Design aspects of discovery systems

This paper reviews design aspects of computational discovery systems throug h the analysis of some successful discovery systems. We first review the co ncept of viewscope/view on data which provides an interpretation of raw dat a in a specific domain. Then we relate this concept to the KDD process desc ribed by Fayyad et al. (1996) and the developer's role in computational dis covery due to Langley (1998). We emphasize that integration of human expert s and discovery systems is a crucial problem in designing discovery systems and claim together with the analysis of discovery systems that the concept of viewscopc/view gives a way for approaching this problem.
