Semantic Networks

Expanding the network
You can easily expand a semantic network by simply adding nodes and linking them to their related nodes currently in the network

A simple representation scheme which uses a graph of labeled nodes and labeled directed arcs to encode knowledge
- Nodes: objects, concepts, actions or events in the world
- Arcs: relationships between nodes
