An Extended Hilbert-Type Inequality with Two Internal Variables Involving One Partial Sums

open access: yesAxioms, 2023
By the use of the techniques of analysis and some useful formulas, we give a new extension of Hilbert-type inequality with two internal variables involving one partial sums, which is a refinement of a published inequality.

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

open access: yesProceedings 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 ...
