Reasoning as Data: Representation-Computation Unity and Its Implementation in a Domain-Algebraic Inference Engine

Chao Li, Yuru Wang · 2026

Every existing knowledge system separates storage from computation. We show this separation is unnecessary and eliminate it. In a standard triple is_a(Apple, Company), domain context lives in the quer…
