Abstract: [042] The present invention discloses a system for English grammar error diagnosis using rule-based and contextual language processing modules. The system integrates deterministic grammatical rule evaluation with contextual semantic language analysis to accurately identify, classify, explain, and recommend corrections for grammatical errors. An input processing module performs linguistic preprocessing, following which a rule-based grammar engine evaluates predefined grammatical rules while a contextual language processing module assesses semantic coherence and contextual correctness. A diagnostic fusion engine combines outputs from both modules using confidence-based validation to improve diagnostic accuracy and reduce false detections. An explanation generation module provides educational feedback together with contextually appropriate correction recommendations, while an adaptive learning module refines diagnostic confidence using user interaction history. The disclosed invention improves grammatical diagnosis precision, contextual consistency, explainability, and applicability across educational, professional, legal, technical, and enterprise language processing environments.
