Practical Impact for Hadith Studies
Scenario: A Hadith scholar is curating a large collection of isnads and encounters ambiguous narrator names. Traditional methods often produce overconfident, incorrect links, requiring extensive manual review. EviLink-NA provides calibrated confidence scores and an 'abstain' option for low-evidence cases, significantly reducing false positives and directing human effort more efficiently.
Benefit: This allows scholars to trust automated suggestions more, focus manual review on genuinely uncertain cases, and maintain high data integrity in historical network analysis. The explicit evidence breakdown for each channel (text, time, geo, path, reliability) also enhances transparency and auditability.
EviLink-NA's ability to sharply reduce overconfident errors and support principled abstention makes it invaluable for digital Hadith curation. Its auditable uncertainty and risk-controllable coverage directly address scholarly needs.
Robustness to Missing Metadata
EviLink-NA maintains stable performance even with significant metadata dropout, crucial for real-world Hadith corpora.

Limitations and Future Work
The verifier assumes the correct identity is present in the Top-k pool. Future work includes uncertainty-aware retrieval, period-aware mobility priors, cross-collection linking under transliteration variation, and integrating GNN-based verifiers for end-to-end relational representation learning while preserving calibration.
