Inter-Rater Reliability in Language Testing

That paper entitled Assessing inter-rater agreement for nominal judgement variables, (alternative link) summarizes a simple comparative study between Cohen's Kappa and Gwet's AC₁ for evaluating inter-rater reliability in the context of Language Testing, dichotomous variables, and high-prevalence data.  Researchers may find this analysis instructive. I personally found it attractive for its simplicity, and the clarity of the examples used. Those who are new in the area of inter-rater reliability assessment may find it useful as well.
