Does Markaaz do fuzzy logic to determine its match grades?

Yes, Markaaz leverages fuzzy logic to help in modeling complex systems where traditional binary logic might fall short. 

For instance, Markaaz assigns an A grade if all the tokens or components of an address match perfectly. If one token fails, we assign a B. If there is a similarity but not a perfect match with some tokens, we assign a C. If nothing matches, we assign an F.
