Directional Queries: Making Top-k Queries More Effective in Discovering Relevant Results

Summary: Directional queries add a distance term to linear top-k, biasing toward balanced, skyline-like results aligned with attribute weights. Introduces four skyline-robustness and difficulty indicators and shows that the approach retrieves more relevant results with modest overhead on real and synthetic data.
