This paper present a new approch to computationally augment the interaction people have in an on-line community to jumpstart the search for common ground.
They distinguish between common knowledge and mutual knowledge. The former is defined as the knowledge that is shared but not known to be shared. The latter is the knowledge that is shared and known to be shared (Krauss & Fussell, 1990).
They define m-cue as artifacts that augment the edge of interpretative community by transforming an existing pattern of common knowledge into mutual knowledge.
