An early expert system that used rules to infer molecule structures.
DENDRAL was a crime lab for molecules. It read a molecule’s lab fingerprint and drew the suspect.
Chemists used it to work out molecule structures. It helped start expert systems and rule-based knowledge in AI.
Expert System
DENDRAL was an early landmark case for expert systems.
Symbolic AI
DENDRAL used clear rules and search, not neural networks.
KR
Chemistry knowledge was written as rules for the program to reason with.
MYCIN
MYCIN carried on the same expert-system style.
