Thanks I will investigate the below thanks Joern. Can someone send me some pointers to the Doc Cat API that I can find? Thanks.

I would like to suggest that we implement doccat format support to train on that data. 3. it would be best so think about how we want to test the doccat component, today we don't have any tests which use lots of data to evaluate it. Probably the sentitment data could solve this for us and a train and evaluate test could be included in the eval tests. +1 to revert and then do these steps after the 1.8.1 release. I can apply my PR myself if nobody objects.

I believe I said something like the pull request was X revision behind and Y revisions ahead. It was not meant to be rude, it was meant to say it is hard to review code when it is so different from the current code base. I am very excited that sentiment analysis is going to be added to OpenNLP, but I have not had time to play with it. If I were to say “great job” before I have add a chance to look at it, it would be flattery not honest praise. > > > > > > > > Let’s clean up the merge. I agree with Chris that scalability and perfection should not be our initial goal. Let’s get something, and we can decide how to optimize later (even if it require a complete rewrite). Perfection is the enemy of the good. > > > > > > > > Finally, because of Chris’ comments it is hard to thank Ana and Chris without sounding insincere. But I’ll try, thank you Chris and Ana. I hope we can get beyond this and that Chris and Ana will continue to improve the performance of the sentiment analysis tool and happily remain part of the OpenNLP family. It is also a good time to toss a big thank you to all of the committers, users, and PMC member. I use OpenNLP almost everyday.
