Coordinated Sharing Behavior Detection Conference

University of Sheffield, 29 October 2024

A one-day event bringing together some of the world's leading experts to showcase, discuss, and advance the state of the art in multimodal and cross-platform coordinated behavior detection

Event Rationale

The role of social media platforms during protests has been extensively documented, showing how these platforms facilitate coordination and amplify the voices of marginalized groups. However, the same tactics used by oppressed minorities can be repurposed by extremists, hate groups, trolls, and marketers. This recognition has led social media platforms, policymakers, and scholars to acknowledge the potential dangers. Consequently, platforms enforce actions against coordinated behaviors that violate community standards, with policies designed to be neutral regarding the content shared.

Since 2016, there has been a shift towards focusing on behavior rather than content to combat disinformation. This strategy avoids the limitations of content-based approaches and protects platforms from accusations of arbitrating truth. The concept of "coordinated inauthentic behavior," introduced by Nathaniel Gleicher of Facebook (now Meta), adds a layer of complexity by requiring authenticity. While some ambiguity is necessary to combat adversarial tactics aimed at evading detection, the lack of clear definitions and operationalization poses significant challenges for external researchers attempting to detect coordinated behavior on social media.

Scholars have developed open-source software toolkits to detect coordinated behavior, emphasizing the need to identify similar actions, such as sharing the same link or post in a closely timed and repetitive manner. The diverse forms of similarity, varying social media platforms, and evolving user behaviors make setting fixed detection thresholds difficult, often requiring case-by-case handling. The lack of universally recognized thresholds complicates the use of traditional machine learning approaches that rely on labeled datasets.

In this context, our upcoming conference, part of the vera.ai project's task "Tackling Coordinated Sharing Behavior with Network Science Methods," aims to explore the origins of coordinated behavior on social media, the challenges in developing detection tools, and the frontiers of cross-platform and multimodal detection. We will also address issues related to ethics and accountability and reflect on the role of coordination in light of the emergence of generative AI.
