Just for fun, how could I go about creating a navigable tag tree based on Stack Overflow?

It would be interesting to see the following somehow:

  • Which technologies generate the most problems?
  • Which technologies' questions are the most answered?
  • Which technologies have the most helpful users (highest rep), and get answered most quickly?
  • When is the best time of the week to ask questions for a given technology?

  • Belongs on meta...

  • I was thinking it would also be fun to know some statistics based on the ip addresses e.g. which country/region posts most about C++, C# etc. :-)

  • <dunce hat>Is this something I need to do? i.e. raise it as a question on meta-stackoverflow? or is there a way of moving it over? Nov 13, 2009 at 14:55
  • based on this, am flagging meta.stackexchange.com/questions/2683/… Nov 13, 2009 at 15:18

You could first try creating a query at StatOverflow which uses a data dump of the whole site. Here is a link to the schema for that site.

If you want to roll your own.. I would start your work by getting your own copy of the Stackoverflow Data Dump:

This is a dump of all of the useful information about the site up to Nov09.
