# Semantic Networks

Requires a Wolfram Notebook System

Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.

A semantic network represents semantic relations among concepts, two concepts being related if their meanings are related. This is often used as a form of knowledge representation and can be modeled by a directed or undirected graph consisting of vertices that represent concepts and edges joining related concepts. Building a two-step synonym graph for computation with word semantics in *Mathematica* 8 is relatively straightforward using the function WordData, which holds interrelated information on nearly 150,000 words.
