Cooperative Information Systems provide approximate answers when exact answers are unavailable and provide summary answers when answer sets are too large. Yet without an explanation of how and why such answers were derived, it is hard to estimate their usefulness. Further, the timing and level of detail of such explanations should be user and context dependent. In this paper, we present the architecture, representation, and process of an explanation system which provides such explanations of approximate answers. This explanation system has been implemented and integrated into the Cooperative Information System CoBase (UCLA) for a transportation planning and an electronic warfare domain. Our experience reveals that explanation generation is efficient and receives positive feedback from users.
