Efficient Discovery of Motif Transition Process for Large-Scale Temporal Graphs
This work addresses the need for efficient analysis of dynamic graph structures for applications like pattern identification and behavior prediction, representing a strong specific gain in computational performance.
The paper tackles the problem of discovering motif transition processes in large-scale temporal graphs, proposing PTMT, a parallel algorithm that achieves speedups of 12.0× to 50.3× compared to the state-of-the-art method on 10 real-world datasets.
Understanding the dynamic transition of motifs in temporal graphs is essential for revealing how graph structures evolve over time, identifying critical patterns, and predicting future behaviors, yet existing methods often focus on predefined motifs, limiting their ability to comprehensively capture transitions and interrelationships. We propose a parallel motif transition process discovery algorithm, PTMT, a novel parallel method for discovering motif transition processes in large-scale temporal graphs. PTMT integrates a tree-based framework with the temporal zone partitioning (TZP) strategy, which partitions temporal graphs by time and structure while preserving lossless motif transitions and enabling massive parallelism. PTMT comprises three phases: growth zone parallel expansion, overlap-aware result aggregation, and deterministic encoding of motif transitions, ensuring accurate tracking of dynamic transitions and interactions. Results on 10 real-world datasets demonstrate that PTMT achieves speedups ranging from 12.0$\times$ to 50.3$\times$ compared to the SOTA method.
