Looking for a simple tutorial on how to fine tune a model for relation extraction

Hi,

I have a relation extraction task I’m working on:
My goal is to extract from free text sentences the relation: work_for.

For example the sentence:
Andy Jassy is the chief executive officer of Amazon.
will extract: work_for(Andy Jassy, Amazon)

I’m looking for a guide on how to fine tune a model to get this output but to no avail, also looked at the tutorial course here but it does not provide enough detail so I can fine tune REBEL for instance or other models that might be suitable.
Can anyone please assist?

Thanks!
