Forward Chaining
Definition
Forward chaining derives further conclusions from known facts using rules.
A rule-based procedure that starts from existing facts and repeatedly applies applicable rules until a goal or fixed point is reached.
Simply explained
The system begins with what it knows. Matching if-then rules provide further results step by step.
Why it matters in practice
The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.
Example from business
A rule engine derives verification and approval steps from order data.
Limits and pitfalls
- Cycles, contradictory rules, and rule order can cause explosions or unexpected results.
Origin & history
Forward chaining has been established in production rule systems and expert systems.
Use in mid-sized companies
- Possible example: A rule engine derives verification and approval steps from order data.
