You can use alias files to remap and normalize RSS feed categories in the concentrator module.
Example:
Hacker HackerOne hackerNews hackMeUp News RT CNN CBS SpiesTalking BIS VZ UZSI GRU CIA NSA MI6 BND
Categories like hAckErnews, hackMeup, hackMeUp, hacker, HAcKER are all transformed to #Hacker. Categories like RT, rt, Cnn, CNN, etc are all transformed to #News. Finally, agencies labels (case insensitive) are rewritten to #SpiesTalking.
