Where Are The Semantics In The Semantic Web? / quote 16 of 29
Four kinds of semantics
We ask three questions about how semantics may be specified: 1. Are the semantics explicit or implicit? 2. Are the semantics expressed informally or formally? 3. Are the semantics intended for human processing, or machine processing? These give rise to four kinds of semantics: 1. Implicit; 2. Explicit and informal; 3. Explicit and formal for human processing; 4. Explicit and formal for machine processing.
