Exploring Semantic Description and Matching Technologies for Enhancing the Automatic Composition of
In the implementation of e-learning frameworks, a problem still unsolved is how to use and integrate low-level learning services to compose more complex high-level services or tools that make sense to both tutors and learners. In that sense semantic description of Grid learning Services appears like a powerful tool to be used for discovering and matching learning services depending of a set of parameters inside the learning framework. These parameters must represent significant functional charac

An Experimental Study on Peer Selection in a P2P Network over PlanetLab
Peer selection is an important aspect in many P2P applications requiring efficient assignment and execution of jobs to peer nodes and search and file transfer, among others. Due to increasing interest of using P2P systems for distributed computing, peer selection is taking relevance and several models have been proposed in the P2P literature. Yet, there are very few experimental studies for peer selection in P2P networks deployed in real large scale networks. In this work we present an experimen

A Grid-Based Approach for Processing Group Activity Log Files
The information collected regarding group activity in a collaborative learning environment requires classifying, structuring and processing. The aim is to process this information in order to extract, reveal and provide students and tutors with valuable knowledge, awareness and feedback in order to successfully perform the collaborative learning activity. However, the large amount of information generated during online group activity may be timeconsuming to process and, hence, can hinder the rea

A Grid-aware Implementation for Providing Effective Feedback to On-line Learning Groups
Constantly providing feedback to on-line learning teams is a challenging yet one of the latest and most attractive issues to influence learning experience in a positive manner. The possibility to enhance learning group’s participation by means of providing appropriate feedback is rapidly gaining popularity due to its great impact on group performance and outcomes. Indeed, by storing parameters of interaction such as participation behaviour and giving constant feedback of these parameters to the

Semantic Description of Grid Based Learning Services
Grid technology has emerged as a powerful tool to increase the capabilities of e-learning frameworks. Learning services are fundamental components representing functionalities that can be easily reused without knowing the details of how services have been implemented. On the one hand, a problem that still remains unsolved is how to use and integrate low-level learning services to compose more complex high-level services or tools that make sense to both tutors and learners.

Efficient Embedding of Information and Knowledge into CSCL Applications
This study aims to explore two crucial aspects of collaborative work and learning: the importance of enabling CSCL applications, on the one hand, to capture and structure the information generated by group activity and, on the other hand, to extract the relevant knowledge in order to provide learners and tutors with efficient awareness and support as regards collaboration. To this end, we first identify and define the main types of information generated in online group activity and then propose

Improvement of JXTA protocols for supporting reliable distributed applications in P2P systems
In any distributed application, the communication between the distributed processes/nodes of the distributed systems is essential for both reliability and efficiency matters. In this work we address this issue for distributed applications based on JXTA protocols. After a careful examination of the current version of JXTA protocols, we observed the need for improving the original JXTA protocols, such as pipe services, to ensure reliable communication between peer nodes and the discovery and prese

A Service-oriented Platform for the Enhancement and Effectiveness of the Collaborative Learning Proc
Modern on-line collaborative learning environments are to enable and scale the involvement of an increasing large number of single/group participants who can geographically be widely distributed, and who need to transparently share a huge variety of both software and hardware distributed learning resources. As a result, collaborative learning applications are to overcome important non-functional requirements arisen in distributed environments, such as scalability, flexibility, availability, inte

Contextualizing Discussions in Distance Learning Systems
In distance learning systems, communication tools are rarely integrated into learning activities, which does not encourage their use. The main goal of our work is to mitigate this lack of integration. Our aim is to bring the discussion activities closer to the learning activities, i.e. to situations to which the discussions must ideally relate to in order to promote learning between students. Thus, we suggest two models of forum which are contextual and based on a structuring of discussions resp

KMsim: A Meta-Modelling Approach and Environment for Creating Process-Oriented Knowledge Management
This paper presents a new approach to modelling process-oriented knowledge management (KM) and describes a simulation environment (called KMSIM) that embodies the approach. Since the beginning of modelling researchers have been looking for better and novel ways to model systems and to use appropriate software to create simulations. The application of the approach and KMSIM make it possible to create realistic business models (BMs) and simulate the consequences of KM interventions and events. The

Database technology has significant economic impact and the demand for database design can not be covered by the existent educated experts. Furthermore the database management systems available at schools could be used for the design and implementation of high quality learning activities. Databases are general purpose modeling environments that enable problem solving using conceptual frameworks closer to the s

Collaboration Activity Function: An interaction analysis’ tool for Computer Supported Collaborative
During the last years, an increased interest has been observed on tools analyzing collaborative interactions that could be useful for researchers, teachers, or even students. The paper presents such a tool, based on the formally defined collaborative activity function (CAF). The empirical evaluation of CAF is also presented. The evaluation is focused on teachers using CAF during and after sessions of synchronous collaborative problem solving among students.

Shared conceptualisations in weblogs
In this paper we investigate how conceptualisations can be identified in weblogs using language technology (automated text analysis). We focus on getting a handle on both the concepts bloggers use and the way they think these concepts are related. The analysis of these conceptualisations can then be applied to a single weblog, resulting in a visualisation of potential conceptualisations the blogger wants to share with the outside world. Another type of analysis is to determine the overlap, or sh

Scripting argumentation in technology enhanced learning: a proposed system architecture
Argumentative knowledge construction is an important component of critical thinking. Learners who collaboratively argue about a subject can potentially develop domain knowledge and have the opportunity to use evidence critically in order to make sense of the subject under consideration. Moreover learners have to take into account claims and evidence of each other during argumentation and in this way they develop mental models for argument construction and sequence. However, research indicates th

E-learning environments in medical education: how pervasive computing can influence the educational
As pervasive computing is integrated incrementally with all facets of everyday life, it is reasonable to expect that its further proliferation may influence educational activities as well. Several such arguments have been thoroughly discussed in literature and several projects have been developed. However, little work has been done to investigate how pervasive computing can influence the medical educational process using e-learning platforms, and the prerequisites for such endeavours.
