[Haskell-cafe] Subcategories on Hackage

[Paolino]

I think there are two reasons to browse the hackage database.

First reason reflects the common need to find a library that suites one's
needs. In this case it's very easy to find it with google adding "hackage"
"haskell" to the submitted word list.

Second reason is to have a nice landscape of packages when one enters the
site.
For the second reason, which is real browsing, categories are a pain,
whoever and however they are done. The more they are correct , the more they
are difficult to understand. The more they are easy like tags the more it's
difficult to put them in a hierarchy.
One well known solution is to put tags in a high dimensional space where the
tag names and distance between tags is defined by statistics on the tags
cloud of each tag holder (packages). In this case browsing is jumping from
one tag to another *near* one in the tag space and see the packages *around*
, while inserting new packages changes the position of the tags in their
space.
An easiest , but somewhat wrong, solution is give each tag a dimension and
have the packages in the space to browse.

Ontologies are more on formalising the meaning (seen as interrelations) of
concepts, which tags are not, and I don't think even software categories
are. But this is really debatable.

my 2 cents
