Duplication: I would like to get similarity score (in Percentage), for similar data rows

Hey Folks, Could anybody able to help me with this?
Here is sample data row 1 and row 6, 7 are similar records, I would like to get extra column where I can see the similarity score for e.g. 80% (Similarity of data in row 1 and 6) How can this be achieved using Knime?
I heartly thankful for your attention!

Warm Regards,
Sac

How do you define “similarity” and what are you basing it on? Can you share some sample data?
