This tutorial provides a comprehensive guide to grammar extraction using Grex, from the theoretical foundations to its practical application.

First, we will provide a comprehensive overview of the methodology, covering its scope and limitations. Then, we will offer a practical guide to the tool’s capabilities and implementation.

The following key topics will be covered in order:

• Fundamentals: What treebanks are (the required data), the concept of a grammar rule and its formal definition.

• Rule extraction definition: How to operationalise the extraction of grammar rules using Grex through a YAML file

• Feature space: How to define the feature space which may be possible predictors or triggers of a rule.

• Running Grex: How to execute the extraction process.

• Interpreting results: How to understand and analyse the Grex’s output.
