Future Network Architectures Section 1 Section 2 Section 3 Section 4 Section 5 Section 6 Section 7 Section 8 | Semantic, Context, Naming and Routing Semantic Web "Semantics is the technical term used to refer to the study of meaning, and since meaning is a part of language, semantics is a part of linguistics. “ Semantic Web is not about links. Semantic Web describes the relationships between things (like A is a part of B and Y is a member of Z) and the properties of things (like size, weight, age, and price).
