Concept Map (CMap) is a graphical knowledge representation system, which has received growing popularity as a teaching and evaluation tool. In CMaps knowledge is represented by linking concepts to one another and specifying the nature of their relationship on the link.

It allows users to easily create graphical nodes representing concepts, and to connect nodes using lines and linking words to form a network of interrelated propositions that represent knowledge of a topic. The software has been used in classrooms and research labs, and in corporate training.

There are two features of concept maps that are important in the facilitation of creative thinking: the hierarchical structure that is represented in a good map and the ability to search for and characterize new cross-links.
