Abstract
A method and apparatus for identifying and resolving conflicting data records are disclosed. The individual data fields of a master record are compared with the corresponding data fields of each source record in a particular data set. For each, one of various matching algorithms is used to assign a field matching score indicating the extent to which the data in the two data fields matches. The particular algorithm used to determine the extent of a match and to assign the corresponding score is dependent on the type of the data field. Once all of the data fields for a particular source record have been analyzed, the sum of the field matching scores is tallied to determine an overall record matching score for that particular source record.
