Project Overview

The Student Assessment System is an advanced grading solution designed to automate evaluation processes, detect plagiarism, and identify malpractice in academic submissions. It leverages machine learning, AI-based content analysis, and OCR for handwritten assignments to ensure academic integrity and streamline grading workflows.

Key Features

• Answer Verification: Automates answer evaluation by comparing submissions with a predefined answer key, detecting plagiarism and malpractice.
• Assignment Verification: Checks assignment originality, structure, and formatting while detecting peer-to-peer copying.
• Plagiarism Detection: Uses APIs and algorithms for detecting online and peer plagiarism.
• AI Content Detection: Identifies AI-generated content in assignments to ensure originality.
• OCR Integration: Converts handwritten submissions into digital text for verification (currently under optimization).
