Abstract

The invention relates to a device and a method for judging subjective questions in a test paper based on a natural language, the method including: processing a text of an answer of an examinee by clauses and dividing the text of the answer of the examinee into a plurality of clauses; carrying out word segmentation and part-of-speech tagging on the clauses after the clauses in the clause processingmodule; conducting keyword extraction of part-of-speech tagged words in part-of-speech tagging module; calling a syntactic analysis module to analyze the clause after the clause processing module, and analyzing the syntactic structure information of the clause; an obtaining module matching the keywords of the examinees' answers with the scoring keywords provided by the reference answers, and obtaining the similarity between the keywords of the examinees' answers and the scoring keywords; match the text clauses of the candidates' answers with the clauses provided by the reference answers, andobtaining the sentence similarity between the text clauses of the candidates' answers and the clauses provided by the reference answers. The invention realizes the machine correction of the subjectivequestion, lightens the burden of the marking teacher, improves the marking efficiency, and guarantees the fairness and justice of the scores of the examinees.
