Introduction
I received my PhD from the Technische Universität Dresden for my work in the field of knowledge visualization. Besides knowledge graphs, semantic technologies, graphics and visualization, my interests include open data and open science. My work at the Saxon State and University Library embraced fields such as research data management and building up the local Service Center Research Data. I see new technologies as a promising tool to help solve today's problems, such as information overload, lost trust in facts, and the resulting environmental and social challenges. My interest in scientific facts also includes the domain of physiotherapy and I'm looking for partners from this field. Currently, I'm working as a freelancer (softwaredevelopment and visualization).

The Dresden Open Software Toolbox (DropsBox) is a software modelling toolbox consisting of a set of open source tools developed by the Software Technology Group at TU Dresden. The DropsBox is built on top of the Eclipse Platform and the Eclipse Modeling Framework. The DropsBox contributes to the development and application of domain-specific langua...

Durch die stetig wachsende Datenflut wird es zunehmend schwerer, interessante Informationen zu erkennen, diese richtig zu interpretieren und letztlich Erkenntnisse zu gewinnen. Durch den Einsatz von Visualisierungswerkzeugen kann dieser Prozess erheblich verbessert werden. Jedoch adressieren aktuelle Anwendungen vor allem den Experten. Um auch Enda...

Information on how to visualize RDF data is stored differently by each visualization tool to date. We propose the RDFS/OWL Visualization Language (RVL), a declarative language for sharing visualization settings as simple as CSS styles. The mapping definitions can be given a URI and shared along with the data to be visualized, they can be composed,...

Interactive visual analytic systems can help to solve the problem of identifying relevant information in the growing amount of data. For guiding the user through visualization tasks, these semi-automatic systems need to store and use knowledge of this interdisciplinary domain. Unfortunately, visualisation knowledge stored in one system cannot easil...
Conference Paper
Faceted browsing is a widely spread, intuitive, and interactive search paradigm for information collections based on the metadata of its items. However, it has the problem that every selected criterion is mandatory so that less important ones may reduce the result set and interesting items may be removed unintentionally. On the other hand, choosing...

Although many terminologies, taxonomies and also first ontologies for visualization have been suggested, there is still no unified and formal knowledge representation including the various fields of this interdisciplinary do- main. We moved a step towards such an ontology by systematically reviewing existing models and classifications, identifying...
Conference Paper
Full-text available
Reuse is an important means of reducing costs and effort during the development of complex software systems. A major challenge is to find suitable components in a large library with reasonable effort. This becomes even harder in today’s development practice where a variety of artefacts such as models and documents play an equally important role as...
Conference Paper
Full-text available
Faceted Browsing, also known as Faceted Search, recently became a popular interface paradigm and is used as a visual selection mechanism to browse data collections. It is particularly suitable for structured, but heterogeneous data with explicit semantics. As the amount of this data will grow in respect to a rising Semantic Web, it is worth looking...

Question
Was Jock D. Mackinlays "Ranking of perceptual tasks" [1] (Fig. 15, p. 125) empirically verified by now? At the time of writing (1986) it was not, as stated by the author. Kamps also states in 2012 that Mackinlay "never evaluated his task ranking empirically" [2], but possibly/probably he or someone else did by now. Is there a very similar ranking that was evaluated? I'm aware that many other related empirical studies have been done in this field since then, but would someone recommend a study that I shouldn't miss by no means in this specific context?
