    Short Answer Grading Using String Similarity And Corpus-Based Similarity
    (SCIENCE & INFORMATION SAI ORGANIZATION LTD, 2012-11) Fahmy, Aly A; Gomaa, Wael H
    Most automatic scoring systems use pattern based that requires a lot of hard and tedious work. These systems work in a supervised manner where predefined patterns and scoring rules are generated. This paper presents a different unsupervised approach which deals with students' answers holistically using text to text similarity. Different String-based and Corpus-based similarity measures were tested separately and then combined to achieve a maximum correlation value of 0.504. The achieved correlation is the best value achieved for unsupervised approach Bag of Words (BOW) when compared to previous work.
