It maps the linguistic features to the human scores so that the computer can be used to classify (i.e. After that same essays are rated using machine learning algorithms. MethodologyĪn AES solution leverages a computer program that builds a scoring model by extracting linguistic features from a constructed-response prompt that has been pre-scored by human raters. These applications are developed to address the increasing demand for open-ended or constructed-response test questions, which prompt responses such as extended writing responses (e.g., essays, long format answer), shorter written responses to subject-matter items, and spontaneous speech, etc. NLP applies principles of linguistics and computer science to create computer applications that interact with human language. NLP technology is the foundation for the Automated Scoring Applications, also known as Automated Essay Scoring Applications. Outcomes of AES solutions are unbiased, error-free, and repeatable, even when irrelevant external factors are changed. Keeping the above challenges in mind, and for the sake of rationality, fairness, and reliability many institutions have switched to Automated Essay Scoring Solutions.

High cost – Manual essay scoring is a cost-intensive process as it involves a high cost of professional and qualified evaluators and other administrative costs.The entire process of evaluation, when carried out manually leads to many administrative and logistic issues also like transporting the exam papers, masking names, data entry, storing and record-keeping. Administrative and logistic issues – Manual process requires physical handling of essays and answer sheets, there by making it a very tedious process.Inconsistent outcome and prone to errors – Human or manual evaluation is bound to be inconsistent in terms of the outcome and also has a high probability of error.This makes the entire evaluation and scoring cycle slow and long. Applicants have to wait for a considerable amount of time to see the outcome. Time-consuming and slow – Manually scoring each essay is obviously a very time-consuming process.Large requirement for experienced and trained staff – Manual essay scoring has a huge dependency on the quality and experience of evaluators.Different evaluators might score the same essay differently because of the subjective impressions of the quality and concentration & fatigue level. is relatively straightforward for teachers to score because errors can be easily tracked and counted, but grading content, organization, coherence & relevance, sophistication are more difficult to score impartially in a manual process.

AES is one such measure for betterment of educational standards at a reduced cost and high speed with no compromise on quality Increasing education costs and expectations for high standards in evaluation process have led to pressure to hold the educational system accountable for results by imposing high evaluation standards. Some of them are cost, accountability, quality, accuracy & consistency and use of advanced technology. There are numerous factors responsible for increasing popularity of AES. The basic idea behind this approach to classify a large set of textual entities into a small number of discrete categories, corresponding to the possible grades. It involves use of specialized computer programs, typically Natural Language Programing (NLP) to assign grades to essays written mostly in an educational setting or otherwise for various other evaluation processes. Automated Essay Evaluations, popularly known as Automated Essay scoring (AES) is a form of educational assessment.
