Concept maps similarity measures for educational applications

Concept maps represent a signicant tool in education, used to plan and guide learning activities and to help teachers in some en- deavors such as analyzing and rening their teaching strategies, retriev- ing suitable learning material, and supporting the provision of adaptive guidance in adaptive learning environments. Here we propose seven mea- sures of similarity among concept maps, representing course modules. They deal with both structural and didactic aspects of the maps, to find out educational similarities among their associated course modules. The performance of the proposed similarity measures are analyzed and evaluated by means of some significant case studies.
