Embodiments determine mismatches in evaluations. Embodiments receive a first evaluation of an employee from a supervisor of the employee, the first evaluation including supervisor comment ratings and supervisor numerical ratings, each of the supervisor comment ratings and supervisor numerical ratings corresponding to an evaluation category. Embodiments receive a second evaluation of the employee from the employee, the second evaluation including employee comment ratings and employee numerical ratings, each of the employee comment ratings and employee numerical ratings corresponding to the evaluation category. Embodiments determine first sentiment polarity scores of the supervisor comment ratings and second sentiment polarity scores of the employee comment ratings. Embodiments determine polarity mismatch scores based on the first sentiment polarity scores and the second sentiment polarity scores and determine average differential ratings based on the supervisor numerical ratings and the employee numerical ratings. Embodiments combine the polarity mismatch scores and the average differential ratings.
