Intelligent knowledge-based models and methodologies for complex information systems

Complex information systems require more and more advanced knowledge representation, management, and discovery tools and techniques, which converge in a collection of intelligent knowledge-based models and methodologies of emerging interest to research communities. This poses new challenges on the issue of devising innovative methodologies and paradigms in the context of a broad framework encompassing several research topics ranging from knowledge representation to knowledge integration, from knowledge management to knowledge processing, from knowledge discovery to knowledge delivery, and from knowledge security to privacy preserving knowledge. From these challenges, a novel class of complex intelligent information systems raises, where knowledge representation, management, and discovery are emphasized in order to achieve complex functionalities going far beyond those of traditional information-oriented methodologies. Intelligent knowledge-based models and methodologies arise in many
