ScoreStandalone and scoreIncremental Elements

The ScoreStandalone and scoreIncemental elements are used to calculate a Match Score for a profile that is designated as a potential match and can assist a data steward when reviewing potential matches.

Optional: Yes; If using this feature, use these parameters together as a pair.

If you have set the match group TYPE to suspect, then you may include these two elements in the match group’s configuration as shown below.

       "matchServiceClass": "com.reltio.businesslogic.match.providers.internal.InternalMatchService",
       "scoreStandalone": 80,
       "scoreIncremental": 10

Set each to a numeric value from 0 to 100. If the profile becomes a potential match, then the scoreStandalone and scoreIncremental values defined in the individual match groups will be used to form the Match Score for the profile as follows: Of the ‘suspect’ match groups that returned true, the Match Score is first set to the largest scoreStandalone of all the scoreStandalone scores. It is then increased by all the scoreIncremental scores with the exception of the scoreIncremental score that came from the same match group that provided scoreStandalone.

This calculation is performed if scoreStandalone and scoreIncremental are provided and does not need to be enabled by any other setting.

Note: The Match Score does not represent the score for a pair of profiles. When viewed in the Potential Matches view of the Hub (as shown below), it is not trying to convey the strength of one pair against another pair. Instead, it conveys the importance of a particular profile across all the match groups you have defined, in terms of the number of rules that evaluated to true for it, and if any particular one of those rules had a significantly high scoreStandalone. The premise is that you have chosen one or two of your rules to be far more important than the others and thus have given them a high scoreStandalone relative to the other rules. So, in the example shown, the profile on the right with a Match Score of 100 caused your most important rule (which presumably has a high scoreStandalone score) to evaluate to true as well as perhaps several others. Conversely, the profile to its left with a Match Score of only 50, did not enjoy that same amount of involvement so it is not considered as strong a profile in that regard.
