abstract

  • This paper describes the conceptual framework OntoGlue for the assembly of learning objects (LOs). To permit a coherent assembling process from the point of view of requirements and competencies, OntoGlue enhances the definition of LOs by including associated knowledge (i.e. requirements and competencies) in their conceptual data schema.
    This associated knowledge is defined in terms of classes
    of educational ontologies (used as taxonomies), possibly
    related by mappings. There are several advantages associated with
    the OntoGlue approach. Firstly, it provides an enhanced
    description of the LOs, which permits their search and reuse by
    considering
    requirements and competencies. Secondly, during the assembly
    process of two LOs, OntoGlue checks that the competencies of
    the first LO cover the requirements of the second LO,
    guaranteeing a coherent assembling process from the requirements and
    competencies' point of view. Thirdly, OntoGlue automatically
    calculates the meta-data of the resulting assembled LO. Finally,
    the definition of the associated knowledge in terms of
    classes of ontologies, possibly related by mappings, permits an advanced
    comparison of requirements and competencies during assembly and search processes.
