We provide a logical investigation of a simple case of communication in a network of agents called the gossip problem. Its classical version is: given n agents each of which has a secret – a fact not known to anybody else –, how many calls does it take to ...

Fundamental problem in human-robot teams is to find a set of heterogeneous robots that have to cooperate to execute a complex mission. This paper describes the Shared Knowledge Interaction Modelling (SKIM) framework for task allocation and how it is ...

The aim of this paper is to present a sliding autonomy approach for Unmanned Aerial Vehicles (UAVs) in the context of the project Fly4SmartCity. The project consists in the implementation of a cloud robotics service in which small UAVs are employed for ...

In this paper we are exploring how a process of collaborative learning evolves in an academic wiki space. In order to trace the potential of such a technological environment, we assume a comparative perspective by analyzing its specific structural ...

Decentralized, message-based communication networks commonly require mechanisms for message confidentiality and integrity. While these needs are traditionally provided through methods of channel encryption and signing, such mechanisms are often ...

Issue tracking systems help organizations manage issue reporting, assignment, tracking, resolution, and archiving. Traditionally, it is the Software Engineering community that researches issue tracking systems, where software defects are reported and ...

This paper is the result of the clashing but fruitful collaboration of experts of two different cultures - Computer Science and Archaeology _ and reports on the design and development of the T.Arc.H.N.A System, a new system of accessibility towards ...

Delivering quality customer service has emerged as a strategic imperative, one that is increasingly tied to a firm's information technology resources and capabilities. This paper presents an empirical study that examines the extent to which IT impacts ...

CSCL faces the challenge of not only designing educational technologies and interventions, but of inventing analytic methodologies and theoretical frameworks appropriate to the unique character of collaborative learning as an interactional group ...

The study analyzed how two types of graphical representation tools influence the way in which dyads use shared and unshared knowledge resources in different collaboration scenarios, and how learners represent and transfer shared knowledge under these ...

Representations and changes between them play a major role in cognitive development (e.g., Vosniadou, & Brewer, 1992) and education (e.g., Hewson, Beeth, & Thorley, 1998). By definition, change of representations is also indispensable for collaborative ...

The study investigates collaborative learning of small groups via text-based computer-mediated communication. We analyzed how two approaches to pre-structure communication influence participation, individual knowledge transfer, the convergence of ...

In this paper we explore issues to do with intersubjectivity and shared knowledge in human activity. We discuss these issues by contrasting two different views of language and communication, one being a model developed by Clark and Brennan, the other ...

Designs for CSCL applications usually presume a desktop/laptop computer. Yet future classrooms are likely to be organized around Wireless Internet Learning Devices (WILD) that resemble graphing calculators or Palm handhelds, connected by short-range ...

We can interpret meaning of the communications between users if we have large ontology on the discourses. We can link these static ontologies with multi-agents systems, and expresses the changes of the multi-agent organizations in a geometrical and ...

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 ...

This paper presents results of a study of middle school teachers using a prototype Macintosh version of CSILE to help create a knowledge-building community. The study, involving middle schools in two school districts in the Southwest United States, ...

A goal of cooperative learning is the construction of shared knowledge. Shared knowledge represents the common understanding of a group of individuals with respect to the content domain; the active construction of shared knowledge enhances acquisition ...

Computer supported collaborative learning (CSCL) offers promising innovations and tools for restructuring teaching-learning processes to prepare students for the emerging knowledge society. However, sufficient and reliable data have not been available ...

Some student difficulties in learning science can be understood by considering the background knowledge that people necessarily assume in conversations. In learning science, students have to develop meanings and understandings that can be taken as ...
