In an illustrative embodiment, an apparatus, computer-readable medium, or method may be configured to suggest correct identifiers. Expected identifiers may be created and their frequencies of occurrence may be calculated. Unrecognized identifiers may be detected. First numerical scores indicating that the unrecognized identifiers were provided in place of one or more expected identifiers may be calculated. Second numerical scores indicating that the unrecognized identifiers were intended to include expected identifiers may also be calculated. The second numerical scores may be calculated using the first numerical scores and the frequencies of occurrence of the expected identifiers. The system may select one or more expected identifiers based on the second set of numerical scores.
