Parameters¶
PyGraft allows for a broad range of user-specified parameters. Overall, these can be seen split into:
general parameters, seen as metadata for the generation process
schema parameters, governing the number of classes, relations, and how they are expected to interact
KG parameters, governing the number of triples, instances, and how the latter should populate the schema
All these parameters can be freely modified in the json and yaml configuration files provided as templates.
For a quick example on how you can fetch the template in the current corkind directory and modify the parameters manually, see the Advanced Usage section.
