The slot value is a score. You may find that some fragments have several entries with different scores. The Bayes matcher finds all of the fragments in a string and sums up the scores for each GUID. The GUID with the highest sum is the match.
For example suppose you have the string “Joe’s Fish Market” and the following table represented part of your match results: Joe's 123 1 Joe's 7a3 2 Joe's 9b6 1 Fish 9b6 1 Meat 7a3 2 Barber 123 1 Emporium 7a3 2 Market 9b6 1 Shop 123 1 That would result in the following scores: 123 1 7a3 2 9b6 3 And the matcher would select account 9b6.
