Research Areas

Research Interests

My research focuses on the management of data and knowledge in business environments. My early research centered on the representation of uncertainty, and reasoning under uncertainty, for decision making in automated and semi-automated environments. This included, in the context of databases, the representation of uncertainty in relational databases using probability calculus and reasoning mechanisms to deal with such uncertainty in the data. In the context of knowledge-based systems, I have worked on efficient representations of uncertainty (again using probability measures), as well as learning knowledge-based structures from data. That work has led to several research streams. In one stream, I examine the impact of information quality on decision making, developing mechanisms to estimate the quality of information derived from imperfect data. Another stream looks at ways to reconcile information originating from diverse imperfect data sources. A third stream looks at ways to minimize data privacy concerns that arise when organizations share data with each other. More recently, I have been working in the area of personalization, studying how patterns of user behavior can be used to learn customer profiles and to improve recommendations in online commerce. Another area of research examines software release policies.
