Persönliches WissensmanagementAbstract aus dem Text: As social tagging applications continuously gain in popularity, it becomes more and more accepted that models and tools for (re-)organizing tags are needed. Some first approaches are already practically implemented. Recently, activities to edit and organize tags have been described as “tag gardening”. We discuss different ways to subsequently revise and reedit tags and thus introduce different “gardening activities”; among them models that allow gradually adding semantic structures to folksonomies and/or that combine them with more complex forms of knowledge organization systems. Moreover, power tags are introduced as tag gardening candidates and the personal tag repository TagCare is presented.

The Risks of Visualization. A Classification of Disadvantages Associated with Graphic Representations of Information
In this paper, we review and classify the disadvantages and risks associated with the use of visual representations of information. We complement a review of literature with expert interviews and focus group results on the practical negative experiences with the use of visual representations of information. Based on these two sources, we distinguish between social, cognitive, and emotional risks of visualization that can be viewed from two perspectives: from the point of view of the user and from the point of view of the designer of a graphic representation. We discuss implications of the identified disadvantages and ways of overcoming or avoiding them. The paper concludes by providing an outlook on overlooked or emergent risks of visualization.
