Uncertainty in Intelligent Databases,By an . we mean a traditional relational database with additional functionalities to represent either (1) general rules, as in deductive databases, or (2) some kind of incomplete information, like marked null values or disjunctive facts, or (3) additional meta-information, like information validity, uncertainty factors, or some kind of modality.

Knowledge Discovery and Acquisition from Imperfect Information,This chapter discusses the issues of imperfect information in the fields of knowledge discovery in databases (KDD) and knowledge acquisition for expert systems (KA) . My perspective on these issues is more of a practitioner motivated by pressing application needs and less of the researcher motivated by the desire to push the frontiers of science.

Probabilistic and Bayesian Representations of Uncertainty in Information Systems: A Pragmatic Introle minimizing the effort? There are a variety of reasons to represent uncertainty and a variety of probabilistic and Bayesian ways to do so, requiring varying amounts of effort. We discuss an approach to resolve these issues, so that the costs will be commensurate with the benefits.

An Introduction to the Fuzzy Set and Possibility Theory-Based Treatment of Flexible Queries and Uncword or a phrase whose meaning is vague or even entirely unclear. As another example, a query may reflect a user’s uncertainty about what he is looking for. In addition, one may want to use vague predicates in a query to express pbl]References among the admissible answers.
