# c4-to-ontology-schema

Amad Zarak
February 21, 2026
Created using `gpt-oss-120b` on h200 sxm
Used 1000 rows of c4 dataset, after cleaning valid json got about 8700 rows.
Planning on using it for structured information extraction

Might refine approach later, but figured others could use this.
Was very hard to find raw text to structured json datasets

The idea here was to generate varied schemas for information extraction purposes
Might have to refine later
