PERSONALIZATION , COLLABORATION , AND RECOMMENDATION IN THE DIGITAL LIBRARY ENVIRONMENT CYCLADES

CYCLADES is a system, which combines several technologies from the Information Retrieval and Digital Library area, where users and user communities may deal with a quite large set of heterogeneous digital archives. CYCLADES provides a highly personalized environment where not only users may organize (and search into) the information space according to their individual taste and use, but, and more importantly, also provides advanced features of collaborative work among the users. It is up then to the system to discover interesting properties about the users' interests, relationship between users and user communities, as well as meaningful events that happen in user shared workspaces, and finally to notify the involved users according to their own preferences.
