generating an edge weighting value for each source target object pair having a match score higher than the match threshold value based on the match score applied to the source target object pair;

determining a set of candidate cuts based on the edge weighting values, each candidate cut relating to one or more edges linking elements of the disjoint set data structure; scoring each candidate cut based on an expected error rate of the binary classifier; and

performing one of the candidate cuts based on a score assigned by the binary classifier being above a cut threshold value;

creating a plurality of sub-clusters, each sub-cluster comprising a subset of elements of the disjoint set data structure;

recursively repeating the determining, scoring, and performing steps for each sub-cluster of the plurality of sub-clusters; and

defining a new entity object for each sub-cluster based on a score assigned by the binary classifier being below the cut threshold value.

ranking the source target object pairs having a match score higher than the match threshold value based on match scores;

selecting a subset of the ranked source target object pairs based on a likelihood that the source object and the target object of each source target object pair of the subset are associated with the same object; and

creating a persistent entry for each source target object pair of the subset, each persistent entry indicating the likelihood that the source object and the target object are associated with the same object.

a target object identifier; and

at least one related value.

10. The computer-implemented method of claim 9 wherein performing the cleaning operation further comprises one or more of normalizing the case of text, normalizing punctuation of text, and expanding abbreviations of text.

11. The computer-implemented method of claim 9 wherein the cleaning operation is performed prior to generating the index.

12. The computer-implemented method of claim 7 further comprising generating a separate index for each value of the partition key.

13. The computer-implemented method of claim 1 wherein each source object in the group of source objects comprises a source object identifier.

14. The computer-implemented method of claim 13 wherein each source object in the group of source objects further comprises a source object partition key.

16. The computer-implemented method of claim 1 further comprising performing a cleaning operation on one or more data values of each source object of a group of source objects.
