The significant growth of media and user-generated content online has allowed for the widespread adoption of recommender systems due to their proven ability to reduce the workload of a user and personalise content. In this paper, we describe our prototype system called Buzzer, which harnesses real-time micro-blogging activity, such as Twitter, as the basis for promoting personalised content, su...

We report on MobiDics, a mobile learning platform for professors, lecturers and tutors. In a survey with 100+ participants, we revealed that young, inexperienced teaching personnel at universities rarely use specific didactic methods to plan and structure courses. Such methods play an important role in learning processes since they, for example, activate students and contribute to more profound...

Education and training are essential elements of co-operative practice embodied within the co-operative principles. A problem common to many types of co-operative is that the level of commitment shown towards education and training can be weak at best, and often diminishes as they become more established and as the size of the membership and scale of operations grow. This leads to many difficul...

Consumers using online auction websites face the challenge of appraising products at a distance. Sellers and buyers in online auctions navigate this challenge by displaying and evaluating various cues, a critical one being use of photographs. Warranting theory predicts that cues less subject to control and manipulation by the presenter will be more influential in impression formation. Therefore...

In this experiment, participants were presented with a prosocial message modeled from modern public health campaigns. Although the message was kept identical, the context of the message was experimentally manipulated to represent either a viral user-generated video or a government-sponsored public service announcement. The data provided evidence of an indirect relationship between media context...

The UGC is encouraging (read mandating) that all Hong Kong universities implement the Outcomes Based Teaching and Learning (OBTL) approach to curriculum design and class teaching as soon as possible. The approach is based on a particular philosophy concerning the educational process, and it involves both rethinking the curriculum as a whole for each academic major and revising the way virtually...

The MediaEval 2012 Genre Tagging Task is a follow-up task of the MediaEval 2011 Genre Tagging Task and the MediaEval 2010 Wild Wild Web Tagging Task to test and evaluate retrieval techniques for video content as it occurs on the Internet, i.e., for semi-professional user generated content that is associated with annotations existing on the Social Web. The task uses the MediaEval 2012 Tagging Ta...

This paper builds upon and extends previous work on multi-modal mood classification (i.e., combining audio and lyrics) by analyzing in-depth those feature types that have shown to provide statistically significant improvements in the classification of individual mood categories. The dataset used in this study comprises 5,296 songs (with lyrics and audio for each) divided into 18 mood categories...

Privacy protection may be defined as replacing the original content in an image region with a (less intrusive) content having modified target appearance information to make it less recognizable by applying a privacy protection technique. Indeed, the development of privacy protection techniques also needs to be complemented with an established objective evaluation method to facilitate their asse...

Tagging learning resources in repositories or web portals offers a way to meaningfully describe these resources. The more tags there are, however, the more difficult it is to find one’s way around the repository, especially when they are user-generated free-text tags. This paper therefore presents a visualisation of tag clusters based on higher-order co-occurrences that allows users of such rep...
