HotelQuEST: Balancing Quality and Efficiency in Agentic Search (2026.eacl-industry)
Copied to clipboard
| Challenge: | Existing benchmarks for agentic search focus primarily on answer quality, overlooking efficiency factors that are critical for real-world deployment. |
| Approach: | They propose a benchmark for hotel search queries that includes 214 hotel query queries that range from simple factual requests to complex queries. |
| Outcome: | The proposed benchmarks show that LLM-based agents achieve higher accuracy than traditional retrievers, but at substantially higher costs due to redundant tool calls and suboptimal routing that fails to match query complexity to model capability. |
Quality Matters: Evaluating Synthetic Data for Tool-Using LLMs (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods to assess data quality for training and testing large language models are lacking. |
| Approach: | They propose two approaches to assess the reliability of data for training large language models for external tool usage. |
| Outcome: | The proposed approaches outperform models trained on high-quality data on two popular benchmarks and an extrinsic evaluation that showcases the impact of data quality on model performance. |
