Entity resolution is an important precess for many database based applications. Accurately identifying duplicate records between multiple data sources is a persistent problem that is big challenge to organizations and researchers. The aim of this process is to detect the approximately duplicate records that refer to the same real-world entity to make the database more concrete and achieve higher data quality.
