Questions About Example Part_3_2_Extracting_Diseases_from_Electronic_Health_Records.ipynb

[JBarsotti]

This is an amazing module. Thanks for all your hard work.

I was working through the notebook notebooks/introductory/Part_3_2_Extracting_Diseases_from_Electronic_Health_Records.ipynb, and I have a couple of questions:

1. Why do we need to retrain the modelpack on our own personal? I've tried it without retraining, and it seems to work okay, still. Am I missing something?
2. I have access to the entire UMLS database. I tried to use that as my medpack model, but it doesn't seem to work with the code in notebooks/introductory/Part_3_2_Extracting_Diseases_from_Electronic_Health_Records.ipynb. Even on the simple example "This patient suffers from diabetes," it isn't able to recognize diabetes as an entity. When I run it on large clinical notes, it does not return a lot of CUIs that map to preferred names. They are just listed as "Unknown." Any ideas?

Thanks for an awesome module! It really is great.
