2) In AI systems, Knowledge can be represented in two ways. What are these two ways?
- Machine Logic
- Predicate Logic
- Propositional Logic
- Compound Logic
Options:
- i. and ii.
- i. and iii.
- ii. and iii.
- iii. and iv.
Correct answer: 3
ii. and iii.
In an intelligent agent, the knowledge can be represented in two ways:
- Propositional logic and
- Predicate logic
3) Which of the mentioned point are not valid with respect to a Propositional Logic?
- In propositional Logic, each sentence is a declarative sentence
- In propositional logic, the sentence can have answers other than True or False
- Propositional Logic is a type of knowledge representation in AI
- None of the above
Correct answer: 3
In propositional logic, the sentence can have answers other than True or False
In propositional logic, each sentence is a declarative sentence which is a sentence or proposition which is either true or false.
4) Consider the following statement:
"In the propositional logic system of knowledge representation, it is assumed that the word contains object, relations, and functions. The Predicate logic is a symbolized reasoning in which we can divide the sentence into a well-defined subject and predicate."
By reading the above statement, State whether it is true or false?
- True
- False
Correct answer: 2
False
The given statement is false because it is not what a propositional Logic is. The given statement holds for Predicate logic.
5) What does a first order predicate logic contain?
- Predicate and a subject
- Predicate and a Preposition
- Subject and an object
- None of the above
Correct answer: 1
Predicate and a subject
The Predicate logic is a symbolized reasoning in which we can divide the sentence into a well-defined subject and predicate. The subject is defined by the predicate. It should be noted that the predicate can only refer to a single subject.
