How is Suggester Merge Confidence Score Calculated?

I have 8 golden records suggested for merge with a Suggester Merge Confidence Score = 45. If I look at each individual matches the score averages to >97, which should have caused an automatic merge. 


Curious to know How is Suggester Merge Confidence Score Calculated?




Hello Hitesh,


The B_SUGGMERGECONFSCORE is the confidence score for the suggested match group.

If you check all the records for this suggestion group, do you have more results that would tend to this score of 45.

You can check this with the column  B_SUGGMERGEID.

Hello Hitesh,


To understand what is happening here, we will need to exchange further explanations and screenshots.

So I will open a ticket based on this forum and we can take it over there.


If there is anything interesting to share to the community, I will update this forum afterwards.


Thank you and talk to you over there.

Hello !

Same question here, I'm debugging a matcher and here is my situation : 

- in DU table, I get a B_MATCHSCORE of 85 on 5 records => same name, first name and email, so I get the expected B_MATCHSCORE

- but then in MI table, the B_SUGGMERGECONFSCORE decreases to 61


When I debug into the the management > integration batches, I can find all SQL queries updating DU and MI tables, EXCEPT the one which (I think) calculates the B_SUGGMERGECONFSCORE, in the step "Refine Non Singleton Groups" :

Could you please provide the SQL executed in this part of the integration process so I can finally find how the B_SUGGMERGECONFSCORE is calculated ?


Thanks !

Hello Alexis,

The B_MACTHSCORE is defined for all effective couples of masters identified in DU.

However the suggested merge conf score is based on all couples of suggestions.

So you'll need first to identify all the masters present in your suggested merge group (B_SUGGMERGEID) and then query the DU table to bring back all those couples of masters to determine the end suggested merge conf score.
