Open Source Search Results Clustering Framework

My smart search buddies over at BA-Insight (who need to get their blog online!) pointed me to Carrot2, which is described as “ a system for clustering textual data“. (the site is a bit slow)

Generally speaking, Carrot2 is an Open Source alternative to Vivisimo. (Nice!)

Carrot2 has some other interesting features too. Like for example, it can be used as a meta-search component. In addition, it can be integrated with full-featured text search engines such as the Open Source Egothor and some other lesser known engines.

Overall I’m impresses with the various clustering algorithms you can select to display your results. Performance however seems to be lagging, but I’m sure that can be worked out.
