Subjective question self-adaptive examination paper marking method based on answer implication and dependency relationship

Abstract

The invention discloses a subjective question self-adaptive examination paper marking method based on answer implication and a dependency relationship. The subjective question self-adaptive examination paper marking method comprises the following steps of 1, analyzing a question; 2, analyzing a standard answer; 3, analyzing student answers; 4, judging whether head words are verbs of the student answers or not; 5, marking the head words which are not the verbs of the student answers; 6, marking the head words which are the verbs of the student answers. Firstly, through the dependency relationship, sentence components of an interrogative in a subjective question and the dependency relationship constituted by the sentence components and the head words are determined; then, according to the sentence components of the interrogative, core semantics of the standard answer and the student answers is determined; finally, through the adoption of a method based on the answer implication, the dependency relationship and the term similarity, omission of the student answers for all the components is subjected to self-adaption, self-adaptive examination paper marking of the same standard answer in different answering modes is achieved, and the accuracy and practicability of a subjective question examination paper marking system are further improved. Therefore, the subjective question self-adaptive examination paper marking method based on the answer implication and the dependency relationship has a wide application prospect in the field.
