1. A computer-implemented method of determining related records, the method comprising: retrieving a plurality of candidate health records, each candidate health record having one or more encounters, each of the one or more encounters associated with a date-time coordinate; for each candidate health record, sorting the one or more encounters in chronological order based on the date-time coordinates; determining a time difference between each serial encounter of the sorted one or more encounters, and assembling the time difference between each serial encounter as a time series; ranking the plurality of candidate health records; determining a candidate match for a first candidate health record and a second candidate health record of the plurality of candidate health records based on a threshold value applied to the ranked plurality of candidate health records; and merging a first candidate health record and a second candidate health record based on the candidate match.
