## Glossary## Index## N## Index## Node## ContextA term used in graph theory. ## DefinitionA ## In CG theoryIn conceptual graph-theory, the nodes are of two types: ## Other examplesOther examples of nodes include: - The cities in a graph denoting a map of roads (the roads are the arcs).
- The intersections of roads in a graph representing the map of a city (the roads are the arcs).
- The hosts (servers and clients) in a graph denoting a computer network, such as the internet (the network links between them are the arcs).
- The constituents in a phrase-structure-tree representing a sentence, such as "NP", "VP", "S", "PP", etc. (The lines between the constituents are the arcs).
- The types in a type hierarchy-lattice (the "subtype relation" links are the arcs).
