In this article, we introduce a comprehensive framework supporting a privacy-aware access control mechanism, that is, a mechanism tailored to enforce access control to data containing personally identifiable information and, as such, privacy sensitive. The key component of the framework is a...

This work is an initial exploration of the use of the decision-theoretic concept of utility to guide pattern mining. We present the use of utility functions as against thresholds and constraints as the mechanism to express user preferences and formulate several pattern mining problems that use...

Public sector planning and management problems are challenging and complex. Specifically, decision makers (DMs) responsible for environmental control, policy and management problems are faced with a vast array of alternatives from which one must be identified for implementation. In addition to...
