In this paper we present a generalized description of the Grover operator, employed in a quantum database search algorithm. We will discuss the relation between the original and ge...
Answering queries posed over knowledge bases is a central problem in knowledge representation and database theory. In databases, query containment is one of the important query op...
Repositories of multimedia objects having multiple types of attributes e.g., image, text are becoming increasingly common. A selection on these attributes will typically produce n...
