20.500.12556/RUL-168065 Hybrid rumor debunking in online social networks a differential game approach Online social networks (OSNs) facilitate the rapid and extensive spreading of rumors. While most existing methods for debunking rumors consider a solitary debunker, they overlook that rumor-mongering and debunking are interdependent and confrontational behaviors. In reality, a debunker must consider the impact of rumor-mongering behavior when making decisions. Moreover, a single rumor-debunking strategy is ineffective in addressing the complexity of the rumor environment in networks. Therefore, this article proposes a hybrid rumor-debunking approach that combines truth dissemination and regulatory measures based on the differential game theory under adversarial behaviors of rumor-mongering and debunking. Toward this end, we first establish a rumor propagation model using node-based modeling techniques that can be applied to any network structure. Next, we mathematically describe and analyze the processes of rumor-mongering and debunking. Finally, we validate the theoretical results of the proposed method through various comparative experiments, including comparisons with a random strategy, a uniform strategy, and single strategy models on real-world datasets collected from Facebook, Twitter, and YouTube. Furthermore, we harness two actual rumor events to estimate parameters and predict rumor propagation, thereby affirming the veracity and effectiveness of our rumor propagation model. systems theory modelling social networks rumor spreading teorija sistemov modeliranje socialna omrežja širjenje govoric true false true Angleški jezik Slovenski jezik Članek v reviji 2025-03-27 12:40:39 2025-03-27 12:40:43 2025-06-18 14:38:05 0000-00-00 00:00:00 2025 0 0 Str. 2513-2527 no. 4 Vol. 55 Apr. 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 004.7:316.472.4-027.44 2168-2232 10.1109/TSMC.2025.3526734 229616643 Hybrid_Rumor_Debunking_in_Online_Social_Networks_A_Differential_Game_Approach.pdf Hybrid_Rumor_Debunking_in_Online_Social_Networks_A_Differential_Game_Approach.pdf 1 FF1608D71EE3B9269277C2F883A01069 bea77cdd0c213c8f3df27aa34b492051dea65e5814024c34be6e217acebcf867 82eb1490-0aff-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201060 https://ieeexplore.ieee.org/document/10849987 1 488bfadc-0aff-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201059 Fakulteta za elektrotehniko 0 0 0
