Abstract

In modern Economies, knowledge management systems (KMSs) applications are gradually adopted from a growing number of enterprises, organizations and governments. As digital content availability is increasing dramatically through centralized of distributed digital libraries operation, a great research interest is developed upon “clever” knowledge retrieval based on each user’s individual preferences. Modern man usually requests to get knowledge under time pressure. In many cases it is not possible to have enough time to evaluate extensively the huge amount of results presented after a “string-based” criteria query to a digital library. Next generation KMSs should be able to eliminate the results of a search query, based on a certain user’s profile. This profile carries information about the level of preexistent knowledge that maybe a user has on a certain knowledge area, the exact scope of its research and the time that he has available in order to exploit the results of this research. In this paper a new generation of KMSs is proposed that are supporting personalized knowledge retrieval. This is achieved through an innovative architecture of enriched knowledge objects for knowledge representation and the development of an expert system for diagnosis and dynamic knowledge composition.
