This paper investigates to what extent task-oriented user support based on plan recognition is feasible in a highly situation-driven domain like information retrieval (IR) and discusses requirements for appropriate task models. It argues that information seeking tasks which are embedded in some higher-level external task context (e.g. travel planning) often exhibit procedural dependences; that these dependences are mainly due to external task; and that they can be exploited for inferring the users' goals and plans. While there is a clear need for task models in IR to account for situational determinants of user behaviour, what is required are hybrid models that take account of both is “planned” and “situated” aspects. Empirical evidence for the points made is reported from a probabilistic analysis of retrieval sessions with a fact database and from experience with plan-based and state-based methods for user support in an experimental travel planning system
