I received the following notice today from the Qualitative Research for the Human Sciences Discussion List. I’m not familiar with this analysis tool and would appreciate receiving feedback from others. Their website requires registration but is free to users as a beta version: http://pcat.qdap.net/

The Public Comment Analysis Toolkit (PCAT) is Web-based, university-hosted
software engineered for the specific task of reviewing public comments
submitted via the Federal Docket Management System. PCAT is actually version
2.0 of the Coding Analysis Toolkit (CAT), therefore it is also useful for
sorting all kinds of CAT-style ‘text’ datasets.

If you have lots of digitized text, you can form a team of peers, create a
project, upload data, discover important themes and issues, and organize
your analysis with PCAT. This system is the end product of ten years of
NSF-funded public comment classification work by Dr. Stuart W. Shulman, who
has published numerous peer-reviewed papers on the subject.
