Clerical review of Entity Resolution(ER) is crucial for maintaining the entity identity integrity of an Entity Identity Information Management (EIIM) system. However, the clerical review process presents several problems. These problems include Entity Identity Structures (EIS) that are difficult to read and interpret, excessive time and effort to review large Identity Knowledgebase (IKB), and the duplication of effort in repeatedly reviewing the same EIS in same EIIM review cycle or across multiple review cycles. Although the original EIIM model envisioned and demonstrated the value of correction assertions, these are applied to correct errors after they have been found. The original EIIM design did not focus on the features needed to support the process of clerical review needed to find these errors.
The research presented here extends and enhances the original EIIM model in two very significant ways. The first is a design for a pair of confirmation assertions that complement the original set of correction assertions. The confirmation assertions confirm correct linking decisions so that they can be excluded from further clerical review. The second is a design and demonstration of a comprehensive visualization system that supports clerical review, and both correction and confirmation assertion configurations in EIIM. This dissertation also describes how the confirmation assertions and the new visualization system have been successfully integrated into the OYSTER open source EIIM framework.
