In this paper, we recommend and promote global standards of the e-Trade process on the basis of ebXML & web services. For the ebXML Frameworkbased e-Trade to be facilitated, it is urgent for each country to implement and use national ebXML registry and standardize electronic documents, electronic catalog and electronic payment. In UNCEFACT, ebXML-based UN Central Registry & Repository is in the...

Entre 2003 et 2008, les neuf États membres de l’Autorité du Bassin Niger (ABN) ont développé un processus Vision Partagée visant le développement durable bassin fleuve à travers la mise en oeuvre d’actions projets intégrateurs dimension transfrontalière. Les usages multiples l’eau gestion coordonnée des barrages sont au coeur cette politique longue haleine. L’ABN a retenu scénario d’aménagement...

Many studies have been reported in the domain of speech-to-speech machine translation systems for travel conversation use. Therefore, a large number of travel domain corpora have become available in recent years. From a wider viewpoint, speech-to-speech systems are required for many purposes other than travel conversation. One of these is monologues (e.g., TV news, lectures, technical presentat...

The authors develop a framework for the design of tools to mediate collaboration intended to lead to learning. We identify two categories of media that are common in computer-supported collaborative learning and software in general: communication media and information media. These two types of media are then mapped onto two types of social activities in which learning is grounded: dialogue and ...

Spoken monologues feature greater sentence length and structural complexity than do spoken dialogues. To achieve high parsing performance for spoken monologues, it could prove effective to simplify the structure by dividing a sentence into suitable language units. This paper proposes a method for dependency parsing of Japanese monologues based on sentence segmentation. In this method, the depen...

Collaborators generally coordinate their activities through communication, during which they negotiate a shared lexicon for activity-related objects. This social-pragmatic activity both recruits and affects cognitive and social-cognitive processes ranging from selective attention to perspective taking. We ask whether negotiating reference also facilitates category learning or might private verb...

This research used vicarious-learning procedures in an attempt to increase students’ knowledge of the domain and enhance the quality of their questions in an intelligent tutoringsystem involving computer-controlled animated agents. Students who overheard a dialogue in which a virtual tutee asked a virtual tutor questions during acquisition wrote significantly more in free recall and asked signi...
