Creating a good quality Adaptive Educational Hypermedia (AEH) system involves a great expenditure of time, effort and money, especially to author the materials in order to implement adaptivity. Moreover, authoring AEH systems is as hard as maintaining them. Furthermore, with the new advances in AEH development, the authored content in a given system can(More)
Adaptive Educational Hypermedia (AEH) is very time consuming and complex to produce. Moreover, with the rapid rate of AEH development, content generated within a given system can become outdated very rapidly. Both of these contribute to the slow uptake of AEH outside of the research community. We consider interoperability between AEH systems to be an(More)
In this paper, we investigate whether semantic relationships between entities can be learnt from analyzing microblog posts published on Twitter. We identify semantic links between persons, products, events and other entities. We develop a relation discovery framework that allows for the detection of typed relations that moreover may have temporal dynamics.(More)
