Question

In Artificial Intelligence , a semantic network

• A. Is a graph-based method of knowledge representation where nodes represent concepts and arcs represent relations between concepts.
• B. Is a graph-based method of knowledge representation where nodes represent relations between concepts and arcs represent concepts.
• C. Represents an entity as a set of slots and associated rules.
• D. Is a subset of first-order logic.

Comments

It is a knowledge representation technique that uses nodes to denote a concept and the arcs to show the relationship between the concepts.

A sentence which we use in our daily life may be represented by semantic net knowledge representation.

Hence , A) is the correct option.

Answer 1

ans is A 

A semantic network, or frame network, is a network that represents semantic relations between concepts. This is often used as a form of knowledge representation. It is a directed or undirected graph consisting of vertices, which represent concepts, and edges, which represent semantic relations between concepts.^[1]
