In this paper we propose a framework for modeling, representing populating and enriching information from online collaborative sessions within Web forums. The main piece of the framework is an ontology called Collaborative Session Conceptual Schema (CS) that allows for specifying collaborative sessions. The paper describes the information this ontology needs to know, the alignment of the ontolo...

In this chapter we describe ongoing work towards enabling dynamic support for collaborative learning in the Virtual Math Teams (VMT) environment using state-of-the-art language technologies such as text classification and dialogue agents. The key research goal of our long-term partnership is to experimentally learn broadly applicable principles for supporting effective collaborative problem sol...

Working collaboratively holds many benefits for learners. However, varying incoming knowledge and attitudes toward collaboration present challenges and can lead to frustration for students. An important open question is how to support effective collaboration and foster equity for students with different levels of incoming preparation. In this study, we compared two collaborative instructional a...

This paper explores the regulatory philosophies underlying the debates on privacy in e-commerce in the European Union and the United States. It offers a framework to grasp these differences and suggests that, in the ultimate, e-commerce players with transatlantic ambitions may need different organizations to deal with the EU and US

In this chapter, we examine the phenomenon of compound contributions (CCs) and the implications for NLG in interactive systems. Compound contributions are contributions in dialogue which continue or complete an earlier contribution, thus resulting in a single syntactic or semantic (propositional) unit built across multiple contributions, provided by one speaker or more than one (1.1). The term ...

In this paper, we give an issue-based account of a simple kind of collaborative negotiative dialogue. We start from a previous formal account of negotiative dialogue (Sidner, 1994a) and argue for a slightly different idea of what negotiative dialogue is. We want to make a distinction between the process of accepting an utterance and its content, which applies to all utterances, and a concept of...

BACKGROUND There is a need to understand scientific evidence in light of the context within which it will be used. Deliberative dialogues are a promising strategy that can be used to meet this evidence interpretation challenge. METHODS We evaluated a deliberative dialogue held by a transnational violence prevention network. The deliberative dialogue included researchers and knowledge user par...
