Link parkin': Two text mining toolkits:
The Lemur Toolkit is a open-source toolkit designed to facilitate research in language modeling and information retrieval. Lemur supports a wide range of industrial and research language applications such as ad-hoc retrieval, site-search, and text mining.
LingPipe is a suite of Java libraries for the linguistic analysis of human language.
Lemur is bleeding edge research grade stuff, while LingPipe is a stable commercial product.
