Tile "mixed-initiative" system-design rationale is explored in the context of networked discourse, in particular in the context of a collaboration model, called DisNet. The frame-based system allows to make contextual relations explicit, but in typical group-projects users can not be expected to formalize the project-context so that it can be used by agents to participate in a collaboration on a higher level. On the level of sub-tasks simple processes can generate a system-behavior that qualifies for collaborative interaction. To achieve model consistency tile model of interaction and the communication structure used by peers are used to colmnunicate system behavior.
