Symbolic AI

Also known as: GOFAI, Rule-based AI

AI built from explicit symbols, logic and hand-written rules rather than learned statistical patterns.

What Symbolic AI is

Symbolic systems represent knowledge in a form humans can read and edit: ontologies, knowledge graphs, production rules and logical inference.

How it works

An inference engine applies rules to facts to derive conclusions. Knowledge must be authored by experts, which is precise but slow to build and brittle at the edges.

Why it matters

It dominated early AI, still runs in compliance and configuration engines, and is returning in neuro-symbolic designs where a language model calls a deterministic reasoner.

Common uses

→Regulatory compliance engines
→Knowledge graphs
→Expert configuration systems
→Constraint solvers

Strengths

✓Transparent and auditable
✓Exact where rules apply

Watch for

✓Knowledge acquisition bottleneck
✓Fails on ambiguity and noise
