Modelo para la recomendación y recuperación de objetos de aprendizaje en entornos virtuales de enseñanza/aprendizaje

This paper presents a recommendation and retrieval model of learning objects as a complement to intelligent tutoring system, in order to increase the interaction both the teacher and students with the courses in which they are enrolled. To perform a recommendation of learning objects to the teacher the proposed model is founded in the subjects within that teacher develops its courses, whereas for students on the characteristics of the profiles they have. In both cases, a relationship with metadata is established about the learning objects that exist in a constantly updated repository. Thus, this work represents a contribution to the development of efficient and complementary virtual courses, which are also consistent with the needs of their users.
