AI-Enabled Data Profiling Techniques for Quality Improvement

Abstract

AI is transforming data profiling by making data quality assessment more automated, scalable, and intelligent. Traditional methods struggle with modern, complex, and diverse datasets, while AI techniques—such as machine learning, deep learning, and statistical models—can detect anomalies, recognize patterns, and predict data quality issues across both structured and unstructured data. The study reviews the evolution from rule-based profiling to adaptive AI-driven approaches, highlighting methods like clustering, classification, and natural language processing. It also proposes a framework integrating AI into key stages of data profiling, including data ingestion, preprocessing, feature extraction, anomaly detection, and quality scoring, with continuous learning and dynamic rule generation. Results show that AI-based profiling significantly improves data completeness, consistency, and timeliness compared to traditional methods. Despite challenges in implementation, AI-powered data profiling represents a major advancement in data quality management, with future directions focusing on explainable AI, real-time processing, and big data integration.
