An educational-oriented approach for building personalised e-learning environments that focuses on putting the learners' needs in the centre of the development process is provided.
Affective issues in Semantic Educational Recommender Systems
TLDR
The benefits of considering affective issues in educational recommender systems are discussed and the extension of the Semantic Educational Recommender Systems (SERS) approach, which is characterized by its interoperability with e-learning services, to deal with learners’ affective traits in educational scenarios is described.
Modeling recommendations for the educational domain
TLDR
A semantic recommendations model is defined that can be used to describe the recommendations for technology enhanced learning that should be guided by educational objectives, and not only by the users’ preferences.
