Abstract [en]

This paper describes an approach for collaborative construction of artifacts, such as e.g. graphical maps and annotatable text documents, without requiring write-access to a common single file. Our approach is applicable to any kind of artifacts that can be divided into separate contributions, where each one is authored and stored independently, and, on request, merged into the artifact. The goal is to move collaboration issues from the files where artifacts are expressed, to an information directory. This information directory manages information around artifacts and keeps track of existing contributions to artifacts. Our prototype of such an information directory, named Collaborilla, is designed to be a flexible service, which can be updated by anyone in a wiki-style manner. With this approach, viewing a collaboratively constructed artifact gives each viewer the control of including or excluding various contributions. Moreover, each viewer can easily choose to participate and provide a new contribution to the artifact without the other authors being aware of this. If information about this new contribution is published in the Collaborilla directory, the contribution will also be seen by others.

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.
