, thus benefiting users with more personalized and contextual results. This work explores the synergy between recommender systems and context-aware computing, describing the development of COReS (Context-aware, Ontology-based Recommender system for Service recommendation). This recommender system

and flexibility requirements, this platform has been developed through ontology-based context-aware computing and a service oriented approach. We also provide some preliminary results of performance analysis and user survey activity.

Abstract. In this paper, we propose the situation-awareness model for HKMP(Higher order Knowledge Management Platform) that has a capability to offer context-aware personalized services to user. HKMP is a platform that provides the higher order knowledge from the contextual information

Abstract: Online learning initia-tives over the past decade have become increasingly comprehen-sive in their selection of courses and sophisticated in their presen-tation, culminating in the recent announcement of a number of consortium and startup activities that promise to make a university

and the demonstrated usefulness of ontologies and semantic web technologies, the available platforms for managing archetypes do not exploit them. In this paper we present our archetype management system, which enables the semantic management of archetypes, performing a series of activities based on their OWL
