COSMOS Research Center is pleased to announce a new publication in Springer’s Journal of Social Network Analysis and Mining titled “Identifying Cohesive Narrative Formations in Cross-Platform Trade-War Discourse Using Weighted Contextual Focal Structures Analysis.”

Geopolitical discourse across social media platforms rarely unfolds in isolated silos. Instead, complex storylines emerge through the dynamic interplay of user interactions, semantic alignment, and cross-platform mechanics. Traditional Contextual Focal Structure Analysis (CFSA) models have helped identify context-specific user groups, but they treat all connections equally and analyze apps separately. This makes it difficult to capture subtle semantic nuances, stance homogeneity, or varying interaction intensities across platforms. The study addresses these issues by introducing Weighted Contextual Focal Structures Analysis (W-CFSA), a novel framework that evaluates multiple platforms at once. By combining custom platform weights, interaction frequency, and text similarity, W-CFSA analyzes the entire network layout to identify highly connected groups that share the same core message.

Using a dataset of 73,266 posts collected from YouTube, TikTok, X (formerly Twitter), and Instagram during the 2025 U.S.-China trade policy discussions, the researchers systematically benchmarked W-CFSA against size-matched eigenvector-centrality baseline groups. The findings demonstrated that W-CFSA substantially outperformed standard baseline methods across all structural metrics. The identified focal sets maintained consistently higher internal weighted density and clustering coefficients while exerting a far greater impact on global network transitivity when suspended. Qualitative analysis further revealed that these focal sets correspond to distinct narrative architectures like specific causal interpretations of policy volatility or strategic leverage, rather than simple stance or sentiment categories.

This research advances computational social science by offering trust, safety, and strategic communication teams a methodological framework to trace cross-platform narrative propagation at its core. By bridging network topology with semantic context, COSMOS continues to pave the way for a deeper understanding of digital discourse and information ecosystems.
