On Reliability and Security in Knowledge Grids

Proper knowledge management and advanced semantic reasoning are of pivotal importance in promoting innovation and productivity in a cooperative team and opening new opportunities in commerce, science, and computing applications. To address such a requirements a series of solutions for distributed knowledge management have been proposed over the last decade, among which the most promising is the so-called knowledge grid. Such infrastructures have been traditionally designed for science and educational applications, but they are starting to be progressively used in more critical scenarios, such as disaster management and recovery, or financial services. This imposes the need of providing reliability and security within the context of knowledge grids. The goal of this paper is to define such needs and to describe the correspondence of the available solutions to these needs. Last, we highlight possible space for research opportunities within the topics of reliability and security in knowledge grids.
