FYI: Cluster Analysis Program, Parser Guide Web Site
I have just been recommended a cluster analysis program developed by Sawtooth but available in Europe from their distributor, SKIM products, both are available on the internet and demo disks are also available.
SPSS also contains a cluster analysis element, though this is no considered to be as easy to use as the Sawtooth product.
Karen Smith, an employee here at Ergo, has put together a very nice web based guided tour of the parsers of the world which makes it easy to find and try all the different parsers of the world. It is also a very convenient way to compare parsers and make notes about their various strong and weak points. The site also contains a section with sample sentences chosen from the domain of practical applications and a set of standards for evaluating parsers. Both are available at http://www.ergo-ling.com. The parser tour is under the heading "Parsers of the World" and the sample sentences and standards are under "Parsing Contest".
I highly recomend this site for anyone with an interest in NLP.
