Abstract

Adaptive educational hypermedia necessitate semantic description of a domain, which is used by an adaptive engine to perform adaptation to a learner. The bottleneck of adaptive hypermedia is manual authoring of such semantic description performed by a domain expert mainly due to the amount of descriptions to be created. In this paper we present a method for automated discovery of is-a relationship, one of the most important relationships of conceptual structures. The method leverages specifics of educational content. The evaluation shows reasonable accuracy of discovered relationships reflecting in reduced domain expert’s efforts in domain model creation.
