[0090] The present invention will be described in more detail below in conjunction with the accompanying drawings.
[0091] 1. Domain ontology structure
[0092] The present invention formalizes the domain ontology applied to the automatic marking of subjective questions into a five-tuple:
[0093] O={C,A,R,I,SY}
[0094] Taking "Basic Computer Knowledge" subject domain ontology as an example, the definitions and functions of various elements of the domain ontology designed by the present invention and applied to automatic marking of subjective questions will be explained below.
[0095] 1) C represents the collection of all concepts related to a certain field, which defines the subject range of subjective questions. For example:
[0096] C={computer, hardware, arithmetic unit, controller, central processing unit, host, memory, main memory, external storage
[0097] hard drive, U disk, input / output device, keyboard, printer, monitor, software, program, document, data,
