Analyzing increasingly complex graphs presents significant challenges, particularly when integrating diverse data types like textual content and network structures, where the whole often becomes greater than the sum of its parts. Using the Enron email dataset, we first create a foundational graph layer with email addresses as nodes and email exchanges as edges. The second graph layer represents these interactions as nodes, structured as textual triplets, with edges representing communication chains. These triplet text nodes are then transformed into vectors using a transformer model, followed by the application of a Graph Neural Network (GNN) Link Prediction model. The resulting output vectors, which integrate both semantic content and graph structure, are used to construct a third graph layer based on pairs with high cosine similarities. This third graph layer aids in identifying influencers and enhances the understanding of engagement dynamics within the network. This multi-layer approach provides a comprehensive framework for analyzing complex textual interactions within graph structures, offering deeper insights into network dynamics, and demonstrating that the whole is indeed greater than the sum of its parts.

摘要

Analyzing increasingly complex graphs presents significant challenges, particularly when integrating diverse data types like textual content and network structures, where the whole often becomes greater than the sum of its parts. Using the Enron email dataset, we first create a foundational graph layer with email addresses as nodes and email exchanges as edges. The second graph layer represents these interactions as nodes, structured as textual triplets, with edges representing communication chains. These triplet text nodes are then transformed into vectors using a transformer model, followed by the application of a Graph Neural Network (GNN) Link Prediction model. The resulting output vectors, which integrate both semantic content and graph structure, are used to construct a third graph layer based on pairs with high cosine similarities. This third graph layer aids in identifying influencers and enhances the understanding of engagement dynamics within the network. This multi-layer approach provides a comprehensive framework for analyzing complex textual interactions within graph structures, offering deeper insights into network dynamics, and demonstrating that the whole is indeed greater than the sum of its parts.
