Abstract
A method for detecting incorrect categorization of data includes obtaining a database containing a plurality of entry-category pairs, calculating a score for each entry-category pair that corresponds to a likelihood that the pair contains an incorrect category assignment, and verifying the correctness of the assignment based on the score. The verification step can be conducted manually. The score assists users in focusing any manual verification efforts on data that may actually contain incorrect category assignments, thereby making the verification process more efficient. The method can be used to review and correct business name and phone number listings in telephone directories.
