manage a plurality of drawings as a tree structure representing a parent-child relationship between the plurality of drawings; and

trace the tree structure and extract a characteristic term from a subject drawing and a parent drawing of the subject drawing as a characteristic of the subject drawing.

12. The drawing management apparatus according to claim 8 , wherein the processor is configured to:

manage a plurality of drawings as a tree structure representing a parent-child relationship between the plurality of drawings; and

trace the tree structure and extract a characteristic term from a subject drawing and a parent drawing of the subject drawing as a characteristic of the subject drawing.

13. The drawing management apparatus according to claim 9 , wherein the processor is configured to:

manage a plurality of drawings as a tree structure representing a parent-child relationship between the plurality of drawings; and

trace the tree structure and extract a characteristic term from a subject drawing and a parent drawing of the subject drawing as a characteristic of the subject drawing.

14. The drawing management apparatus according to claim 10 , wherein the processor is configured to:

manage a plurality of drawings as a tree structure representing a parent-child relationship between the plurality of drawings; and

trace the tree structure and extract a characteristic term from a subject drawing and a parent drawing of the subject drawing as a characteristic of the subject drawing.

15. The drawing management apparatus according to claim 7 , wherein the processor is configured to extract the characteristic term from the name of the drawing.

16. A drawing management system comprising:

a drawing management apparatus that manages a plurality of drawings; and

a drawing storage apparatus that stores the plurality of drawings,

the drawing management apparatus including

an input device; and

a processor configured to

extract a characteristic term of a drawing as a characteristic of the drawing,
