Thanks for the link to montepython. It looks like it might be a good tool for me to learn more about machine learning. As for my citation metadata extractor, once the training data is generated it would be trivial to scale it; there is no shared state. All that is really needed is an implementation of the Viterbi algorithm, & there is one (in pure Python) on the wikipedia page; it is about 20 lines of code. So presumably it could be scaled on the Google app engine pretty easily. But it could be scaled on anything pretty easily; all you need is a load balancer and however many servers are necessary (not many, I would think). best, Erik Hetzner
