What is Concept Mapping ?
Concept mapping is a technique for representing knowledge in graphs. Knowledge graphs are networks of concepts. Networks consist of nodes (points/vertices) and links (arcs/edges). Nodes represent concepts and links represent the relations between concepts.

Concepts and sometimes links are labeled. Links can be non-, uni- or bi-directional. Concepts and links may be categorised, they can be simply associative, specified or divided in categories such as causal or temporal relations.

Concept mapping can be done for for several purposes:

    * to generate ideas (brain storming, etc.);
    * to design a complex structure (long texts, hypermedia, large web sites, etc.);
    * to communicate complex ideas;
    * to aid learning by explicitly integrating new and old knowledge;
    * to assess understanding or diagnose misunderstanding.
