Yuliia Baranetska . Intelligent Requirements Validation: An Empirical Evaluation of NLP Techniques for Automated Quality Assurance. International Journal of Computer Applications. 187, 53 ( Nov 2025), 58-66. DOI=10.5120/ijca2025925909
To ensure high-quality software at scale, faster and more reliable requirements validation is needed beyond manual methods. This paper examines the use of Natural Language Processing (NLP) for automated validation through a mixed-method study in the automotive and healthcare sectors. Manual validation was compared with an NLP-based approach on 50 requirements, assessing time, defect detection, and cost. The NLP method reduced validation time by 66.7%, identified 29.4% more defects, and lowered costs by 40%, with all differences being statistically significant. This paper discusses the workflow, dataset, annotation scheme (ambiguity, inconsistency, redundancy), implementation tools (spaCy, BERT, NLTK), and challenges (domain terminology, integration).
