Entity Resolution is the process of identifying and merging records that refer to the same real-world entity across different data sources. This is crucial in data management, as it helps eliminate duplicates and ensures that information is accurate and consistent. For example, two records for the same person might have slight variations in their names or addresses, and entity resolution helps to recognize them as one individual. The techniques used in entity resolution often involve algorithms that analyze similarities in data attributes, such as name, address, or phone number. By applying these methods, organizations can create a unified view of their data, which enhances decision-making and improves customer relationship management.
