Visualization of Lucene search results with a treemap
Inspired by these guys who put results from Google into a treemap...
http://google.hivegroup.com/
I did up my own version running against my index of OSS/javadoc trees.
This query for "thread pool" shows it off nicely:
http://www.searchmorph.com/kat/tsearch.jsp?s=thread%20pool&side=300&goal=500
This is the empty search form:
http://www.searchmorph.com/kat/tsearch.jsp
And the weblog entry has a few more links, esp useful if you don't know
what a treemap is:
http://searchmorph.com/weblog/index.php?id=18
Oh: As a start, a treemap is a visualization technique, not
java.util.Treemap. Bigger boxes show a higher score, and x,y location
has no significance.
Enjoy,
Dave

The algorithm is described here;
http://www.cis.hut.fi/research/som-research/book/
A short summary and some sample code is available here:

Some more interesting papers about visualization is available at the
text-mining.org community page.

Happy hacking! :-)

Well the code is very generic - basically 1 method that takes a
Searcher, a Query, the # of cells to show, and the size of the diagram.
Technically I think it would be a Lucene sandbox contribution - but -
for my site I do want to convert the custom spider/cache to use Nutch...
