| |  | Nilsson, Mikael | SemanticWeb Meta-data for e-Learning - Some Architectural Guidelines read moreAbstract: Meta-data is the fundamental building block of the Semantic Web. However,
the meta-data concept is too loosely defined to provide architectural
guidelines for its use. This paper analyzes important uses of meta-data in
the e-learning domain, from a pedagogical and philosophical point of view,
and abstracts from them a set of fundamental architectural requirements for
Semantic Web meta-data. It also describes some flexible generic techniques
for working with meta-data, following these requirements. Finally, the paper
describes a Semantic Web-based e-learning architecture based in these
requirements and techniques currently under development at the Knowledge
Management Research Group at CID (Centre for user oriented IT Design)
at KTH, the Royal Institute of Technology in Stockholm. This architecture
builds on Edutella, a peer-to-peer meta-data exchange network, and a technique
called conceptual modeling using the Conzilla concept browser, a new
kind of knowledge management tool for conceptual navigation and exploration.  This article is not yet tagged | 2002 |
| | | Naeve, Ambjrn | E-Learning in the Semantic Age read moreAbstract: Today educational technologies are reaching a state that allows interoperability and
reuse of learning resources. The underlying techniques rely heavily on the standards
movement for metadata representation. On top of this, monolithic reference
platforms are being developed with the aim to ease application development.
However, we do not think this approach is flexible enough to embrace future
learning techniques. In contrast, we suggest a learning framework where services can
be developed and exchanged between as well as within systems. A fundamental part
of this framework is the semantic layer, which builds on the structure of the Semantic
Web. Hence we do not regard metadata as something 'objective' that you have to
download from some central server. On the contrary, metadata should be allowed to
consist of subjective views of resources that are distributed and shared in contexts
that can evolve dynamically. In support of such requirements, our learning
framework consists of a combination of semantic web techniques and peer-to-peer
services for search, retrieval, publication, replication and mapping of metadata. This article is not yet tagged | |
