Support educational resource accessibility requirements in a knowledge graph modelling framework

Knowledge modelling techniques based on knowledge graphs can be used in the context of building customized and flexible e-learning systems to provide learning resources that are accessible to anyone, including learners with special needs and accessibility preferences. The paper describes how a personalized educational resource system that considers the needs of learners, especially when it comes to learners with accessibility needs, can benefit from knowledge graph-based technologies used as resource representation formalism. Knowledge graphs can be used to provide learners with suitable learning objects, learning activities, and teaching methods based on their different preferences and needs and to perform domain knowledge reasoning through modelled domain knowledge.
