Abstract

The increasing volume of data generated by heterogeneous information systems has created significant challenges in data integration, particularly when datasets contain different column names, data types, formats, and structural representations. Traditional data integration approaches rely heavily on manually defined mapping rules and predefined transformation procedures, making them difficult to maintain when integrating data from multiple sources. This paper proposes an Intelligent Multi-Source Data Integration Framework Using Machine Learning for Schema Matching and Data Transformation. The proposed framework aims to automate the identification of semantically equivalent attributes across multiple datasets by combining lexical, structural, statistical, and semantic features. A machine learning-based schema matching model estimates the similarity between source attributes and recommends corresponding target attributes using confidence scores. Based on the identified mappings, a transformation engine standardizes data formats, resolves selected inconsistencies, and combines compatible records into a unified dataset. The framework also incorporates data profiling, data quality assessment, transformation validation, and reporting mechanisms to improve integration reliability. The proposed system is designed to support structured data sources, including CSV files, Excel spreadsheets, and JSON datasets, with the potential for extension to relational databases. Its effectiveness can be evaluated using schema matching precision, recall, F1-score, transformation accuracy, execution time, and data quality improvement. The framework aims to reduce manual mapping effort, improve integration consistency, and provide a flexible foundation for intelligent data integration in data engineering applications.

Full Article/Conclusion

This paper presents the design of an Intelligent Multi-Source Data Integration Framework Using Machine Learning for Schema Matching and Data Transformation. The proposed framework addresses the challenges of integrating heterogeneous structured datasets with inconsistent attribute names, data types, formats, and representations. By combining schema profiling, lexical and statistical analysis, structural information, and optional semantic features, the framework aims to identify corresponding attributes more intelligently than approaches based exclusively on predefined rules. The integration pipeline connects matching predictions with controlled data transformation, quality validation, and reporting.The use of confidence-based decisions and human review provides a mechanism for handling ambiguous mappings, while transformation logs support traceability and reproducibility. The proposed implementation can be developed using Python, Pandas, scikit-learn, Streamlit, and SQLite. Future work may explore transformer-based semantic matching, active learning from user corrections, incremental integration for evolving schemas, and large-scale processing of additional data formats. A systematic comparison with established matching techniques is necessary to quantify the framework's benefits, limitations, and generalization capability.
