I am trying to classify text documents using a huge corpora. Thats a huge tagset (more than 1000 tags). Corpus will have 1000 samples for each tag. But the tagset is not closed. New tags can be added in future as per the text content. There will be human intervention in between where I can get new tags if the situation arise. There can be multiple tags per text document.
Is it possible via some already implemented toolkit in python/ R/ C/ Java? If not I guess it is a problem of semi-supervised learning. I am familiar with nltk as well as scikit classifiers. Can those functions be used with other reinforcement learning toolkit?
I have no experience with reinforcement/ semi-supervised learning. I hope I am clear in the question. I will be thankful for your suggestions.
