Abstract
Protein–protein interaction (PPI) networks play a crucial role in understanding cellular processes, disease mechanisms, and drug discovery. Topology-based models have emerged as powerful tools for analysing the structural and functional organization of these networks by leveraging graph theory, network science, and topological data analysis. This systematic review examines advances from 2018 to 2023 in topology-based modelling of PPI networks, focusing on methodologies, computational architectures, and emerging research directions. The review explores classical graph-theoretic approaches, including centrality measures, clustering, and modularity detection, alongside advanced techniques such as persistent homology, network embedding, and graph neural networks (GNNs). Special attention is given to algorithms for protein complex detection, topological scoring, and multi-scale network analysis. The findings indicate that while traditional topological models provide strong interpretability and biological relevance, modern hybrid approaches integrating machine learning and topological features significantly enhance prediction accuracy and scalability. However, challenges remain in handling noisy datasets, dynamic interactions, and computational complexity. Future research directions include topology-driven deep learning frameworks, multi-layer biological networks, and interpretable AI models for PPI analysis. This review provides a comprehensive foundation for developing next-generation topology-aware computational frameworks in systems biology.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
