Grids are increasingly being used in applications, one of which is e-learning. As most of business and academic institutions (universities) and training centres around the world have adopted this technology in order to create, deliver and manage their learning materials through the Web, the subject has become the focus of investigate. Still, collaboration between these institutions and centres is limited. Existing technologies such as grid, Web services and agents are promising better results. In this article the authors support building our architecture Regionally Distributed Architecture for Dynamic e-Learning Environment (RDADeLE) by combining those technologies via Java Agent DEvelopment Framework (JADE). By describing these agents in details, they prove that agents can be implemented to work well to extend the autonomy and interoperability for learning objects as data grid.

With the increasingly huge amount of data located in various databases and the need for users to access them, distributed information retrieval (DIR) has been at the core of the preoccupations of a number of researchers. Indeed, numerous DIR systems and architectures have been proposed including the broker-based architecture. Moreover, providing DIR with more flexibility and adaptability has led researchers thinking to build DIR with software agents. Thus, this research proposes a design and an implementation of a novel system based on the broker-based architecture and the peer-to-peer (P2P) network called broker-based P2P network. The proposed architecture is implemented with a multi-agent system (MAS) where the main agent playing the role of the broker, receives query from a peer agent and forwards them to other peer agents each with their index and resources. Upon completing retrieval process at each peer agent, results are directly sent to the peer agent that initiated the query without using the broker agent. Java Agent DEvelopment framework (JADE) is used to implement the agents and, for experiments, TERRIER (TERabyte RetRIEveR) is extended and used as the search engine to retrieve the Text Retrieval Conference (TREC) collections dataset notably TREC-6. The peer agent that originated the query progressively collects results coming from other peer agents, normalises and merges them and then proceeds with re-ranking. For normalisation, MinMax and Sum that are unsupervised normalisation methods are used.

Stock Market plays a vital role in the economy of every nation. Having a transparent market may boost the confidence of not only stock brokers but also that of investors. One of the major problems that make investors to shy away from the market is lack of transparency. Another Problem which affect the market regulators is the lack of a system that enable them to check for compliance easily. In this work, an agent based distributed framework is presented. The idea behind the proposed system is that having one system that will serve all the market stake holders will guaranty strict compliance to the market rules, easier to manage and difficult manipulate by the market operators. The implementation of the proposed system followed Multi-Agent Software Engineering (MaSE) Methodology. The evaluation of the system show that, the distributed system developed using Java Agent Development Framework (JADE) is capable of addressing problems of reliability, compliance and transparency.

Educational Contents

The main aim of the AHKME e-learning platform is to provide a system with adaptive and knowledge management abilities for students and teachers. This system is based on the IMS specifications representing information through metadata, granting semantics to all contents in the platform, giving them meaning. In this platform, metadata is used to satisfy requirements like reusability, interoperability and multipurpose. The system provides authoring tools to define learning methods with adaptive characteristics, and tools to create courses allowing users with different roles, promoting several types of collaborative and group learning. It is also endowed with tools to retrieve, import and evaluate learning objects based on metadata, where students can use quality educational contents fitting their characteristics, and teachers have the possibility of using quality educational contents to structure their courses. The learning objects management and evaluation play an important role in order to get the best results in the teaching/learning process.

Load-Balancing is an important problem in distributed heterogeneous systems. In this paper, an Agent-based load-balancing model is developed for implementation in a grid environment. Load balancing is realized via migration of worker agents from overloaded resources to underloaded ones. The proposed model purposes to take benefit of the multi-agent system characteristics to create an autonomous system. The Agent-based load balancing model is implemented using JADE (Java Agent Development Framework) and Alea 2 as a grid simulator. The use of MAS is discussed, concerning the solutions adopted for gathering information policy, location policy, selection policy, worker agents migration, and load balancing.

This work describes Techland, an OpenSim-based VW developed and owned by the author for educational purposes for middle school students. Techland is a group of islands focused on math, and science, where explore various approaches to VW, in different and mutually not exclusive learning sets and degrees of immersion. The main objectives are to simplify abstract concepts by using scripted 3D learning objects and to engage students offering a way to go beyond the classroom as the only learning environment. So Techland can be considered a giant 3D book. Activities range from viewing the contents of the world on an IWB, as a support for the teacher's lesson, to logging on the student's avatars into the world for exploration, producing machinima videos and collaborating together. Most islands are public access and reachable from other similar virtual worlds by the HG system, so other schools could take advantage from its contents or they could share projects. Techland has got the proper requirements to will become a meeting place between students and teachers who want to find new approaches to scientific matters.

Collaborative Learning Environment

The increasing advances of new Internet technologies in all application domains have changed life styles and interactions. E-learning and collaborative learning environment systems are originated through such changes and aim at providing facilities for people in different times and geographical locations to cooperate, collaborate, learn and work together by using various educational services. One of the most important requirements of learners in online and virtual environments is the ability to ask questions and receive appropriate answers. The nature of such environments and the lack of physical existence of teachers make such issues critical and challenging problems. This paper presents a multi-agent system for building a question-answering system in learning management systems and collaborative learning environments. In the proposed system, after validating the content of questions, all available resources including course materials, frequently asked questions and responses from other learners will be gathered and finally using a recommender system, the most appropriate answer(s) with respect to several criteria such as learner’s knowledge, research background, history of previous questions, and the candidate answers relevant to the question will be suggested. A simplified version of the system has been implemented and integrated to a well known open source collaborative learning environment system in order to simulate and evaluate the applicability and appropriateness of the proposed system. The result shows that the proposed question-answering system may be used efficiently and expanded to accommodate further advanced capabilities.

This chapter discusses the cultural paradigm of ‘innovative artefacts’ in the workplace. This cultural paradigm is one of two proposed paradigms that shape socio-culturally insensitive, technological artefactual approaches to workplace e-learning research and study. Subsequently, this paradigm also socially reshapes workplace e-leaning historicity for workplace adult education and training, resulting in socio-cultural impacts on the workforce. Technological innovation and business process change dominate workplace transformations. At the same time, any discussion on the socio-cultural impacts of workplace e-learning must also take into account that workplace e-learning is arguably both a technological innovation and as well as a business administration process, all of which affect adult learning in the workplace. Critical theory problematizes these relations between technology and technological progress as well as workplace e-learning. The ‘presumption of neutrality’ is highlighted as it influences the shaping of workplace e-learning and its dubious, shifting, and reversible impacts on the workforce. A focused discourse analysis of the connotations and assumptions that have further shaped e-learning for the workplace over the past decade illustrate workplace e-learning’s changing emphases over the years, from administrational to associational to artefactual, today. The technological artefacts of workplace elearning now deserve closer scrutiny. The similarities and differences between ‘online learning and simulations’, ‘learning objects’, and ‘learning management systems’ are highlighted as each of these technological artefacts, more often than not, is taken as equivalent to and a substitute for learning. The ‘presumption of neutrality’ now also comes to fruition in the ‘infallibility paradox’ for workplace e-learning. For workplace e-learning, adherence to the belief in the infallibility of innovative artefacts leads to two workplace e-learning scenarios: (a) instrumental instruction (see Chapter 7); and, (b) rational training (see Chapter 8).
