The Link King: Record Linkage and Consolidation Software
From the website:
In the realm of public domain software for record linkage and unduplication (aka. dedupe software), The Link King reigns supreme. The Link King has fashioned a powerful alliance between sophisticated probabilistic record linkage and deterministic record linkage protocols incorporating features unavailable in many proprietary record linkage programs. (detailed overview (pdf))
The Link King’s probabilistic record linkage protocol was adapted from the algorithm developed by MEDSTAT for the Substance Abuse and Mental Health Services Administration’s (SAMHSA) Integrated Database Project. The deterministic record linkage protocols were developed at Washington State’s Division of Alcohol and Substance Abuse for use in a variety of evaluation and research projects.
The Link King’s graphical user interface (GUI) makes record linkage and unduplication easy for beginning and advanced users. The data linking neophyte will appreciate the easy-to-follow instructions. The Link King’s artificial intelligence will assist in the selection of the most appropriate linkage/unduplication protocol. The technical wizard will appreciate the discussion of data linkage/unduplication issues in The Link King’s user manual, the variety of user-specified options for blocking and linkage decisions, and the powerful interface for manual review of “uncertain” linkages.
Looks very interesting but requires an SAS “base license.”
I don’t have pricing information for an SAS “base license.”
