TL;DR
Real-world networks are often incomplete and complex, making analysis challenging. The Spreading-Oriented Reduction Benchmark (SORB) was developed to evaluate influence maximization (IM) models while incorporating graph reduction techniques.
✦ Why It Matters
Engineers can leverage SORB to better understand how graph reduction impacts influence maximization in their network analyses.
Key Takeaways
Full Summary
Real-world networks, such as social or information networks, are typically incomplete and noisy, complicating their analysis. Influence maximization (IM) aims to identify key nodes to maximize information spread, but the impact of graph reduction as a preprocessing step has not been thoroughly examined.
The Spreading-Oriented Reduction Benchmark (SORB) was created as an open-source framework to systematically evaluate IM models across various network types and tasks. SORB integrates graph reduction into the evaluation process, allowing for a more nuanced understanding of how these reductions affect IM outcomes.
The study found that sparsification, a reduction technique, maintains seed set quality in single-layer networks, while multilayer networks experience ranking degradation regardless of the reduction method used. These findings emphasize the need for reduction-aware evaluations in complex network studies, particularly for applications in social and information networks.
