open source data mining tools

[May 1 :  I decided to keep updating the original list of tools I posted below on a page here]

This was my first blog post on Data-mi.ning.com.  Ning.com was very usable and there are great resources available on this social network.

I was at the Semantic Web Meetup @ the Hearst Building in NYC (amazing venue, the first green building completed in NYC) yesterday and someone asked about open source tools available for data mining, specifically for clustering. Unfortunately I had to run out after the meetup and couldn’t provide these to him. The one mentioned by the presenter was Weka, which also the first free open source tool I came across.

Anyway, here are the ones I have found that are worth checking out and I’m sure there are others and more to come.

These 4 have GUIs for us non-programmers.

Use at your own risk! I cannot speak to the accuracy of the algorithms although many of them seem to be well established in the field. There are really 2 issues here – you have to be concerned not only about the underlying algorithm being used but also how effectively and accurately it was translated into code. Nevertheless these seem like solid apps…

I have removed the links to the apps from this post and point you the updated list that now lives on it’s own page here.
