Kappa-like agreement indexes are often used to assess the agreement among examiners on a categorical scale. They have the particularity of correcting the level of agreement for the effect of chance. In the present paper, we first define two agreement indexes belonging to this family in a hierarchical context. In particular, we consider the cases of a random and fixed set of examiners. Then, we ...
It has recently been shown that executions of authenticated Byzantine Agreement protocols in which more than a third of the parties are corrupted, cannot be composed concurrently, in parallel, or even sequentially (where the latter is true for deterministic protocols). This result puts into question any usage of authenticated Byzantine agreement in a setting where many executions take place. In...
Most of the existing feasibility results on Byzantine Agreement (BA) are of an all-or-nothing fashion: in Broadcast they address the question whether or not there exists a protocol which allows any player to broadcast his input. Similarly, in Consensus the question is whether or not consensus can be reached which respects pre-agreement on the inputs of all correct players. In this work, we intr...
Determine which Membership Category and Dues [1] level is appropriate for your organization. Review OASIS Policies and Procedures [2] to learn about OASIS governance and expectations. Identify a Primary Representative [3] who will be responsible for your organization's overall participation and a Billing Contact. Optionally, you may also identify an Official Notice Contact (usually your legal c...
We present an unsupervised approach to symmetric word alignment in which two simple asymmetric models are trained jointly to maximize a combination of data likelihood and agreement between the models. Compared to the standard practice of intersecting predictions of independently-trained models, joint training provides a 32% reduction in AER. Moreover, a simple and efficient pair of HMM aligners...
We propose a new segmentation evaluation metric, called segmentation similarity (S), that quantifies the similarity between two segmentations as the proportion of boundaries that are not transformed when comparing them using edit distance, essentially using edit distance as a penalty function and scaling penalties by segmentation size. We propose several adapted inter-annotator agreement coeffi...
This article presents an alternative explanation for the Anaphor-Agreement effect, the generalisation that anaphors do not occur in syntactic position construed with agreement (cf. Rizzi 1990). I propose that this effect finds its explanation in the theory of argument marking. Arguments must be marked by either case or agreement for reasons of LF visibility (cf. Chomsky 1986). However, when an ...
Statistical measures are described that are used in diagnostic imaging for expressing observer agreement in regard to categorical data. The measures are used to characterize the reliability of imaging methods and the reproducibility of disease classifications and, occasionally with great care, as the surrogate for accuracy. The review concentrates on the chance-corrected indices, kappa and weig...
