Functional and multivalued dependencies in nested databases generated by record and list constructor
tor. In order to capture different data models at a time, an abstract algebraic approach based on nested attributes is taken. The presence of the list constructor calls for a new i...

On Keys and Functional Dependencies as First-Class Citizens in Description Logics
We investigate whether identification constraints such as keys and functional dependencies can be granted full status as a concept constructor in a Boolean-complete description log...

Learning Functional Dependency Networks Based on Genetic Programming
Bayesian Network (BN) is a powerful network model, which represents a set of variables in the domain and provides the probabilistic relationships among them. But BN can handle dis...
