1. One or more tangible non-transitory computer-readable storage media for storing computer-executable instructions executable by processing logic, the media storing one or more instructions to: determine frequencies of occurrence of expected identifiers in a computing environment, wherein the frequencies of occurrence are determined based on usage data for the expected identifiers; detect one or more unrecognized identifiers in the computing environment; associate a first penalty score to first characters on a keyboard using a keystroke penalty matrix, the first characters being within a first distance of an entered character on the keyboard; associate a second penalty score to second characters on the keyboard using the keystroke penalty matrix, the second characters being within a second distance of the entered character on the keyboard, wherein the first penalty score exceeds the second penalty score and the first distance exceeds the second distance; calculate one or more first numerical scores using the keystroke penalty matrix, the first penalty score, and the second penalty score, wherein the one or more first numerical scores indicate that the one or more unrecognized identifiers were provided to the computing environment in place of one or more of the expected identifiers; determine second numerical scores using the first numerical scores and the frequencies of occurrence of the one or more expected identifiers, wherein the second numerical scores indicate that one or more unrecognized identifiers were intended to include one or more expected identifiers; and select one or more expected identifiers based on the second numerical scores.
