Research in the area of technology‐enhanced learning (TEL) throughout the last decade
has largely focused on sharing and reusing educational resources and data. This effort has …

Learning objects are systematically organised and classified in online databases, which are
termed learning object repositories (LORs). Currently, a rich variety of LORs is operating …

Personalized adaptive learning requires semantic-based and context-aware systems to
manage the Web knowledge efficiently as well as to achieve semantic interoperability …

Owing to the recent developments in automatic metadata generation and interoperability
between digital repositories, the production of metadata is now vastly surpassing manual …

This paper conducts the first detailed quantitative study of the process of publication of
learning objects in repositories. This process has been often discussed theoretically, but …

This paper develops the concept of relevance in the context of learning object search. It
proposes a set of metrics to estimate the topical, personal and situational relevance …

In this article we present a review of selected literature of context-aware pervasive
computing while integrating theory and practice from various disciplines in order to construct …

Reusing digital resources for learning has been a goal for several decades, driven by
potential time savings and quality enhancements. Although the rapid development of Web …

In traditional e-learning, teachers design sets of Learning Objects (LOs) and organize their
sequencing; the material implementing the LOs could be either built anew or adopted from …

Automatic course generation is a very important area of research with numerous practical
applications in e-learning. It has been studied since the 1980s within the fields of intelligent …
