Conversations provide an intuitive and simple model for analyzing interactions among composite web services. A conversation is the global sequence of messages exchanged among the peers participating to a composite web service. Interactions in a composite web service can be analyzed by investigating the temporal properties of its conversations. Conversations can be specified in a top-down or bot...

this article aims to study an important principle in discourse analysis, which belongs to paul grice, the contemporary philosopher. he believes that in addition to giving and taking information during a conversation, people also show their cooperation with each other, and so he suggests the ‘cooperative principle’ which contains some principles of subtext. since the cooperative principle is wit...

A number of software environments have been developed as media to support collaborative knowledge building, typically featuring a Web-based threaded discussion facility. We have recently developed such a system, known as WEBGUIDE. The distinctive feature of this system is support for structuring collaboration and knowledge construction with personal, group and comparison perspectives. While pil...

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 ...

Analyzing complex online relationships is a difficult job, but new information visualization tools are enabling a wider range of users to make actionable insights from the growing volume of online data. This paper describes the challenges and methods for conducting analyses of threaded conversations such as found in enterprise message boards, email lists, and forums. After defining threaded con...

Despite the fact that there are a wide range of strategies used to foster interactions in EFL conversation classrooms, many novice teachers are not aware of them. In view of this problem, the current study aimed to identify such strategies commonly used by EFL teachers in conversation classrooms. To this end, fifty sessions of college level conversation classrooms were observed andtheir teacher...

The present research aimed at investigating the interaction of the classroom talk to have a better understanding of the teachers’ practice teaching which can pave the way for reflection on teaching. The study benefitted from conversation analytic perspective to qualitatively and interpretively examine the classroom discourse of the teacher-learner interaction. The classroom talk was analyzed th...
