Two-Pass AI Extraction Lab (GraphBaby Architecture) WebLLM Pattern

Compare unconstrained extraction (prone to schema bloat & hallucination) against two-pass schema-grounded extraction.

Pass 1: Schema Blueprint Generation (TBox) Prompt: OWL Class Hierarchy Designer

            Identified Classes: Person, Doctor, Cardiologist, Medication, Disease, Organization.

            Axioms: Cardiologist ⊑ Doctor ⊑ Person. treats(Medication, Disease).

Pass 2: Schema-Bound Individual Extraction (ABox) Prompt: DO NOT invent classes

            WorksAt(Elena Vance, Metro Heart Clinic); treats(Lisinopril, Hypertension).
