About this paper
Ulugbek Ergashev, Eduard C. Dragut, Weiyi Meng
FedGNN, a method combining pre-trained language models and graph neural networks, improves resource selection in distributed information retrieval. It substantially outperformed existing methods, achieving up to 42% improvement in nDCG@10 on the FedWeb14 dataset.
Key insights
- Combining pre-trained language models for semantic understanding with graph neural networks for structural modeling significantly enhances resource selection accuracy.
- Modeling both query-resource relationships and resource-resource similarities is crucial for effective distributed information retrieval, as demonstrated by ablation studies.
- Utilizing rich document representations from BERT, including both title and body text, improves performance over simpler embedding methods.
