The IdentityMatch function tries to match source data with reference data, using specified attributes to calculate the similarity score of each source-reference pair, and then computes the final similarity score.
Typically, the source data is about business customers and the reference data is from external sources, such as online forums and social networking services. The IdentityMatch function is designed to help determine if customers with similar identifiers are the same customer. The function supports both nominal (exact) matching and weighted fuzzy matching.
