Since the last decade, the essay grading systems started using regression-based and natural language processing techniques. The vast majority of the essay scoring systems in the 1990s followed traditional approaches like pattern matching and a statistical-based approach. ( 2006) and Bayesian Essay Test Scoring System (BESTY) by Rudner and Liang ( 2002), these systems use natural language processing (NLP) techniques that focus on style and content to obtain the score of an essay. ( 2002) proposed E-rater and Intellimetric by Rudner et al. ( 1999) introduced an Intelligent Essay Assessor (IEA) by evaluating content using latent semantic analysis to produce an overall score. ( 2001) was released, which focuses on grammar checking with a correlation between human evaluators and the system. A modified version of the PEG by Shermis et al.
PEG evaluates the writing characteristics such as grammar, diction, construction, etc., to grade the essay.
The AES research started in 1966 with the Project Essay Grader (PEG) by Ajay et al. So, we need to evaluate all the answers concerning the question.Īutomated essay scoring (AES) is a computer-based assessment system that automatically scores or grades the student responses by considering appropriate features. Here the problem is for a single question, we will get more responses from students with a different explanation. The evaluation of essays is impossible with simple programming languages and simple techniques like pattern matching and language processing. It is a crucial application related to the education domain, which uses natural language processing (NLP) and Machine Learning techniques. The education system is changing its shift to online-mode, like conducting computer-based exams and automatic evaluation. Most automated evaluation is available for multiple-choice questions, but assessing short and essay answers remain a challenge. The assessment plays a significant role in measuring the learning ability of the student. In the present scenario, almost all the educational institutions ranging from schools to colleges adapt the online education system. We observed that the essay evaluation is not done based on the relevance of the content and coherence.ĭue to COVID 19 outbreak, an online educational system has become inevitable. We studied the Artificial Intelligence and Machine Learning techniques used to evaluate automatic essay scoring and analyzed the limitations of the current studies and research trends. This paper provides a systematic literature review on automated essay scoring systems. Few researchers focused on Content-based evaluation, while many of them addressed style-based assessment. Many researchers are working on automated essay grading and short answer scoring for the last few decades, but assessing an essay by considering all parameters like the relevance of the content to the prompt, development of ideas, Cohesion, and Coherence is a big challenge till now. Present Computer-based evaluation system works only for multiple-choice questions, but there is no proper evaluation system for grading essays and short answers. This connection online examination system evolved as an alternative tool for pen and paper-based methods.

The drawback of manual evaluation is that it is time-consuming, lacks reliability, and many more. As the number of teachers' student ratio is gradually increasing, the manual evaluation process becomes complicated. The present evaluation system is through human assessment. Assessment in the Education system plays a significant role in judging student performance.
