5. The system of claim 4 , further comprising: a token determination engine configured to determine a respective plurality of item tokens associated with each respective one of the plurality of item character strings, wherein the correlated segment engine is configured to determine a correlation value associated with each one of the tokens, 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.
