Clarifying the semantics of relationships between learning objects

Abstract

In this paper we discuss about the ambiguities and deficiencies of the Learning Object Metadata (LOM) standard to specify relationships between learning objects (LOs), specially those relationships that relate LOs instances. We also study the impact of relationships in the internal organizational structure of LOs. As main contribution, we develop a taxonomy of possible relationships between LOs that has been created by refining the LOM standard relationships with other meaningful relationships from a common sense ontology. © 2009 Springer-Verlag Berlin Heidelberg.
