There should be a computational model around the PhD topic. This is a fundamental requisite for doing the doctorate at EPFL. There may be different directions in which this can happen:

1. cognitive modeling (building an agent) [obsolete because of distributed cognition]
– modeling interaction
– modeling cognition

2. types of interaction when you build a map together?

3. Simulation of human interaction

4. Ontology (ContextML): formal ontology for describing a context. -> relation between the context and the message.

5. Model of argumentation in map editing -> if you where to define the map editing as a game what would be the rules??
