Entity Resolution and Analysis (ER&A)

This is the capability to resolve multiple labels for individuals, products or other noun classes of data into a single resolved entity, and analyze relationships among such resolved entities. Multiple references may result from data entry errors, inconsistency due to multiple systems for entering data, intentional falsification of information, or the creation of false identities. Entity resolution and analysis (ER&A) leverages many aspects of data integration, master data management (MDM) and data quality management, and eventually becomes instrumental in the success of each of these practices. Additionally, all four of these disciplines (that is, data integration, MDM, data quality management and ER&A) make up a significant portion of the implementation which takes place under enterprise information management.
