Autonomous search in a social and ubiquitous Web

International audienceRecent W3C recommendations for the Web of Things (WoT) and the Social Web are turning hypermedia into a homogeneous information fabric that interconnects heterogeneous resources: devices, people, information resources,abstract concepts, etc. The integration of multi-agent systems with such hypermedia environments now provides a means to distribute autonomous behavior in worldwide pervasive systems. A central problem then is to enable autonomous agents to discover heterogeneous resources in world wide and dynamic hypermedia environments. This is a problem in particular in WoT environments that rely on open standards and evolve rapidly—thus requiring agents to adapt their behavior at runtime in pursuit of their design objectives. To this end, we developed a hypermedia search engine for the WoT that allows autonomous agents to perform approximate search queries in order to retrieve relevant resources in their environment in(weak) real time. The search engine crawls dynamic WoT environments to discover and index device metadata described with the W3C WoT Thing Description, and exposes a SPARQL endpoint that agents can use for approximate search. To demonstrate the feasibility of our approach, we implemented a prototype application for the maintenance of industrial robots in worldwide manufacturing systems. The prototype demonstrates that our semantic hypermedia search engine enhances the flexibility and agility of autonomous agents in a social and ubiquitous Web

Design approaches in technology enhanced learning

Design is a critical to the successful development of any interactive learning environment (ILE). Moreover, in technology enhanced learning (TEL), the design process requires input from many diverse areas of expertise. As such, anyone undertaking tool development is required to directly address the design challenge from multiple perspectives. We provide a motivation and rationale for design approaches for learning technologies that draws upon Simon's seminal proposition of Design Science (Simon, 1969). We then review the application of Design Experiments (Brown, 1992) and Design Patterns (Alexander et al., 1977) and argue that a patterns approach has the potential to address many of the critical challenges faced by learning technologists

Designing the interface between research, learning and teaching.

Abstract: This paper’s central argument is that teaching and research need to be reshaped so that they connect in a productive way. This will require actions at a whole range of levels, from the individual teacher to the national system and include the international communities of design scholars. To do this, we need to start at the level of the individual teacher and course team. This paper cites some examples of strategies that focus on what students do as learners and how teachers teach and design courses to enhance research-led teaching. The paper commences with an examination of the departmental context of (art and) design education. This is followed by an exploration of what is understood by research-led teaching and a further discussion of the dimensions of research-led teaching. It questions whether these dimensions are evident, and if so to what degree in design departments, programmes and courses. The discussion examines the features of research-led departments and asks if a department is not research-led in its approach to teaching, why it should consider changing strategies

Thriving in a colder and more challenging climate

Hawkridge, D., Ng, K., & Verjans, S. (Eds.) (2011). Thriving in a colder and more challenging climate. The 18th annual conference of the Association for Learning Technology (ALT-C 2011). September, 6-8, 2011, University of Leeds, England, UK. URI:http://repository.alt.ac.uk/2159Here are the proceedings of the 2011 ALT Conference ‘‘Thriving in a colder and more challenging climate’’. Proceedings papers report on a piece of research, possibly in its early stages, or they can be ‘‘thoughtpieces’’ which state a point of view or summarise an area of work, perhaps giving new insights. The conference has six themes: . Research and rigour: creating, marshalling and making effective use of evidence . Making things happen: systematic design, planning and implementation . Broad tents and strange bedfellows: collaborating, scavenging and sharing to increase value . At the sharp end: enabling organisations and their managers to solve business, pedagogic and technical challenges . Teachers of the future: understanding and influencing the future role and practices of teachers . Preparing for a thaw: looking ahead to a time beyond the disruptive discontinuities of the next few years. Interestingly, there were very few proposals for the conference as a whole against the sixth theme: and no proceedings papers. Perhaps the thaw is still perceived as being too far away to warrant any preparation yet!Association for learning technolog
