This research aims to enhance machine reading comprehension by effectively integrating long-distance entity relations and linguistic cues.
Developed an entity-graph-enhanced MRC framework using graph convolutional networks to process entity co-occurrence graphs.
Created two graph construction strategies: sentence-level co-occurrence and sliding-window co-occurrence using normalized pointwise mutual information.
Conducted experiments on the DuReader dataset to compare model performances against baselines including BERT.
The proposed framework shows consistent improvements over BERT, PERT, and MacBERT in BLEU-4 and ROUGE-L metrics.
The sliding-window graph construction method demonstrates the best performance overall.
Enhancements reflect the significance of entity relationships in improving MRC tasks.
