Technologies are increasingly intertwined with people’s daily lives. Consequently, there is an increasing need to consider the ethical impacts that research and innovation (R&I) processes, both in commercial and non-commercial contexts, bring about. However, current methods that offer tools for practicing ethics in R&I inadequately allow for non-et...

This paper discusses Cross-Site Personalization (CSP) an approach to provide personalized assistance for the user in addressing information needs that span independently hosted websites. This is done by seamlessly personalizing the support offered to each individual user, as they browse across multiple websites, by modeling the user's interactions...

Personalisation on the web is mostly confined to websites of online content providers. The main drawback of this approach is the missing consideration of the users previous cross-site browsing experience resulting in an often fragmented browsing experience. This paper introduces a service driven architecture for user-centric personalisation in onli...

Currently the user's web search is disjoint from the resources which is subsequently browsed. Specifically the related instances of the search are not displayed on the following pages. This lack of continuity between the actual search and the web sites displayed may lead to skimming by the user to identify what is relevant on the pages. This paper...

Personalization techniques offer the possibility to tailor each learner's experience of a Digital Educational Game (DEG) to their specific needs. Such personalizations can adapt the challenge and difficulty of the DEG to the learner's cognitive ability, motivation and gaming abilities. In particular, complex story based DEGs have introduced micro a...

Most Adaptive Hypermedia Systems today focus on providing an adaptive portal or presentation/application through which adaptive retrieved content is delivered. Moreover the content used by such adaptive systems tends to be handcrafted for adaptivity, i.e. from closed corpus repositories. If adaptive hypermedia is to become more mainstream we need t...

End users of Adaptive Hypermedia Systems (AHS) receive an experience that has been tailored towards their specific needs. Several AHS have produced favourable results showing benefits to the user experience [2]. However, the nature of AHS is that they tend to operate across a focused and fixed domain with a single body of content that is known a pr...
