We explore on the German Wikipedia whether only the mere number of contributors makes the difference or whether the high quality of featured articles results from having experienced authors contributing with a reputation for high quality contributions. Expand

This paper presents quantitative and qualitative representations of locomotion and algorithms to deal with them in a semi-autonomous wheelchair. Expand

We propose pixel-oriented network visualization (PONV), a new visualization for social networks changing in time. Expand

Focusing on observable message signs and referencing structures, communication processes can be described and analysed as message reference networks which are characterized by dynamic pattern evolution. Expand

We propose a generalization algorithm that abstracts from irrelevant details of a course of motion in order to represent the coarse structure qualitatively. Expand

The analysis and modelling of processes involved in motion perception is the aim of our interdisciplinary cooperation between psychophysics and computer science 3. Expand

We present a framework for mobile intention recognition that covers all levels, from low-level position data to high-level intentions, with the detailed structure of the motion track as an intermediate level. Expand

Ein wesentlicher Schritt in der Verarbeitung von Bewegungsverlaufen ist deren Generalisierung (Vereinfachung und Glattung) in unterschiedlichen Referenzrahmen. Expand

In qualitative motion representation, frames of reference play an important role as well in measuring of the motion data as in representation and application. Expand
