“…The most straightforward example of this analysis is the string-based similarity between words which can be identified through similarity measures such as Cosine and Jaccard. In addition, sometimes the morphology of words could be extended to consider the ASCII code representation of characters within the essay answer ( [38]; [39]; [40]). The way of adopting this feature analysis into an unsupervised technique is simply represented through the use of clustering where similarity values between answers (produced by Cosine or Jaccard) are being used to aggregate similar answers in a single cluster [18].…”

“…The utilization of these approaches for supervised AES is simply represented by feeding a regression technique with answer document vectors [38]. Otherwise, a distance measure such as Cosine can be used to determine similarity between answers documents through an unsupervised technique ([2]; [6]; [18]; [40]).…”
