Finding your way into an open online learning community

Making educational materials freely available on the web is not only a noble enterprise, but also fits the call of helping people to become lifelong learners; a call which gets louder and louder every day. The world is rapidly changing, requiring us to continuously update our knowledge and skills. A problem with this approach to lifelong learning is that the materials that are made available are often both incomplete and unsuitable for independent learning in an online setting. The OpenER (Open Educational Resources) project at the Open Universiteit Nederland makes more than 20 short courses, originally developed for independent-study, freely available from the website www.opener.ou.nl. For our research we start from an envisioned online learning environment now under development. We use backcasting to select research topics that form steps from the current to the ultimate situation. The two experiments we report on here are an extension to standard forum software and the use of student notes to annotate learning materials: two small steps towards our ultimate open learning environment

Reducing the "Information Gap" Between Synchronous and Asynchronous Co-operative Design Phases

This paper aims to describe a particular role of annotations as co-operative artefacts in engineering design. In co-operative processes, where achieving a shared understanding between the participants from different domains is crucial, sharing the decisions and argumentations which lead to a solution is as important as sharing the solution itself. In our case study, we describe what we call an "information gap" between the asynchronous phase, when individual decisions are made, and the design review, when the solution is evaluated, and collective thinking influences the decisions. Then, within a conceptual design scenario, we show how semantic annotations can create a shared environment to help to reduce this gap, where all actors are able to elicit domain-specific constraints and engage discussions on design solution during the asynchronous phase.semantic annotation; engineering design; design communication; collaborative tool

Our extended senses, tools, technologies, through the ages, have been closed systems incapable of interplay or collective awareness. Now, in the electric age, the very instantaneous nature of co-existence among our technological instruments has created a crisis quite new in human history. Our extended faculties and senses now constitute a single field of experience which demands that they become collectively conscious. Our technologies, like our private senses, now demand an interplay and ratio that makes rational co-existence possible. As long as our technologies were as slow as the wheel or the alphabet or money, the fact that they were separate, closed systems was socially and psychically supportable. This is not true now when sight and sound and movement are simultaneous and global in extent. (McLuhan 1962, p.5, emphasis in original)Over forty years later, the seamless interplay that McLuhan demanded between our technologies is still barely visible. McLuhan’s predictions of the spread, and increased importance, of electronic media have of course been borne out, and the worlds of business, science and knowledge storage and transfer have been revolutionised. Yet the integration of electronic systems as open systems remains in its infancy.Advanced Knowledge Technologies (AKT) aims to address this problem, to create a view of knowledge and its management across its lifecycle, to research and create the services and technologies that such unification will require. Half way through its sixyear span, the results are beginning to come through, and this paper will explore some of the services, technologies and methodologies that have been developed. We hope to give a sense in this paper of the potential for the next three years, to discuss the insights and lessons learnt in the first phase of the project, to articulate the challenges and issues that remain.The WWW provided the original context that made the AKT approach to knowledge management (KM) possible. AKT was initially proposed in 1999, it brought together an interdisciplinary consortium with the technological breadth and complementarity to create the conditions for a unified approach to knowledge across its lifecycle. The combination of this expertise, and the time and space afforded the consortium by the IRC structure, suggested the opportunity for a concerted effort to develop an approach to advanced knowledge technologies, based on the WWW as a basic infrastructure.The technological context of AKT altered for the better in the short period between the development of the proposal and the beginning of the project itself with the development of the semantic web (SW), which foresaw much more intelligent manipulation and querying of knowledge. The opportunities that the SW provided for e.g., more intelligent retrieval, put AKT in the centre of information technology innovation and knowledge management services; the AKT skill set would clearly be central for the exploitation of those opportunities.The SW, as an extension of the WWW, provides an interesting set of constraints to the knowledge management services AKT tries to provide. As a medium for the semantically-informed coordination of information, it has suggested a number of ways in which the objectives of AKT can be achieved, most obviously through the provision of knowledge management services delivered over the web as opposed to the creation and provision of technologies to manage knowledge.AKT is working on the assumption that many web services will be developed and provided for users. The KM problem in the near future will be one of deciding which services are needed and of coordinating them. Many of these services will be largely or entirely legacies of the WWW, and so the capabilities of the services will vary. As well as providing useful KM services in their own right, AKT will be aiming to exploit this opportunity, by reasoning over services, brokering between them, and providing essential meta-services for SW knowledge service management.Ontologies will be a crucial tool for the SW. The AKT consortium brings a lot of expertise on ontologies together, and ontologies were always going to be a key part of the strategy. All kinds of knowledge sharing and transfer activities will be mediated by ontologies, and ontology management will be an important enabling task. Different applications will need to cope with inconsistent ontologies, or with the problems that will follow the automatic creation of ontologies (e.g. merging of pre-existing ontologies to create a third). Ontology mapping, and the elimination of conflicts of reference, will be important tasks. All of these issues are discussed along with our proposed technologies.Similarly, specifications of tasks will be used for the deployment of knowledge services over the SW, but in general it cannot be expected that in the medium term there will be standards for task (or service) specifications. The brokering metaservices that are envisaged will have to deal with this heterogeneity.The emerging picture of the SW is one of great opportunity but it will not be a wellordered, certain or consistent environment. It will comprise many repositories of legacy data, outdated and inconsistent stores, and requirements for common understandings across divergent formalisms. There is clearly a role for standards to play to bring much of this context together; AKT is playing a significant role in these efforts. But standards take time to emerge, they take political power to enforce, and they have been known to stifle innovation (in the short term). AKT is keen to understand the balance between principled inference and statistical processing of web content. Logical inference on the Web is tough. Complex queries using traditional AI inference methods bring most distributed computer systems to their knees. Do we set up semantically well-behaved areas of the Web? Is any part of the Web in which semantic hygiene prevails interesting enough to reason in? These and many other questions need to be addressed if we are to provide effective knowledge technologies for our content on the web

