Environment
TIBCO EBX 6.0.5
Add-on Name: Match and Merge: 5.3.0
Resolution
Weight In the Matching Policy:
We have two kinds of weight in the matching policy:
1) One is used for the decision tree when you select the average function.
Example: There are 2 matching fields: First Name (weight 2) and Last Name (weight 1). So the average score for this node = (2 x First name score + 1 x Last name score)/3
2) The other is in the Matching field settings, used for the pre-processing. The fields which are more "important" for the comparison (e.g., when those "important fields" match, the decision can go straight to Match regardless of the other fields) should be assigned to a higher weight.
Example: There are 4 matching fields: First Name, Last Name, Social number, DOB. If in your decision tree, the people who have the same Social number can be matched regardless of the other fields, you should assign the Social number a much higher weight than the other fields in Matching field settings. Otherwise, those 2 records that have only the same Social number won't make it pass the pre-processing and will be returned as No match.
