Weighting Schemes and Incomplete Data: A Generalized Bayesian Framework for Chance-Corrected Interrater Agreement [PDF]

, 2021
Van Oest (2019) developed a framework to assess interrater agreement for nominal categories and complete data. We generalize this framework to all four situations of nominal or ordinal categories and complete or incomplete data. The mathematical solution

A Head-Weighted Gap-Sensitive Correlation Coefficient [PDF]

Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval, 2015
Information retrieval systems rank documents, and shared-task evaluations yield results that can be used to rank information retrieval systems. Comparing rankings in ways that can yield useful insights is thus an important capability. When making such comparisons, it is often useful to give greater weight to comparisons near the head of a ranked list ...