Digital document and interpretation : re-thinking "text" and scholarship in electronic settings

The contribution starts from outlining the evolution of the scholarly production flow from the print based paradigm to the digital age and in this context it explores the opposition of digital versus analog representation modes. It then develops on the triple paradigm shift caused by genuine digital publishing and its specific consequences for the social sciences and humanities (SSH) which in turn results in re-constituting basic scholarly notions such as 'text' and 'document'. The paper concludes with discussing the specific value that could be added in systematically using digital text resources as a basis for scholarly work and also states some of the necessary conditions for such a 'digital turn' to be successful in the SSH.Der Beitrag beginnt mit einem Überblick zur Evolution des wissenschaftlichen Informationskontinuums auf dem Weg vom druckbasierten Paradigma in das digitale Zeitalter und geht in diesem Zusammenhang näher auf die Unterscheidung 'digitaler' und 'analoger' Repräsentationsmodi ein. Anschließend behandeln wir den als Folge des Übergangs zu genuin digitalen Publikationsformen erwartbaren dreifachen Paradigmenwechsel und dessen spezifische Konsequenzen für die Geistes- und Sozialwissenschaften sowie als deren Folge wiederum die Re-Konstitution elementarer Kernbegriffe geisteswissenschaftlichen Arbeitens wie 'Text' und 'Dokument'. Der Beitrag schließt mit einer Betrachtung des spezifischen Mehrwerts, der sich aus dem systematischen Rekurs auf digitale Textressourcen in den Geisteswissenschaften ergeben könnte und geht dabei auch auf die erforderlichen Vorbedingungen eines solcherart erfolgreichen 'digital turn' in den Geistes- und Sozialwissenschaften ein

Collaborative yet independent: Information practices in the physical sciences

In many ways, the physical sciences are at the forefront of using digital tools and methods to work with information and data. However, the fields and disciplines that make up the physical sciences are by no means uniform, and physical scientists find, use, and disseminate information in a variety of ways. This report examines information practices in the physical sciences across seven cases, and demonstrates the richly varied ways in which physical scientists work, collaborate, and share information and data. This report details seven case studies in the physical sciences. For each case, qualitative interviews and focus groups were used to understand the domain. Quantitative data gathered from a survey of participants highlights different information strategies employed across the cases, and identifies important software used for research. Finally, conclusions from across the cases are drawn, and recommendations are made. This report is the third in a series commissioned by the Research Information Network (RIN), each looking at information practices in a specific domain (life sciences, humanities, and physical sciences). The aim is to understand how researchers within a range of disciplines find and use information, and in particular how that has changed with the introduction of new technologies
