Purposes of processing
www.kde.cs.uni-kassel.de is run by the Knowledge and Data Engineering team of the University of Kassel as a research project.
In order to carry out the research, www.kde.cs.uni-kassel.de collects more data of its users and analyzes it in a greater extend than commercial web applications would do. The information is being used to provide and improve recommendation services, spam detection or ranking functions and also for the design of privacy aspects in bookmarking systems. Results can later be applied to other web 2.0 applications. Since science is an open process the options for the data’s usage can not be finalized or completed. For www.kde.cs.uni-kassel.de, however, there is no interest in the real person behind the userprofile. The information will not be used for advertising. www.kde.cs.uni-kassel.de will not give information about the user to third parties. The only exception to this rule are other research groups, which can achieve a part of the data set, and use it for their own research and to revise the findings of the www.kde.cs.uni-kassel.de project.
This data is made pseudonymous though.
