Problems Identified (5)
KG ranking vulnerability to perturbations: Crowdsourced knowledge graphs are vulnerable to intentional or unintentional perturbations that can significantly affect rankings derived from the graphs.
Structural ranking stability assessment: The paper addresses the need to understand how relationship-level perturbations affect the stability of entity rankings in knowledge graphs.
Entity-level perturbation focus gap: Prior work has mainly focused on detecting and preventing entity-level perturbations rather than assessing structural ranking stability.
