Automatic Wrong Option Generation Based on Confusion Degree

摘要

While a person designs a choice question with multiple options, he or she requires some incorrect options as well as correct option. And incorrect options need to be looked like correct so that the correct option cannot be easily selected out. Question answering(QA) can hardly provide incorrect options because it only focuses on searching correct answer. This paper gives a method to generate incorrect options for a certain question and a given correct option. Confusion degree is proposed to describe the degree of an incorrect option being mistakenly considered as correct. Experiment shows that the method can effectively generate incorrect and confusing options for a question. The method can help design choice questions in an examination.
