Abstract

This work presents the OCtoPUS model which uses the user behavior information, characterized by trails in a ubiquitous environment, to identify the user profile. The model uses semantic web technologies to represent and infer knowledge about the user, specially the classification inference. A prototype was developed to evaluate the OCtoPUS model in the learning field. The prototype classifies the user in terms of abilities and competencies based on which trails the user have enacted during the course.
