### Data pre-processing
The organisers of [IWPT20 shared task](https://universaldependencies.org/iwpt20/data.html) distributed the data sets and a data pre-processing script `enhanced_collapse_empty_nodes.pl`. If you wish to train a model on IWPT20 data, apply this script to the training and validation data sets, before training the COMBO EUD model.
The script is part of the [UD tools repository](https://github.com/UniversalDependencies/tools/).
