Computing krippendorff's alpha-reliability
WebIn this study we do not focus on the retrieval performance of our system but on the relevance assessments and the inter-assessor reliability. To quantify the agreement we apply Fleiss’ Kappa and Krippendorff’s Alpha. When we compare these two statistical measures on average Kappa values were 0.37 and Alpha values 0.15. Webkrippalpha computes Krippendorff's reliability coefficient alpha.

WebIt applies the Krippendorff's Alpha methodology for nominal, ordinal, interval, or ratio levels of measurement, and, if desired, produces confidence intervals. Parallel computing is supported, when applicable. If the level of measurement is nominal, the discrete metric ( nominal.dist) is employed by default. WebKrippendorff's alpha coefficient, named after academic Klaus Krippendorff, is a statistical measure of the agreement achieved when coding a set of units of analysis.Since the 1970s, alpha has been used in content analysis where textual units are categorized by trained readers, in counseling and survey research where experts code open-ended interview …
WebKrippendorff’s Alpha is a measurement of inter-rater reliability.
