In collaborative environments where multiple users interact, determining individual problem-solving contexts that include intent is difficult, even when individual user goals are known. Although intent may be explicit in a sub-context, often it is implicit and must be inferred. Moreover for both implicit and explicit intent or goals, actions to achieve such goals may interact negatively between users. This paper discusses two approaches to determining user and team intent and interactions. We look at a collaborative system that encourages user-specification of goals so that the system can track them, and we look at a keyhole plan recognition approach that infers user intent from individual user action. We enumerate some of the problems with both approaches.
