Generalized Pythagoras Trees: A Fractal Approach to Hierarchy Visualization
[chapter]
2015
Communications in Computer and Information Science
Preserved Fulltext
An example are binary branching Pythagoras Trees. By stopping the recursion in certain branches, a binary hierarchy can be encoded and visualized. ...
But this binary encoding is an obstacle for representing general hierarchical data such as file systems or phylogenetic trees, which usually branch into more than two subhierarchies. ...
Acknowledgments We would like to thank Kay Nieselt, University of Tübingen, for providing the NCBI taxonomy dataset. ...

The case analysis illustrates the model's capability to generate a qualitative tree from the competency list, where the average accuracy of competency assignment to appropriate parent competency is 72% ...
Therefore, in this paper, we propose a transformation model dedicated to converting the competency list to a competency tree. ...
The codes, or numbering, for each competency were generated; however, they were used just for visualization because codes were not used in the transformation model. ...

We present a novel approach to incremental document maps creation, which relies upon partition of a given collection of documents into a hierarchy of homogeneous groups of documents represented by different ...
To visualize similarity relation between contexts (represented by a set of contextual models), additional "global" map is required. Such a model becomes the root of contextual maps hierarchy. ...
the maximal dissimilarity between two cells Such optimization is based on the generalized Pythagoras theorem: if v 1 , v 2 , v 3 are the edges of a triangle (v 1 + v 2 + v 3 = 0) then |v 3 | 2 = |v 1 ...
