The use of video and audio features for automated annotation of audio-visual data is becoming widespread. A major limitation of many of the current methods is that the stored indexing features are too low-level — they relate directly to properties of the data. In this work we apply a further stage of processing that associates the feature measurements with real-world objects or events. The outp...

Model management tools contain common aspects that are frequently reinvented for each tool. Platform specific solutions to common problems may vary by language, however, the high-level specifications should be the same. Design patterns seek to communicate these common specifications in an abstract way that enables reuse, improves understanding and eases communication. In this paper, we present ...

You probably think of nineteenth century Great Britain as a place without any substantial social safety net aside from the Church. In fact, England had a well-developed welfare system in the nineteenth century, with local government functionaries dispensing cash. Early in the nineteenth century, low-level British functionaries knew almost all the people who were coming before them to appeal for...

A new approach for bridging over the semantic gap is presented. This approach is based solely on the extraction of low-level illumination features, and by using well defined film rules regarding scene lighting, it generates high level semantic descriptors for scenes. These illumination descriptors could be further combined with other descriptors like motion and shot tempo, to generate a more co...

Introduction With the gradual promotion and implementation of China’s national innovation-oriented strategy, research universities are playing an irreplaceable role in leading scientific development and technological innovation. Scientific research is one of the basic functions of a research university, which cultivates high-quality innovations and supports research universities in serving thei...

The UK Worshipful Company of Information Technologists organised two high-level colloquia to debate ethical & spiritual implication of the new IT & Telecoms Environment in 1997. The colloquia were hosted in the UK House of Lords. This paper summarises the debates of those colloquia, and discusses some of the ethical and cultural issues that arise.

In the work here presented, we apply textual and sequential methods to assess the outcomes of an unconstrained multiparty dialogue. In the context of chat transcripts from a collaborative learning scenario, we demonstrate that while low-level textual features can indeed predict student success, models derived from sequential discourse act labels are also predictive, both on their own and as a s...
