2.3.1 Knowledge Domain Representation Using a Fuzzy
Related-Concept Network
A Fuzzy Related-Concepts Network is a network of concepts, which depicts,
also, the knowledge dependencies that exist between the domain concepts of the
learning material. Therefore, it illustrates so the structure of the learning mate-
rial, as the concepts' knowledge dependencies. Particularly, it represents the
fact that the knowledge level of a domain concept is increased when the knowl-
edge level of a related topic improves, as well as the fact that the knowledge
level of a domain concept is decreased when the knowledge level of a depended
topic is not satisfactory. The Fuzzy Related-Concepts Network (Fig. 2.10 ) con-
sists of: nodes, which depict the domain concepts of the learning material, and
directed arcs, which represent relations between the concepts of the learning
material.
The relations that exist between the concepts of the learning material depict
so the order in which the domain concepts have to be delivered and the struc-
ture of the learning material, as the knowledge dependencies. In particular, there
are three type of relations between the concepts: “precedes” that declares the
order in which each domain concept of the learning material has to be taught
