Shift Error Detection in Standardized Exams
Hundreds of millions of multiple choice exams are given every year in the United States. These exams permit formfilling shift errors, where an absent-minded mismarking displaces a long run of correct answers. A shift error can substantially alter the exam’s score, and thus invalidate it. In this paper, we develop algorithms to accurately detect and correct shift errors, while guaranteeing few f...

متن کاملFraud Detection in Selection Exams Using Knowledge Engineering Tools
This paper proposes a method for fraud detection in automated selection exams, using knowledge engineering tools for identifying groups of answers with a strong indication of fraud, based on probabilistic evidence. Founded on an analysis of the wrong answers of the various candidates, the proposed method enables identification of suspicions, and evidence of fraud attempts through finding candid...
