While extensive work on semantic models has been carried out, much of this work remains to be tested in real open environments. This paper describes some of the issues and challenges to be considered when combining existing semantic frameworks for effective agent communication. In particular, we describe issues related to the development of the Agentcities Network which is a large-scale open test bed for agent systems that aims to enable on-line experimentation with semantic frameworks for agent communication. The presentation is kept discursive in nature: characterizing different aspects of communication, outlining research challenges, commenting on possible strategies and describing the current status of activities in the Agentcities Network.

Distributed multi-agent systems propose new infrastructure solutions to support the interoperability of electronic services. Security is a central issue for such infrastructures and is compounded by their intrinsic openness, heterogeneity and because of the autonomous and potentially self-interested nature of the agents therein. This article reviews the work that the FIPA agent standards body has undertaken to specify security in multi-agent systems. This enables a discussion about the main issues that developers have to face at different levels (i.e., intra-platform, inter-platform and application level) when developing agent-based security solutions in various domains. 1

This paper considers the main challenges concerning security that need to be overcome for Multi Agent Systems (MAS) to succeed in business enterprises. We outline the main design issues for developing agent security. Finally, we survey some specific initiatives currently underway within the FIPA agent forum that seeks to address MAS security and then we draw conclusions. Introduction of computational devices are becoming more ubiquitous. The e-business world is being driven to create and enhance technologies to support dynamic services, automated interaction, rich information exchange and tailored solutions, to underpin such open service environments. Indeed such environments ar...

Despite these successes, the vision of agents as intelligent, autonomous entities seamlessly interacting with one another in open heterogeneous environments [Hewitt90] has yet to be realised. As Nwana and Ndumu [Nwana98] point out "the devil in realising the promises of agent technology is in the details." These details include the challenging coordination, communication, discovery, trust, security and ontology issues that are found in truly open environments where agents that are owned by many different individuals and organisations can interact and interoperate.

We describe the opportunities that this approach opens up regarding interoperability and configurability of learning analytics and intelligent support. The framework is generic and can be used for any type of system with similar requirements. In this paper we present a case that covers configuration of learning analytics for teachers and intelligent support for students in constructionist mathematical e-books.

This research reports on working with a large number of schools, researchers and academics both formally and informally and across a wide age range and ability. The findings from a number of studies reflects important pedagogical theory, design and practice of teaching and learning about the computer science and engineering through tangible learning context. These findings and observations are examined in the light of these teaching and learning experiences and especially the observation of development of resilience in students learning and engagement in challenging areas of study.

In this paper we review part of the approach taken by aceMedia to create semantic metadata (ontologies) and use of this to enable more appropriate search and matching and managing of content. However, there is further benefit the end user can gain from this semantic metadata and this is from adding intelligence in the software. The benefits and how intelligence can be added is described with a particular focus on assisting the user in the creation of privacy preference rules when sharing content: the creation of self-governing inferencing.

In the project we use the concept of the curiosity cabinet as our core 'learning enabling' metaphor. To enable the creation of learning experiences we are combining the curiosity cabinet metaphor with a set of artefacts (real of virtual objects) so that educators can set the stage for the learning experience. Moreover, we also facilitate learners to design and create their learning spaces by accessing the artefacts collection and selecting items they find appropriate to include in their spaces attaching additional information related to the respective learning experience. Therefore, learning spaces created during a learning experience support both highly individualized curiosity cabinets as well a shared space to co-design, co-create and share the learning artefacts. This supports both the personalized learning spaces for the individual learning to develop agency of learning, as well as collaborative group learning spaces. These personalized and collaborative learning spaces evolve over time to reflect changes in the learning and development and, habits and needs of each particular learner or group of learners.

We review a set of multi-agent architectures starting from the communication and co-ordination requirements of such systems. The aim is to illustrate the common components in current designs and implementations of MAS which are often based on the communication nature of these systems. Further to this we show some benefits and drawbacks of these systems that are developed form this aspect. Part of the limitations of these systems is due to basing their communication semantic interpretation on the belief desire and intention model (BDI) which is a mental agency. The mental agency is used for the internal reasoning part of the agent and places implicit assumptions on the communication behaviour. We examine this limitation and report on how two MASs overcome some of the constraints. In light of these practical solution...

A community of interest consists of several stakeholders from various ‘Communities of Practice’ (Wenger, 1998). In this paper we outline the creation of an English CoI describing the development of a cBook on numbers and equivalence. We use a design-based research methodology approach for teachers, designers, researchers, teacher-educators jointly working on cBooks as ‘boundary objects’ (Akkerman & Bakker, 2011) to facilitate thinking about creative mathematical thinking and social creativity. We illustrate our design-based approach through the example artefacts created during the different stages of development of the cBooks. The details of our approach provide a blueprint for the formation of CoI’s by working on digital, interactive, creative, mathematics textbooks.

It enables teachers to: build on the work of others, adopt and adapt learning designs, analyse and test their designs, and then share their own teaching ideas and experience using the tool. The Learning Designer is one of the outputs of a three-year research project*, which investigated how to support teachers developing their design skills and knowledge in order to profit from the creative possibilities opened up by digital technologies. Evaluations from teachers using the learning design tool demonstrated that it helps teachers in all sectors of education. The Learning Designer tool is used across the world in the exchange of knowledge when delivering formal and informal “teaching.” It is underpinned by a theoretically-informed model of learning and by empirical work with teaching practitioners, and uses Semantic Web technologies for developing this knowle...

The cBooks are authored in a Digital Mathematics Environment in which participants can construct books with various interactive ‘widgets’. This paper provides an outline of the MC-squared project illustrating an interactive storyboard of the Digital Mathematics Environment architecture. This includes examples of how authoring by cBook designers of interactive ‘widgets’ is possible. The workshop that relates to this paper is augmented, of course, by suitable ‘hands-on’ materials aimed at two possible cBooks: one focusing on aspects of geometric and spatial thinking using building blocks, the other on aspects of number and fractions.

The apphcation required adaptive planning in a reactive and generative environment. To model the application, it was necessary for multiple agents to be developed which added the usual communication [15, 19] issues. The planning environment needed to deal with both reactive and generative problems. To provide a unified and adaptative environment we used reflection [20, 13, 4, 18]. Lilies provides a framework which develops and extends the taxonomy of actions [16] and the interleaving [1] for planning environments. To deal with the planning in a reactive and generative environment, and having only partial information required a system which could evaluate, interleave and adapt on both single and multiple agent(s) model. this paper we explain why and how we developed Lilies, a system which provides agents with a means of inspection and introspection [4].
