Applying Natural Language Processing (NLP) For Automated Code Review

Automated code review aims to reduce manual effort, catch defects early, and improve code quality by using machine learning and Natural Language Processing (NLP) to analyze source changes, generate review comments, and prioritize reviewer attention. This paper surveys prior work and presents a practical methodology combining transformer-based code models (e.g., CodeBERT/CodeT5-style encoders), structural program representations (ASTs/graphs), and comment-generation components to build an automated code review assistant. We describe dataset collection from open-source pull requests, preprocessing, model design, evaluation metrics, and an implementation plan. Finally, we discuss expected benefits, limitations, and directions for future work. (arXiv)
