Finding Matching Entities
How do I find matching entities using Smart Matching?
side bar
When you pasted the contents of Example 8 merge 3.anb into your initial
chart, the accounts did not merge automatically. This is because the account
numbers are in a different format, for example 0942-5473 and 09425473. However,
these two accounts the same "real world" account, as the digits are identical, just
in slightly different formats.
Smart Matching uses a set of predefined rules for deciding whether one entity
could be the same real-world object as another. It does this by examining entities
and their links, and comparing their entity types and their property values to
produce an overall score of between 1 and 10. The score is an indication of the
probability of the two entities being the same real-world object.
The score ranges from one, which indicates the weakest match, to 10, which
indicates a perfect match. The threshold can be used to produce fewer but
stronger matches, or more but weaker matches.
Find all of the accounts that contain the same account number and merge them.
To do this:
1. From the Analysis menu, select Find Matching Entities to display the Find
Matching Entities dialog.
The Find Matching Entities dialog is typically docked to the main application
