Development of An Evaluation Paradigm for “ RecordMatch ” and its Application to GenMergeDB Clustering Results

For years, the LDS Church has allowed genealogical patrons to search for their ancestors amongst large collections of indexed records where each record has been treated as independent of all other records. Recently, the Church has begun to consider the potential for providing patrons with clustered results of records. These clusters would attempt to identify the same entity across multiple record collections. This clustering process, which we will refer to as “RecordMatch” is, in essence, a very large entity disambiguation task across partially-populated records. We describe and implement a rigorous evaluation for RecordMatch by taking advantage of the groundwork lain by comparable evaluations in the research community. We then apply this evaluation framework to the results of an existing genealogical record-merging system, GenMergeDB, and demonstrate the high-level of success of existing technologies for the purpose of producing RecordMatch-type clusters.
