Collaborative networked learning (hereafter CNL) was first proposed by Charles Findley in his work “Collaborative networked learning: online facilitation and software support” as part of instructional learning for the future of the knowledge worker. His premise was that through electronic dialogue learners and experts could interactively communicate within a contextual framework to resolve prob...

In this paper, we argue for the need to distinguish between task and dialogue initiatives, and present a model for tracking shifts in both types of initiatives in dialogue interactions. Our model predicts the initiative holders in the next dialogue turn based on the current initiative holders and the effect that observed cues have on changing them. Our evaluation across various corpora shows th...

In our ongoing attempt to create and support workable “rules of play” for effective, goal-driven conversations in the context of collaborative modeling, we have now reached a stage in which a first operational setup for such ‘dialogue games’ has been developed and tested. In this paper we present the basic, generic structure of a game-like procedure description, based on a prototype game for co...

Teacher professional development, as a burgeoning term, has attracted a surge of interest in English language teaching. In second language (L2) professional development, the common orthodoxy has been one which considers teachers as that of knowledge consumers. It is commonly argued that top-down approaches to teachers’ professional development has done little to maximize teachers’ professionali...

Risk management aims to discuss the probabilities and consequences of risks on the goals of a software project. In such projects, there are dependence relationships between risks, although they are not treated yet by standard risk management practices. This paper is concerned with the analysis of risk dependencies, where these risks are assessed when multiple project stakeholders are involved i...

In a collaborative risk management scenario, project stakeholders often need natural forms of recording and reusing past risk management experiences so that they could better assess whether there are threats to the goals of new projects. The contribution of this paper is to propose an enhanced case-based reasoning (CBR) approach to support project participants to exploit such experiences which ...

We describe the JAST human-robot dialogue system, which supports fully symmetrical collaboration between a human and a robot on a joint construction task. We concentrate on the dialogue manager, which is based on Blaylock and Allen’s (2005) collaborative problemsolving model of dialogue and which supports joint action between the dialogue participants at both the planning and the execution leve...
