  1. A Tool for DILIGENT Argumentation:Experiences, Requirements and Design Denny Vrandecic,York Sure AIFB Michael Engler British Telecom plc.Research & Venturing

  2. Motivation: Legal Domain • Problem: • New Judges have theoretical knowledge, but little practical knowledge • On Duty: • When they are confronted with situations in which they are not sure what to do • “Disturb” experienced judges with typical questions. • Solution: • Design an intelligent system to help new judges with their typical problems. • Extended FAQ system using Semantic Web technologies • Connect the FAQ system with the exiting jurisprudence. • Search Jurisprudence using Semantic Web technologies.  Building a new ontology

  3. First Approach + Based on 800 competency questions + Questions were clustered + Middle-out strategy – Usage of ontology not considered – Repetitive discussions – Long discussions

  4. Improvements • Usage of DILIGENT • Speedier discussions • Restriction of arguments • Usage of a wiki • Tracking of arguments • Access from geographical dispersed locations

  5. DILIGENT 1. Build 2. Local adaption 3. Analysis 4. Revision 5. Local update

  6. Argumentation ontology defined Based on Case Studies to identify the most effective types of arguments Argument type recognition based on RST Diligent Argumentation Ontology

  7. Improvements, but… • Visualisation in wiki not supported • Lacking tool cooperation • Management of sources harder • Argument classification harder • No tight integration in an ontology editor • No notification • (No voting)

  8. Design of DILIGENT-Tool • Visualisation: Idea sets • Allows exploring alternative modelling • Sources • URIs, e.g. competency questions • Arguments need to be classified • Notification by IM or E-Mail • Voting • Quick way of expressing opinion • Threshold? • Final decision?

  9. Connection to DILIGENT • Supports the steps build, analysis, revision

  29. Conclusion • We found no off-the-shelf solution sufficient • Design for a collaborative ontology engineering tool using DILIGENT using the DILIGENT argumentation model

  30. Future Work • Automatic classification of arguments • Automatic clustering of sources • Agent participation in discussion • Evaluate voting
