You could look at something like ReadMe (http://gking.harvard.edu/readme) to generate a classifier based on a suitable subsample of your data that then classifies the rest of your data set. Alternatively you could do it the hard way; use a natural language parser to extract all the noun phrases (or just split oout the words), list the unique noun phrases, manually classify all of them using your own criteria to give a pair list (phrase->category), and then match classes back to the rows that contain each noun phrase. ******************************************************************* This email and any attachments are confidential.
