Abstract

Diagrammatic languages are widely used in computer science education for modeling software systems, databases, and algorithms. However, automatically grading diagrams in competitive or educational assessment platforms remains challenging. This paper presents an integrated extension for Mooshak 2.0 that automates the evaluation of visual diagrams. The system pairs the Eshu web editor with a graph matching engine that evaluates student submissions against reference solution models, calculates structural and semantic similarity scores, and returns detailed feedback to learners.
