Research Summary

Contribution Summary

• Efficient context compression is crucial for improving the accuracy and scalability of question answering.
• We propose a margin-based framework for query-driven context pruning, which identifies sentences that are critical for answering a query by measuring changes in clue richness when they are omitted.
• Built on a lightweight encoder-only Transformer, our approach generally achieves strong exact-match and F1 scores with high-throughput inference and lower memory requirements than those of major baselines.

Why It Matters For Eval

• Abstract shows limited direct human-feedback or evaluation-protocol detail; use as adjacent methodological context.
