This research applies ideas from argumentation theory in the context of semantic wikis, aiming to provide support for structured-large scale argumentation between human agents. The implemented prototype is exemplified by modelling the MMR vaccine controversy.

We propose to automatically summarize student responses to reflection prompts and introduce a novel summarization algorithm that differs from traditional methods in several ways. First, since the linguistic units of student inputs range from single words to multiple sentences, our summaries are created from extracted phrases rather than from sentences. Second, the phrase summarization algorithm...

Many Intelligent Tutoring Systems (ITSs) have started to incorporate game-based components in an attempt to improve student engagement during system interactions. iSTART-ME is a new game-based learning environment that was developed on top of an existing ITS (iSTART). Initial investigations focused on individual, isolated components. However, to increase ecological validity, the current study w...

Detachable user interfaces consist of graphical user interfaces whose parts or whole can be detached at run-time from their host, migrated onto another computing platform while carrying out the task, possibly adapted to the new platform and attached to the target platform in a peer-to-peer fashion. Detaching is the property of splitting a part of a UI for transferring it onto another platform. ...
