SoREX: Towards Self-Explainable Social Recommendation with Relevant Ego-Path Extraction
SoREX: Bridging Accuracy and Transparency in Social Recommendations
GNN-based social recommendation excels in accuracy but lacks explainability, hindering user trust and transparency.
Introduces a self-explainable framework with a two-tower GNN architecture, ego-path extraction for explanations, and multi-task learning for robust social signals.
Novel ego-path extraction for factor-specific and candidate-aware explanations, re-aggregation for prediction correlation, and a friend recommendation auxiliary task.
Achieves superior predictive accuracy on four benchmarks and provides verifiable, comparative explanations, enhancing system transparency and user engagement.

Comparative Explanation in Action
A detailed case study revealed how SoREX identifies different ego-paths and similarity distributions for positive vs. negative samples. For a target user, the interaction tower highlighted common neighborhoods, while the social tower emphasized closer social connections for a recommended item. This allows for clear, factor-specific justifications for ranking decisions, even for items without direct shared connections. For instance, item V4 was recommended over V1 and V2 due to a 'shorter, socially meaningful path via direct friend U4', showcasing structural signals' interpretative power. This demonstrates SoREX's ability to provide nuanced comparative reasoning, explaining 'why this item over others' based purely on graph structures.
