Both terms concept maps ("Εννοιολογικοί χάρτες" in Greek) and mind maps ("Νοητικοί χάρτες" ή "Χάρτες Εννοιών" in Greek)used in Europe in a form of semantic network.
Concept mapping is used more general.
The difference between concept maps and mind maps is that a mind map has only one main concept, while a concept map may have several.
A mind map can be represented as a tree, while a concept map may need a network representation.
The IHMC CmapTools program http://cmap.ihmc.us)is one of the most popular software in Europe for concept mapping.
