This volume presents recent research, challenging problems and solutionsin Intelligent Systems- covering the following disciplines: artificial andcomputational intelligence, fuzzy logic and other non-classic logics,intelligent database systems, information retrieval, information fusion,intelligent search (engines), data mining, cluster analysis, unsupervisedlearning, machine learning, intelligent data analysis, (group) decision supportsystems, intelligent agents and multi-agent systems, knowledge-based systems,imprecision and uncertainty handling, electronic commerce, distributed systems,etc. The book defines a common ground for sometimes seemingly disparateproblems and addresses them by using the paradigm of broadly perceived intelligentsystems. It presents a broad panorama of a multitude of theoretical andpractical problems which have been successfully dealt with using the paradigmof intelligent computing.
