Conclusions & Future work

  • AccessibleOCW ontology was proposed to address the accessibility need of an OCW.
  • A Learner profile was created a a proof of concept
  • Future work
    1. Integrating further accessibility guidelines and techniques into the ontology (i.e., users with cognitive disabilities)
    2. Working on the personalization module to adapt the content presentation according to the learners’ needs.
Ontology-based Representation of Learner Profiles for Accessible OpenCourseWare Systems

Speaker notes:

we presented an ontology that addresses accessibility in OCW systems. We reused and extended the ACCESSIBLE ontology to represent learner needs and preferences with respect to the accessibility requirements of the IMS AfA specifications. IMS AfA is concerned with annotating digital resources and learner preferences to achieve a better accessibility. Combining it with the ACCESSIBLE ontology makes it more extendable and does not limit it to special types of disabilities. The combination of IMS AfA and the ACCESSIBLE ontology provides more detailed descriptions of disabilities, assistive technologies, and user preferences. Furthermore, it allows to add concepts of other disabilities, such as cognitive impairments, which are relevant in learning contexts, and suggests mappings to educational resources.
