# NOTE

The concept codes from all terminologies were replaced by the tuple **UMLS CUI, AUI**.

We recommend parsing them to the terminology code.

To do so, take the CUI and the AUI when searching for the appropriate code.

# Prediction

The columns ```Has_evolved``` and ```generic_change``` were used as target for predicting the evolution.

The column ```Version``` was used only as reference to compute the features. It must be discarded when predicting the evolution.
