Various types of relationships may be defined using semantic networks. The two most common types of relationships are • –IS-A (Inheritance relation) • –HAS (Ownership relation) Semantic networks(Cont..) • Let’s consider an example semantic network to demonstrate how knowledge in a semantic network can be used.

Semantic networks Knowledge Representation. Network Operation • To infer new information from semantic networks, we can ask questions from nodes. • Ask node vehicle: ‘How do you travel?’ – This node looks at arc and replies: road - Asks node Car (because of IS-A relationship) – Asks node Vehicle (IS-A relationship) – Node Vehicle Replies: road Semantic networks(Cont..) Problems with Semantic Networks • Semantic networks are computationally expensive at run-time as we n...
