Domains such as multiple trauma management, in which there are multiple interacting goals that change over time, are ones in which plan recognition’s standard inductive bias towards a single explanatory goal is inappropriate. In this paper we define and argue for an alternative bias based on identifying contextually "relevant" goals. We support this claim by showing how a complementary planning system in TraumAID 2.0, a decision-support system for the management of multiple trauma, allows us to define a four-level scale of relevance and therefore, of measurable deviations from relevance. This in turn allows definition of a bias towards relevance in the incremental recognition of physician plans by TraumAID’s critiquing interface, TraumaTIQ.
