Merging is a research area that focuses on the integration of different datasets or sources of information to create a unified, comprehensive dataset. This process involves combining, aligning, and reconciling individual datasets to eliminate redundancies, inconsistencies, and errors. Merging is commonly used in fields such as data science, bioinformatics, and social sciences to enable more accurate analysis and decision-making. Researchers in this area develop algorithms, methods, and tools for merging diverse datasets while maintaining data integrity and quality.
