17. The computer program product of claim 16 , wherein the executable code is configured to cause the one or more processors to: determine a respective plurality of item tokens associated with each respective one of the plurality of item character strings, wherein a correlation value associated with each one of the tokens is determined, based on determining a correlation of the each one of the tokens with the brand character string associated with the brand partition set that includes the item associated with the item character string that includes the each one of the tokens.
