CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Rule-based expert systems are expert systems in which the knowledge is represented by production rules. A production rule, or simply a rule, consists of an IF part (a condition or premise) and a THEN part (an action or conclusion). IF condition THEN action (conclusion).

Detailed explanation-2: -Productions consist of two parts: a sensory precondition (or “IF” statement) and an action (or “THEN"). If a production’s precondition matches the current state of the world, then the production is said to be triggered. If a production’s action is executed, it is said to have fired.

Detailed explanation-3: -The aim of the expert system is to take knowledge from a human expert and convert this into a number of hardcoded rules to apply to the input data. In their most basic form, the rules are commonly conditional statements (if a, then do x, else if b, then do y).

Detailed explanation-4: -An expert system generally consists of four components: a knowledge base, the search or inference system, a knowledge acquisition system, and the user interface or communication system.

Detailed explanation-5: -A classic example of a rule-based system is the domain-specific expert system that uses rules to make deductions or choices. For example, an expert system might help a doctor choose the correct diagnosis based on a cluster of symptoms, or select tactical moves to play a game.
