 guido perhaps more useful would be if tim could check in the pickle s generated by one of his training runs so that others can see how tim s training data performs against their own corpora i did that yesterday but seems like nobody bit just in case wink i uploaded a new version just now since mincount went away unknown_spamprob is much less likely and there s almost nothing that can be pruned away so the file is about NUMBERx larger now URL this could also be the starting point for a self contained distribution you ve got to start with something and training with python list data seems just as good as anything else the only way to know anything here is for someone to try it
