1. Introduction into digital knowledge maps
Knowledge maps also known as cognitive maps are graphical representationsin which idears or words are
placed in so called nodes. These are connected with lines that can indicate uni-or bilateral directions (through
arrows), which are called vectors. Linking words can be added to the vectors to show the interrelationship
between various nodes.
In this paper, the term of knowledge maps will be used to collectively refer to both mind maps and
concept maps.they can be either constructed manualy (with paper and pen), digitally (on a desktop computer,
netbook, tablet), indiviudally, in pairs or collaboratively in smalle or large groups.
Mind maps use a central word, idea or other item and arrange others intuitively around the
