1 Introduction
Today’s popular resource sharing systems such as YouTube, Flickr, or Delicious
provide diverse types of content and do not focus on a particular domain such
as education. Petrides et al. point out that there is a need for platforms, which
allow for sharing of educational resources [1]. These platforms should permit the
storage of resources of different formats [2]. Typically, though, different Web 2.0
infrastructures focus only on particular media types, e.g. videos in YouTube,
pictures in Flickr, and bookmarks in Delicious, even if these resources belong to
one and the same learning context. In this paper, we close this gap and present
LearnWeb2.0, an elearning and competence development environment for shar-
ing educational multimedia-based resources which are spread across the Web.
2 LearnWeb2.0 – System Description
LearnWeb2.0 is fully embedded into the network of existing popular Web 2.0 sys-
tems. Therewith, we are able to seamlessly integrate LearnWeb2.0 into the users’
every day interactions with these systems [3]. Currently, LearnWeb2.0 integrates
ten different Web 2.0 services such as YouTube, SlideShare, and Bloggers and
provides various innovative features: (i) A personal learning space offering a rich
set of functions and a seamless overview of the entire set of learning resources
distributed across the various Web 2.0 repositories, (ii) sharing through stand-
ing queries, where users are notified whenever a new learning resource matches
the query, (iii) collaborative aggregation of different learning resources via an
intuitive drag-and-drop interface, (iv) integration of the user’s social networks
from different Web 2.0 services (Facebook, Delicious, Last.fm, and Flickr), and
(v) provision of a (controlled) natural language interface, which enables users to
control access to shared resources.
The LearnWeb2.0 Web platform provides a uniform interface to search for
resources that are distributed across the ten integrated Web 2.0 services. Users
can bookmark resources and collaboratively organize these bookmarks in groups
as depicted in Fig. 1.a, which shows a group of educational resources about “MS
Access”. Further, via the LearnWeb2.0 browser plug-in (Fig. 1.b) users can sim-
ply drag-and-drop images, videos, text snippets, etc. from their desktop or from
some Web site on the plug-in’s icon to upload the resource to their favorite,
appropriate Web 2.0 service and add it to LearnWeb2.0. Results of a question-
naire [3] and a user study that is currently conducted at Leibniz University
Hannover confirm the ability of LearnWeb2.0 to support learners and educators
in sharing, discovering, and managing Web 2.0 learning resources.

allows resource upload via drag-and-drop.
3 Demonstration Overview
In this demonstration we will primarily show how LearnWeb2.0 works and how a
user can employ it to efficiently develop her competences on the topic of interest.
First, we demonstrate the personal learning space which integrates all Web 2.0
resources accessible to the user and enables retrieval, sharing and management
of these resources. Next, we show how the aggregation of the user’s social net-
work can be exploited for collaborative competence development. Further, we
demonstrate how educational resources already available at user’s desktop can
be uploaded using the drag-and-drop functionality of the LearnWeb2.0 browser
plug-in. Finally, we demonstrate collaborative aggregation, annotation, rating
and commenting resources to support efficient resource finding.
