistent ONtology. • PION website: http://wasp.cs.vu.nl/sekt/pion • PION package: new release supports Linux. PION (version 1.3.0) for Windows and Linux (released on April 22, 2006) http://sekt.semanticweb.org/

  2. PION: New extensions • We start to work on the semantic relevance approach for PION • Use Google to obtain light-weight semantics for the selection functions • New framework of inconsistency, negation and ontology changes, which are based on the distinction between incoherence(i.e, the existence of unsatisfiable concept) and inconsistency (i.e., no model). http://sekt.semanticweb.org/

  3. SEKT 3.4: Publication • Inconsistencies, Negations and Changes in Ontologies, Proceedings of the 21st National Conference on Artificial Intelligence (AAAI-06), Boston, July, 2006. ( to appear). • Cooperation work with Knowledge Web (H. Wache and J. Pan) and FORTH, Greece (G. Flouris and D. Plexousakis) http://sekt.semanticweb.org/

  4. Integration with SIP • PION pipeline system has been implemented. PION has been integrated with the SEKT initial platform. http://sekt.semanticweb.org/

  5. WP3.5 Multi-Version Reasoning • Milestone 3.5 – Evaluation and Prototype • D3.5.2: Evaluation of Multi-version reasoning (Delayed) • D3.5.3: Prototype of Multi-version reasoning (version 2), M36. • We are working on a new prototype which achieves the scalability, which can deal with more than 2000 versions of ontologies (rdf/rdfs data) on an ordinary PC (528MB memory). http://sekt.semanticweb.org/

  6. Evaluation of MORE • We are working on the evaluation of the prototype MORE with the legal case study data. • VUA / UAB session at 16.15 this afternoon to discuss the data test issue. http://sekt.semanticweb.org/

  7. WP3.6 Inconsistency Diagnosis and Repair • Milestone 3.6 – Software Prototypes • D3.6.3: Inconsistency Diagnosis and Repair V2. P/PU/Month 36 • Task: Given an inconsistent ontology, locate possible sources of inconsistencies and offer the user (a knowledge engineer) to repair them. http://sekt.semanticweb.org/

  8. Prototype of DION/MUPSter • DION/MUPSter are Debuggers of Inconsistent ONtologies, which use the bottom-up/top-down approaches for inconsistency diagnosis by the support of external/internal DL reasoners respectively. http://sekt.semanticweb.org/

  9. Debugger and Ontology Learning • We are using DION to debug inconsistency of ontologies which are obtained from Ontology Learning (Johanna Volker, York Sure, and Peter Haase) http://sekt.semanticweb.org/

  10. Integration with SIP • We will start to work on DION and MUPSter pipeline systems to integrate them with the SEKT initial platform. http://sekt.semanticweb.org/

  11. Integrating with KAON2 • We are going to integrate all of the prototypes (PION, MORE, and DION) with KAON2 via its DIG interface http://sekt.semanticweb.org/
