What is the correct sequence of steps used by knowledge base designing? A. Ask…

Correct sequence: Choose the task domain or world to represent; Select atoms to represent propositions of interest; Tell the system propositions that are true (axiomatize the domain); Ask questions about the intended interpretation (query the knowledge base).

1. Choose the task domain or world to represent — decide the scope, entities, and aspects you need the knowledge base to cover.

2. Select atoms to represent propositions of interest — define the vocabulary (predicates, constants, propositions) that will express facts about the domain.

3. Tell the system propositions that are true in the intended interpretation (axiomatize the domain) — encode facts and rules using the chosen vocabulary so the knowledge base captures the intended situation.

4. Ask questions about the intended interpretation (query the knowledge base) — use the built knowledge base to answer queries and verify that it supports the intended inferences.

Why this order?

• Defining the domain first ensures you know what needs to be represented.

• Choosing atoms (vocabulary) after that lets you express relevant propositions clearly.

• Axiomatizing uses the chosen vocabulary to capture truths about the domain.

• Querying comes last because queries rely on a defined domain, vocabulary, and axioms.

Common mistakes to avoid:

• Asking questions before the knowledge base is defined — queries will be unclear or unanswerable without a domain and vocabulary.

• Axiomatizing before choosing a proper vocabulary — axioms may be inconsistent or poorly expressed if the vocabulary is not suited to the domain.
