Wir hören einen Vortrag von

    Patrick Oesterling

mit dem Titel

    "Visual Analysis Of Information Spaces
    Using Topological Landscapes"


Zum Inhalt:

Document collections are constantly increasing in size and 
complexity, thus asserting themselves as the main information 
source. While one can achieve insight to the data by applying well 
known techniques like clustering, wavelet analysis or projection to 
reduced dimensions (PCA, MDS etc), we tackle this problem from the 
topological point of view by defining an information space as a set 
of documents and a topology on this set. Using the fact, that 
humans are naturally trained in understanding the structure of a 
terrain, we visualize the topology of this high dimensional space 
by means of "Topological Landscapes", a new metaphor that was 
recently introduced to the community by Gunter Weber et al. We 
therefore present a multiple-stage process to obtain a decomposed 
contour tree which can directly be mapped to a 3D terrain with the 
same topology as the given dataset.

Der Vortrag wird in Deutsch gehalten.
