Peer reviewedWong, S. K. M.; Butz, C. J.; Xiang, Y. – Journal of the American Society for Information Science, 1998
Describes a bottom-up procedure for discovering multivalued dependencies in observed data without knowing a priori the relationships among the attributes. The proposed algorithm is an application of technique designed for learning conditional independencies in probabilistic reasoning; a prototype system for automated database schema design has…
