Research in IR puts a strong focus on evaluation, with many past and ongoing evaluation campaigns. However, most evaluations utilize offline experiments with single queries only, while most IR applications are interactive, with multiple queries in a session. Moreover, context (e.g., time, location, access device, task) is rarely considered. Finally, the large variance of search topic difficulty make performance prediction especially hard.
Several types of prediction may be relevant in IR. One case is that we have a system and a collection and we would like to know what happens when we move to a new collection, keeping the same kind of task. In another case, we have a system, a collection, and a kind of task, and we move to a new kind of task. A further case is when collections are fluid, and the task must be supported over changing data.
Current approaches to evaluation mean that predictability can be poor, in particular:
Perhaps the most significant issue is the gap between offline and online evaluation. Correlations between system performance, user behavior, and user satisfaction are not well understood, and offline predictions of changes in user satisfaction continue to be poor because the mapping from metrics to user perceptions and experiences is not well understood.
