Profiling and tutoring users in virtual campus

Virtual campus is a research project which aims to provide a comprehensive and innovative e-learning environment for authoring, fruition and tutoring. The paper introduces TVM, the tutoring module developed for virtual campus. TVM tracks the learners´ behavior within the virtual campus environment and defines a user model (based on Bayesian networks) in terms of learning attitudes, efficiency of learning strategies, and attitude to cooperation and communication. Derived information is used to build and make available graphical reports to learners and teachers. Moreover TVM, relying on fuzzy logics, exploits the user model to support learners´ choices making suggestions which take into account the style, the behavior and the results obtained in the past.
