A semantic network is the most basic structure upon which an identification tree (hereafter referred to as an ID tree) is based.
Semantic networks and frames
Both methodologies- semantic network and frames-can be thought as the precursors of the actual high-level programming languages, such as C++ or Java, which are fundamentally object-oriented languages.
Semantic network Represents information (such as the meaning of an English sentence) as a set of nodes representing objects, concepts, or events and directed labelled arcs representing the relationships between pairs of nodes.
Semantic Network. A method of representing structured knowledge. It consists of nodes and links, where the nodes are concepts or entities and the links represent relationships and associations among the concepts.
Semantic Networks: However, when we need to describe more details, such as the relations between an object's parts, it may be better to use the kinds of 'semantic networks' we saw in §4-6 to represent a person's self-model, ...
semantic network a representation of meaning based on a network of nodes that represent objects and labeled arcs between nodes that represent relations between the objects denoted by the nodes.
Semantic network allows a common form of inference known as inverse links. For example we can have a HasSister link which is the inverse of SisterOf link.
