OpenMRS: Record Linkage Project

Now that Phase3 is ready for review, we have added weight scaling functionality to patient matching module. In fact, I have both versions of weight scaling implemented (Framework A and B). This week, I will be performing performance tests this week to determine if there is noteworthy performance difference between these two approaches.

3. Runtime Component, operational:  Modify the ScorePair method to incorporate frequency scaling.  This process should be performed incrementally, in two phases.The first phase will hard code the frequency scaling equation, into the existing ScorePair method.  Once the entire linkage process (from analytics to operational phase) has been tested and successfully implements frequency scaling as a prototype, we will proceed to phase 2.In the second phase ScorePair will be re-factored to accommodate a framework that accepts future modifications to linkage scores established by the Felligi-Sunter model.  These modifications include the frequency scaling, and will also include modifying the agreement weight based on the degree of string similarity as established by various string comparators.
