A weak order solution to a group ranking and consistency-driven pairwise comparisons

Ryszard Janicki, Waldemar W. Koczkodaj
1998 Applied Mathematics and Computation  
A novel non-numerical algorithm, based on a partial order, for solving a group ranking problem is compared with the more traditional consistency-driven approach.  ...  Both approaches are based on the fundamental concept ofpairwise comparisons. Potential applications are discussed.  ...  The method of consistency-driven pairwise comparisons allows us to express local preferences and compute the global merit index which can be used for drawing the final conclusions.  ...

Data Efficient Educational Assessment via Multi-Dimensional Pairwise Comparisons

Hyunbin Loh, Piljae Chae, Chanyou Hwang
2020 Educational Data Mining  
However, it is shown that using pairwise comparisons without the direct usage of instance features can show better assessments in the aspect of consistency, and speed.  ...  Whereas CJ requires direct comparisons of instances to obtain the final fit of the label, we give a generalization by proposing a label prediction model which uses the multi-dimensional features of pairwise  ...  In real-world systems, many assessment methods are based on domain expert knowledge, such as Knowledge Graphs, tagging of contents, and expert designed rule based models (such as the Rasch model in IRT  ...

Managing Null Entries in Pairwise Comparisons

W. W. Koczkodaj, Michael W. Herman, Marian Orlowski
1999 Knowledge and Information Systems  
This paper shows how to manage null entries in pairwise comparisons matrices.  ...  In practice, some experts may not be able (or available) to provide all assessments. Therefore managing null entries is a necessary extension of the pairwise comparisons method.  ...  The dynamic process of consistency analysis is facilitated by software, which locates and displays the most inconsistent assessments (as implemented in The Concluder system which has been released to the  ...
