About Solution
Advanced AI application designed to accurately and impartially grade student’s answer sheets. Our state-of-the-art technology ensures precise evaluation, providing assessments without any bias.
The application revolutionizes the grading process for educational institutions, offering a time-saving and reliable solution. Teachers can effortlessly scan and upload students’ answer sheets, allowing the AI-powered system to accurately evaluate and assign marks. This streamlines the grading workflow, freeing up valuable time for educators to focus on providing personalized feedback and facilitating student growth. With its unbiased assessment and consistent standards, It ensures fair and objective grading, contributing to a more efficient and effective educational environment.
The Approach for the solution
The solution employs an AI framework to ensure an automated precise and unbiased grading of students’ answer sheets. Leveraging advanced technologies, including Object Detection Models and Optical Character Recognition (OCR) model TrOCR, our system operates seamlessly. Educators upload ideal answers as a reference and source of truth for grading student’s answers. The uploaded answer sheets undergo a comprehensive process: first, the YOLOv8 model precisely pinpoints the answered questions’ locations, using coordinates to identify them accurately.Then, the system employs the Projection Profile Method Algorithm to correct the skew angle of the answer sheet, enhancing the accuracy of subsequent analysis.
Post-angle correction, every answer undergoes a thorough analysis through the TrOCR model. This process involves extracting text and conducting meticulous checks for spelling errors, ensuring the utmost precision in word recognition. This intricate, multi-layered approach serves to refine and meticulously prepare student responses for subsequent evaluation.
To evaluate student answers, the system utilizes a cutting-edge BERT model (NLP). This model compares the extracted answers against the uploaded correct solutions, providing a scoring mechanism based on their semantic similarity. The aggregated scores then determine the final marks displayed on the dashboard.
Additionally, before settling on TrOCR, we experimented with multiple OCR engines such as EasyOCR, TesseractOCR, and PaddleOCR. TrOCR demonstrated the highest accuracy in extracting text from the answer sheets, contributing to the system’s overall effectiveness.
The integration of these technologies, such as Object Detection, the Projection Profile Method Algorithm, OCR (specifically TrOCR), and BERT, facilitates an automated and accurate assessment process. This empowers educators with reliable grading while maintaining fairness and objectivity in evaluations.
