concept map of biomolecules drawn using principled approach using just 2
relation types (knowledge organizers).

Drawing concept map following the principled/logical ap-
proach

A principled or a logical approach is based on the grammar of scientific
knowledge. We can draw principled or logical based concept maps (using
the KR approach) which are different from the concept maps influenced by
Novak.

Figure 4, shows a principled concept map on organic molecules gener-
ated from our knowledge base. The concept map depict the minimal set of
knowledge organizers i.e. relation types for representing the biomolecules.
It is possible to represent some of the knowledge about organic molecules
with using just two relation types i.e. semantic relations (knowledge orga-
nizers) as depicted in the figure. We intend to develop a set of such knowl-
