Summary

Two indicators are usually adopted to measure quality of coding: coding rate (percentage of coded texts on the total of texts to be coded) and precision rate (percentage correct coded texts on the total of coded texts). The quality analysis is usually based on coding texts multiple times and reconciling different codes assigned to the same texts, usually based on a sample of the coded descriptions. The expected values of these rates are different depending on some factors like the complexity of the classification and the detail level of the codes to be assigned.
