A recommendation system in a collaborative digital library environment

We envisage a Digital Library not only as an information resource where users may submit queries to satisfy their information need, but also as a collaborative working and meeting space. We will present a personalized collaborative Digital Library environment, where users may organise the information space according to their own subjective view, may become aware of each other, exchange information and knowledge with each other, may build communities and may get recommendations. After formalising the main concepts of the personalized collaborative environment, major emphasis is given to the computational model for recommendation generation.
