Researchers from DS@GT HIPE have developed a lightweight system for extracting person-place relationships from historical newspapers, focusing on interpretability and efficiency. Their approach utilizes dependency graphs and proximity features, classifying relations with small scikit-learn ensembles or compact Graph Attention Networks, keeping model parameters under 847K. The system achieved a macro recall of 0.5142 on the HIPE-2026 shared task, ranking third for efficiency, and highlighted the importance of minimum character distance for capturing classification signals. The study also emphasized the necessity of document-grouped cross-validation to prevent data leakage. AI
IMPACT This research demonstrates an efficient and interpretable approach to relation extraction, potentially reducing the computational cost for historical text analysis.
