An intelligent virtual environment for distance learning

This paper presents an intelligent, adaptive, three-dimensional and virtual environment for distance learning. The environment, used to make educational content available, has its structure and presentation customized according to users' interests and preferences (represented in user models) and in accordance with insertion or removal of contents. An automatic categorization process is applied in the creation of content models, used in the spatial organization of the contents in the environment. Moreover, the environment is populated by an intelligent agent, who assists users during the navigation and retrieval of relevant information.
