Knowledge Representation in AI

Which of the following is NOT a type of knowledge representation?

• Semantic networks

• Frames

• Flowcharts

• Production rules

Which logic is commonly used in AI for knowledge representation?

• Boolean logic

• Predicate logic

• Fuzzy logic

• Modal logic

Predicate logic uses:

• Only constants

• Only variables

• Predicates and quantifiers

• Graphs

What does the predicate in predicate logic represent?

• A mathematical function

• A relationship

• A memory location

• An algorithm

In predicate logic, the expression ∀x P(x) means:

• There exists x such that P(x)

• For all x, P(x) holds true

• P(x) is false

• P is undefined

Which of these is an example of declarative knowledge?

• How to ride a bike

• Steps to open a file

• Paris is the capital of France

• Debugging a program

Which method is commonly used to represent facts and rules in AI?

• Heuristics

• Knowledge graphs

• Production systems

• Neural networks

Which of the following is a disadvantage of predicate logic?

• Too simple

• Not expressive

• Computationally expensive

• Cannot represent variables

Which one is a valid rule-based representation?

• IF A AND B THEN C

• FOR x DO y

• BEGIN END

• LOOP UNTIL

Which of these is used in rule-based systems?

• IF-THEN rules

• While loops

• Object-oriented inheritance

• Hash tables
