Abstract
This paper presents an in-depth analysis of the semantic web contribution towards personalisation in e-learning content exploitation. The aim of this research work is to develop a framework for analysing the semantic web and ontological issues related with the design and implementation of high performance e-learning systems enabled by advanced semantic web and ontological engineering. Within this context the concept of personalisation is linked to the state of the art of semantic web and ontologies research. The main emphasis is paid to the management of personal profiles and identities. Real learning experiences are promoted through the definition of value-adding layers within semantic e-learning portals.
