The problem of aggregating individual rankings to create an overall consensus ranking representative of the group is of longstanding interest in group decision making. The problem arises in situations where a group of k Decision Makers (DMs) are asked to rank order n alternatives. The question...

Entity-relationship (ER) modeling is a widely accepted technique for conceptual database design. However, the complexities inherent in large ER diagrams have restricted the effectiveness of their use in practice. It is often difficult for end-users, or even for well-trained database engineers...

This paper presents an algorithm to cluster the entities and relationships identified by database designers into a set of internally cohesive subsystems. Our algorithm is based on the calculation of a distance score that is inversely related to the similarity of interactions of a pair of...
