The core idea of a Concept Browser is to visualize structured information in the form of context-maps. When storing context-maps the language for the Semantic Web, RDF (Resource Description Framework), is utilized. For a thin client Concept Browser to be able to painlessly display a context-map, it is crucial to minimize the strain of loading and processing it. Hence, it is necessary to avoid the verbose RDF expression in XML as well as minimizing the information that is sent. The server side solution introduced in this thesis solves this by filtering out the information that is strictly necessary for a given context-map and then sends this information to the client over a specially designed protocol.

Based on those observations an approach for supporting learning in knowledge work is proposed considering requirements from e-learning as well as from knowledge management. In addition to traditional e-learning, on-demand e-learning takes the current situation of the knowledge worker into consideration to ensure learning support of knowledge work is proposed. For using a broad variety of resources in on demand e-learning a single metadata schema for describing seems not sufficient for every organisation. Therefore, application profiles appear adequate for describing resources used in the proposed approach for arranging knowledge elements. Identifying the knowledge workers current situation a learning need should be derived and to use it afterwards for selecting and delivering knowledge elements.

This paper describes a proposed formalization of the notion of Applica-tions Profiles as used in the Dublin Core community. The formalization, called Description Set Profiles, defines syntactical constraints on metadata records con-forming to the DCMI Abstract Model using an XML syntax. The mapping of this formalism to syntax-specific constraint languages such as XML Schema is dis-cussed.

More specifically, it presents how an application profile of the IEEE LOM standard has been developed for the description of learning objects on organic agriculture and agroecology. Then, it describes the design and prototype development of the Organic.Edunet repository tool: a Web-based for annotating learning objects on organic agriculture and agroecology, organizing them in using a portfolio-like user interface in a learning repository, and then federating this repository with a network of agricultural learning repositories.

The use of RDF on the web is increasing, unfortunately the amount of editing tools suitable for end users without knowledge of technicalities of the language are not so common. We believe that a vital ingredient for the editing tools to flourish is a working remote modification protocol. This will allow editing tools to be developed separately from triplestores and make them more flexible and reusable. Several initiatives for remote modification exists already but have not gained wide spread adoption. In this paper we will show that most of them fall short when it comes to edit arbitrary RDF construct, especially in combination with typical requirements of editing tools. We will first list these requirements, then propose a solution and finally outline an implementation. With this implementation we will also see how annotation profiles, a configuration mechanism for RDF metadata editors, has the additional feature of making modi...

This was distributed as a printed booklet and the intention was that junior hematologist could use it for personal competence development. In the EU-funded project H-net this Curriculum has been adapted into the a web environment by using RDF and placed inside a web portfolio system. How this is done is further described in this article. Furthermore, the possibilities of reusing the curriculum in ways that was not initially intended is described, such as describing Learning Resources inside the web-portfolio system with how they relate to different parts of the curriculum. That way a search for learning resources inside the portfolio by using the curriculum is enabled. And, since the medical field of hematology is closely related to other medical fields the design of the web-version of the curriculum was done in a way that builds for possible combination with any other

People with no or little knowledge about RDF are therefore forced to use simplified and often domain-specific tools that work with fixed sets of metadata elements. This paper introduces the Annotation Profile Model as a configuration mechanism from which annotation tools can be automatically generated. The intention is to encourage metadata- or domain experts to define annotation profiles according to metadata vocabularies. This will allow end-users or administrators to select appropriate annotation profiles for the task at hand, and then an editor will be provided by the underlying system. This paper discusses the design of the Annotation Profile Model, which consists of a data-capturing part (the Graph Pattern Model) and a presentation part (the Form Template model). An implementation that can generate both web-based and standalone editors is also introduced.

The aim of this study was to explore how and to what extent students supported their own and other students' processes of inquiry during online tutoring. More specifically, question and answer sessions (Q&As) were studied, and online tutoring transcripts were analyzed using the Relationship of Inquiry coding scheme adapted from the Community of Inquiry framework. The students interacted voluntarily with each other and with the teachers. The results show that the students supported both their own process of inquiry as well as other students' process of inquiry. Furthermore, the results indicate that students acquired metacognitive development through self- and co-regulation when they expressed teaching presence. Overall, we conclude that Q&As have the potential to support student learning when working on assignments in STEM education.

This qualitative study investigates the interactions between learners, as well as between learners and teachers in MOOCs. Community of Inquiry was used as an analytical framework to unveil how the discussions made in the online environment may connect to the course participants’ learning processes. Preliminary findings indicate that the interactions taking place in the discussion forums primarily concerns issues regarding course structure. Very few posts concern challenging reasoning or, conversations that may support learners to deepen their understanding of the subject matter at hand.
