Abstract [en]

This paper presents an application that enables loose and ad-hoc task collaboration for knowledge work and explicitly integrates task metadata into the collaboration process. With the increasing availability of semantic desktop technology, knowledge workers (KWers) can organize their personal information in a formalized way, including tasks. In an organization, KWers need to collaboratively access task-related information and to collaboratively work on it. In such a scenario, today’s available collaboration support applications, e.g. enterprise collaboration systems like wikis, either sacrifice end-user experience or semantic richness when dealing with structured knowledge. The presented collaborative task management (TM) application circumvents this trade-off by showing how the Kasimir TM client and the Collaborilla collaboration server interact closely. The TM client supports the KWer’s personal TM and incorporates collaborative tasks. It invokes the collaboration server which centrally manages the collaborative tasks. It implements elaborated methods for metadata sharing and collaborative editing of this shared metadata. We present the detailed proposal for an underlying architecture of the application, review related work and conclude this paper by pointing out future work.

Abstract [en]

This thesis is driven by the motivation to explore a way of working collaboratively that closely reflects the World Wide Web (WWW), more specifically the potential of the Web architecture built on Semantic Web technologies and Linked Data. The goal is to describe a generic approach and architecture that satisfies the needs for loose collaboration and collective knowledge construction as exemplified by the applications described in this thesis. This thesis focuses on a contribution-centric architecture which allows for flexible applications that support loose forms of collaboration.

The first research question deals with how Web-based collective knowledge construction can be supported. The second research question explores the characteristics of collective knowledge construction with respect to the Open World Assumption (OWA). The OWA implies that complete knowledge about a subject cannot be assumed at any time, which is one of the most fundamental properties of the WWW. The third research question investigates how Semantic Web technologies be used in order to support such a contribution-centric architecture.

The thesis and its underlying publications are of a technical character and are always grounded in theoretical models and considerations that have led to functional implementations. The research has evolved in iterative development processes and was explicitly directed at building applications that can be used in collaborative settings and that are based on standardized Web technologies. One of the main outcomes, an information model, was developed together with such an application and provides a number of novel approaches in the context in which it was designed.

The validity of the presented research is supported by evaluations from different perspectives: a list of implemented applications and showcases, results from structured interviews that have investigated the suitability for various resource annotation processes, as well as scalability aspects.

The thesis concludes that it is ultimately up to the application how "loose" the collaboration should be and to which extent the OWA is incorporated. The presented architecture provides a toolkit to support the development of loosely collaborative applications. The showcased applications allow the construction of collaborative conceptual models and to collaboratively annotate educational resources. They show the potential of the used technology stack and the introduced contribution-centric architecture that sits on top if it.
