Frequently Used Terms
- Axioms are propositions that are assumed to be true, axioms do not require further proof of truth. Example: For all real numbers x and y, x + y = y + x (commutative law of addition) applies.
- Inference Process is a process used in expert systems to produce new information obtained from previously known information. In expert systems, the inference process is carried out in a module called the Inference Engine.
- Propositional Connective (Statement Connector) is a connecting word used to combine two or more necessary propositions. Examples of Propositional Connective Notations or Symbols are as follows.
| English Name | Connective Name | Symbol |
|----------------------|-----------------|--------|
| Conjunction | AND | ? |
| Disjunction | OR | V |
| Negation | NOT | ~ |
| Material Implication | If-Then | ? |
| Material Equivalence | Equals | ? |
