Great work. It might be a good idea to add usage instructions to the GitHub readme. A few questions:

— Are you releasing the dataset? Is there any place I can get more details about the dataset? I'd love to see how well a simple RNNLM does.

— Is it an end-to-end pipeline? As in, if I have a SE question url or text, can I just pass that in and it'll automatically do all the preprocessing and give me the predicted tag?

— Is the trained model available somewhere?
