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 for: creating expected identifiers in a computing environment; calculating frequencies of occurrence of the expected identifiers in the computing environment; detecting one or more unrecognized identifiers received by the computing environment; calculating first numerical scores using a string matching algorithm and a keystroke penalty matrix, where the first numerical scores indicate that one or more unrecognized identifiers were provided to the computing environment in place of one or more expected identifiers; calculating second numerical scores using the first numerical scores, the frequencies of occurrence of the one or more expected identifiers, and Bayes theorem, where the second numerical scores indicate that one or more unrecognized identifiers were intended to include one or more expected identifiers; and selecting one or more expected identifiers based on the second numerical scores.
