==Evaluating a consultation case: tax credits==
In the afternoon of 17 May, Aldo de Moor presented some of his work on GRASS, and his current research approach to this area: developing techniques to create ontologies that model the actors, workflows and events in discussions.

After his talk was over, we tried applying his approach to a tax credit consultation that AdviceNI recently completed. They had asked advice workers in independent advice centres across Northern Ireland to take part in a discussion on the problems families were having when they had received an overpayment of family tax credit from the Inland Revenue, and suddenly had to pay it back. The advice workers then brought in people from families affected by the problem to describe their experiences in the online discussion forum.

de Moor and Klerks' model has 4 levels, collaboration (including the goals), authoring (what objects are produced), support (for discussion) and discussion.

===Collaboration===
*'''Actor'''
**Families
**Citizens
**Agencies
