Entity Resolution and Information Quality

3. Entity Resolution Models

Overview

This chapter presents three models of ER. The models are complementary in that they address different levels and aspects of the ER process. The first and earliest model discussed is the Fellegi-Sunter Model, a methodology for linking equivalent references by direct matching. The Fellegi-Sunter Model provides a specific algorithm for of resolving pairs of references through probabilistic matching. The second model is the Stanford Entity Resolution Framework (SERF), which defines a generic model of ER in terms of matching and merging operations that act on pairs of references. Unlike Fellegi-Sunter, the SERF model does not define a specific implementation for the match (or merge) operation but instead focuses ...
