BBS(Bulletin Board Systems) is one of the most common places for threaded discussion. It becomes more and more popular among web users, especially in China. Everyday a huge amount of new discussions are generated on BBS. It is too difficult to find hot topics. To solve this issue, we propose a novel approach to detect hot topics on BBS for any period of time. Our solution consists of three step...

Gordon Pask’s conversation theory stands as a major contribution to cybernetics, education and epistemology. Ranulph Glanville was Pask’s student. He made himself familiar with conversation theory and promoted it in his lecture and writings throughout his career. In doing so, he made significant contributions. I summarise some of these here. To set the scene, I briefly outline some of the main ...

This paper discusses issues, possibilities and existing approaches for fitting an exception handling mechanism (EHM) in CSP-based process-oriented software architectures. After giving a survey on properties desired for a concurrent EHM, specific problems and a few principal ideas for including exception handling facilities in CSP-designs are discussed. As one of the CSP-based frameworks for con...

An experimental study of asynchronously communicating dyads tested the claim that conceptual representations could more effectively support collaborative knowledge construction in online learning than threaded discussions. Results showed that users of conceptual representations created more hypotheses earlier in the experimental sessions and elaborated on hypotheses more than users of threaded ...

Gordon Pask developed not only a Conversation Theory, but also a (less well-known) Interaction of Actors Theory, partly in response to demands during the time he worked in Amsterdam. The paper aims to clarify how this Theory intended to minimise the effcts of use on scientific results, while maximimising the help such results to improve on actions. This would facilitate empirical study of what ...

Spoken dialog systems have been widely used, such as the voice applications or agents in smart phone or smart car environments. However, speech systems are built using the developers’ understanding of the application domain and of potential users in the field, driven by observations collected by sampling the population at a given time. Therefore, the deployed models may not perfectly fit the re...
