CLUE: Using Large Language Models for Judging Document Usefulness in Web Search Evaluation
CLUE introduces a novel cascade LLM-based method for judging document usefulness, explicitly integrating user search context and behavior, outperforming traditional labeling and machine learning methods, and significantly enhancing user satisfaction prediction.
Executive Impact: Quantifying LLM-Driven Evaluation
The CLUE framework consistently outperforms third-party relevance annotations and existing machine learning models in usefulness judgment, achieving state-of-the-art results across various datasets. Notably, integrating CLUE's usefulness labels boosts user satisfaction prediction by over 11%, demonstrating significant practical value for enterprise evaluation systems.

CLUE Methodology
Usefulness vs. Relevance
LLM Evaluation Performance
Satisfaction Prediction
CLUE proposes a user-centric evaluation method employing a cascade structure for multilevel usefulness judgments. It leverages LLMs with rich behavior and context information through carefully designed prompts and a multi-voter mechanism to enhance robustness. Inspired by ordinal regression, it breaks down usefulness judgments into sequential binary classification tasks.
The paper highlights the critical distinction between document relevance and usefulness. Relevance focuses on objective topic matching, while usefulness captures user perception, task completion, and actual benefits derived from a document. CLUE prioritizes usefulness, explicitly incorporating user context to provide a more accurate reflection of user satisfaction.
CLUE significantly outperforms traditional third-party labeling and machine learning methods in usefulness judgment across various datasets. With GPT-4, it achieves moderate positive correlations and surpasses third-party annotations. Ablation studies confirm the effectiveness of its multi-voter mechanism and guideline integration.
A key contribution of CLUE is its ability to improve user satisfaction prediction. Real-world experiments using BaiduLog24Q3 data reveal that incorporating CLUE's LLM-driven usefulness labels significantly enhances satisfaction prediction models, outperforming models based solely on user behavior or traditional relevance labels.
CLUE's Cascade Usefulness Judgment Process
Input: Query, Clicked Documents & User Context
→
Stage 1: LLM selects C4 (Very Useful)
→
Stage 2: LLM selects C3 (Fairly Useful) from remaining
→
Stage 3: LLM selects C2 (Somewhat Useful) from remaining
→
Output: Remaining documents assigned to C1 (Not Useful)
| Feature | CLUE (Multi-Voter) | CLUE-s (Single Voter) |
|---|---|---|
| F1-Score (SIGIR16) | 0.3813 | 0.3663 |
| Spearman's Rho (SIGIR16) | 0.3816 | 0.3616 |
| Robustness to Document Order | High (Reduced Sensitivity) | Lower (Higher Sensitivity) |
| Error Reduction | Significant | More Prone to Errors |
User-Centric Guideline Impact
+6.7% F1-Score Increase with Guidelines (KDD19)Incorporating user-derived guidelines into LLM prompts leads to notable accuracy improvements, demonstrating the value of user-centric insights for usefulness judgment.
Enhanced Performance Through Fine-Tuning
Fine-tuning open-source LLMs significantly boosts their performance for usefulness judgments. For instance, Llama-3-FT achieves an F1-Score of 0.3576 on SIGIR16, a clear improvement over the base Llama-3's 0.3128 F1-Score, highlighting the effectiveness of creating specialized binary classifiers for cascade evaluation.
