Nowadays, various innovative air combat paradigms that rely on unmanned aerial vehicles
(UAVs), ie, UAV swarm and UAV-manned aircraft cooperation, have received great attention …

This book presents the advancements and applications of neutrosophics, which are
generalizations of fuzzy logic, fuzzy set, and imprecise probability. The neutrosophic logic …

The paper considers the problem of merging several belief bases in the presence of integrity
constraints and proposes a logical characterization of operators having a majority behaviour …

This text sets out a series of approaches to the analysis and synthesis of the World Wide
Web, and other web-like information structures. A comprehensive set of research questions …

Query processing and optimization in mediator systems that access distributed non-
proprietary sources pose many novel problems. Cost-based query optimization is hard …

In this paper, we address the problem of managing inconsistent databases, ie, databases
violating integrity constraints. We propose a general logic framework for computing repairs …

A relational database is inconsistent if it does not satisfy a given set of integrity constraints.
Nevertheless, it is likely that most of the data in it is consistent with the constraints. In this …

Knowledge-based systems must be able to" intelligently" manage a large amount of
information coming from different sources and at different moments in time. Intelligent …

The problem of integrating information from conflicting sources comes up in many current
applications, such as cooperative information systems, heterogeneous databases, and …

Many challenging problems in information systems engineering involve the manipulation of
complex metadata artifacts or models, such as database schema, interface specifications, or …
