Hi Kyle
This is Prasad from Lead Semantics, I presented 'TextDistil and Fluree' usecase in the webinar you mentioned. Thanks for attending the webinar.
To clarify, the Ontology is specific to the domain and the application for which the extraction is meant for.
Another domain and application would call for another Ontology. (we are not doing open domain extraction - that is not our focus, and there are many solutions to do that!)
TextDistil is designed to work with different Ontologies. If you have an Ontology that is great, then with TextDistil, you only have to map the rest of the pipeline to fit your Ontology (and of course factor in implications of the input text corpus).
In case I am not clear, please feel free to reach out to me.
