Some time ago it was proposed to develop trees from the Wikipedia Main
Page, so that one could identify categories based on their propinquity
to main page topics. So for instance, [[highway]] which is linked from
[[transport]] would be classified as [[category:transport]] (pages
could of course have multiple categories, with degrees of separation
from the various main page articles noted, some cut off (number of
degrees away > 5 perhaps, would be used). (e.g. [[category:blah,
degrees:2]]
This function would be automated (or semi-automated), which some may
say is not sufficiently wiki; on the other hand, it would allow us to
come up with a first cut classification for 130000 articles, which will
take a bit of time by hand.
I believe this was done for [[philosophy]]. See [[List of philosophical
topics]]
