This paper proposes the schema graph for introducing specialization and generalization to a graph-based data model in order to systematize and reuse knowledge effectively. Systematizing and reusing knowledge are important functions of the knowledge-based human activity. The schema graph enables specialization and generalization relationships to be dynamically added, and removed. The methods of modifying these relationships are precisely presented. The schema graph enables us to systematize and reuse knowledge with keeping the structure flexible.
