1 http://www.sekt-project.com A Tool for DILIGENT Argumentation: Experiences, Requirements and Design Michael Engler British Telecom plc. Research & Venturing Denny Vrandecic, York Sure AIFB

2 http://www.sekt-project.com 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 http://www.sekt-project.com First Approach + Based on 800 competency questions + Questions were clustered + Middle-out strategy – Usage of ontology not considered – Repetitive discussions – Long discussions

4 http://www.sekt-project.com Improvements Usage of DILIGENT Speedier discussions Restriction of arguments Usage of a wiki Tracking of arguments Access from geographical dispersed locations

5 http://www.sekt-project.com DILIGENT 1. Build 2. Local adaption 3. Analysis 4. Revision 5. Local update

6 http://www.sekt-project.com Diligent Argumentation Ontology Argumentation ontology defined Based on Case Studies to identify the most effective types of arguments Argument type recognition based on RST

7 http://www.sekt-project.com 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 http://www.sekt-project.com 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 http://www.sekt-project.com Connection to DILIGENT Supports the steps build, analysis, revision

29 http://www.sekt-project.com Conclusion We found no off-the-shelf solution sufficient Design for a collaborative ontology engineering tool using DILIGENT using the DILIGENT argumentation model

30 http://www.sekt-project.com Future Work Automatic classification of arguments Automatic clustering of sources Agent participation in discussion Evaluate voting
