Both the Radial tree and the Phylogenic tree are hierarchical graphical representations created from your data statistics.

The Phylogenic tree displays by proximity the concepts (keywords) of the studied topic. In details, the tree displays the co-occurrence of the 50 strongest concepts (the highest occurrence number). The size of each term is represented more or less big depending on its occurrence (strong or weak).
The aim of this graphical representation is to lead you to point out emerging sub-themes/sub-domains. All tree branches are created with the concepts co-occurrence.
Like in a thesaurus, you can open each leaf to go to matching documents.



The Radial tree is a display mode for thesauri.
The aim of this graphical representation is to give you a global view of your studied content, its repartition. You can conveniently display thesauri made of professional vocabulary or IPC codes.
