Abstract: [Objective] To analyze the research status and future research direction of Entity Resolution(ER) over relational databases. [Methods] Systematical researches are made on the accuracy and efficiency aspects of ER. The accuracy of ER is based on incremental methods, statistical methods and related information. The efficiency of ER is based on blocking, string similarity and other ideas. [Results] Maximizing precision and efficiency are the main goals of ER, but the research on dynamic evolution, heterogeneity of data sources and inexact string matching still faces significant challenges. [Limitations] Only precision and efficiency in the process of ER are discussed, but the characteristics and limitations of ER model don’t get the same level of attentions. [Conclusions] This paper gives a comprehensive overview of the process of ER over relational databases, research status and future research direction.
