I've just been using the opennlp command line cross validator on the small dataset i annotated (along with some eyeballing). It would be cool if there was a standard clinical resource available for this task, but I hadn't considered it much because the data I annotated pulls from multiple datasets and the process of arranging with different institutions to make something like that available would probably be a nightmare.
