Definition
Commonsense knowledge refers to the vast amount of implicit information about everyday life, physics, social norms, and cause-and-effect relationships that humans acquire naturally. In AI, acquiring this type of knowledge is a significant challenge because it is rarely explicitly stated in training data yet crucial for reasoning. Systems lacking commonsense may fail at simple tasks like understanding that a glass will break if dropped. Projects like ConceptNet and ATOMIC aim to encode these facts to help AI systems interpret context, infer intentions, and make logical deductions similar to human intuition.
