Conceptual Dependency originally developed to represent knowledge acquired from Notes
natural language Input.

8.10 Keywords

Conceptual Dependency: It is a model of natural language understanding used in artificial
intelligence systems.
Expert System: An expert system is a computer system that emulates the decision-making ability

Scripts: Scripts are a method of representing procedural knowledge. They are very much like
frames, except the values that fill the slots must be ordered.
