Le mail de l'auteur :

"Hello,

I have created a chart of Debian software that may interest you.
It is a so called 'Self Organizing Map' visualisation of the dependencies.

It depicts all packages from testing/main with 5 or more dependencies.
Instead of visualizing the dependencies directly, a classification has
been made.

In the chart, all packages that have highly similar dependencies are
grouped close together. Alternatively, packages placed on opposite sides
of the map truly have wildly different dependencies. Clustering is
present at all scales.
Unfortunately, some clusters are too dense to read.

You can view the map at:
http://home.sara.nl/~bram/debchart.jpeg
And the Postscript source at:
http://home.sara.nl/~bram/debchart.ps
Unfortunately, I have no index to the map, but if you know its
dependencies, you should be able to locate a specific package, provided
it has 5+ deps.
Alternatively, you can search in the Postscript source.

For more info on Kohonen's SOM (aka SOFM), search google for
"Kohonen Self Organizing Feature Map"

Yours Sincerely,

Bram Stolk"
