DR^{3}-Eval: Towards Realistic and Reproducible Deep Research Evaluation

Hugging Face Daily Papers Papers

Summary

DR³-Eval is a benchmark for evaluating deep research agents on multimodal, multi-file report generation with a realistic web environment simulation and comprehensive evaluation framework measuring information recall, factual accuracy, citation coverage, instruction following, and depth quality.

Deep Research Agents (DRAs) aim to solve complex, long-horizon research tasks involving planning, retrieval, multimodal understanding, and report generation, yet their evaluation remains challenging due to dynamic web environments and ambiguous task definitions. We propose DR^{3}-Eval, a realistic and reproducible benchmark for evaluating deep research agents on multimodal, multi-file report generation. DR^{3}-Eval is constructed from authentic user-provided materials and paired with a per-task static research sandbox corpus that simulates open-web complexity while remaining fully verifiable, containing supportive documents, distractors, and noise. Moreover, we introduce a multi-dimensional evaluation framework measuring Information Recall, Factual Accuracy, Citation Coverage, Instruction Following, and Depth Quality, and validate its alignment with human judgments. Experiments with our developed multi-agent system DR^{3}-Agent based on multiple state-of-the-art language models demonstrate that DR^{3}-Eval is highly challenging and reveals critical failure modes in retrieval robustness and hallucination control. Our code and data are publicly available.

Abstract

DR^\{3\}-Eval is a benchmark for evaluating deep research agents on multimodal, multi-file report generation, featuring a realistic simulation of web environments and a comprehensive evaluation framework.

Deep Research Agents (https://huggingface.co/papers?q=Deep%20Research%20Agents)(DRAs) aim to solve complex, long-horizon research tasks involving planning, retrieval,multimodal understanding (https://huggingface.co/papers?q=multimodal%20understanding), andreport generation (https://huggingface.co/papers?q=report%20generation), yet their evaluation remains challenging due to dynamic web environments and ambiguous task definitions. We propose DR^{3}-Eval, a realistic and reproducible benchmark for evaluatingdeep research agents (https://huggingface.co/papers?q=deep%20research%20agents)on multimodal, multi-filereport generation (https://huggingface.co/papers?q=report%20generation). DR^{3}-Eval is constructed from authentic user-provided materials and paired with a per-task staticresearch sandbox corpus (https://huggingface.co/papers?q=research%20sandbox%20corpus)that simulates open-web complexity while remaining fully verifiable, containing supportive documents, distractors, and noise. Moreover, we introduce amulti-dimensional evaluation framework (https://huggingface.co/papers?q=multi-dimensional%20evaluation%20framework)measuringInformation Recall (https://huggingface.co/papers?q=Information%20Recall),Factual Accuracy (https://huggingface.co/papers?q=Factual%20Accuracy),Citation Coverage (https://huggingface.co/papers?q=Citation%20Coverage),Instruction Following (https://huggingface.co/papers?q=Instruction%20Following), andDepth Quality (https://huggingface.co/papers?q=Depth%20Quality), and validate its alignment with human judgments. Experiments with our developedmulti-agent system (https://huggingface.co/papers?q=multi-agent%20system)DR^{3}-Agent based on multiplestate-of-the-art language models (https://huggingface.co/papers?q=state-of-the-art%20language%20models)demonstrate that DR^{3}-Eval is highly challenging and reveals critical failure modes in retrieval robustness andhallucination control (https://huggingface.co/papers?q=hallucination%20control). Our code and data are publicly available.

DuMate-DeepResearch: An Auditable Multi-Agent System with Recursive Search and Rubric-Grounded Reasoning

arXiv cs.AI

This technical report introduces DuMate-DeepResearch, a multi-agent framework for deep research tasks that decouples the agent core from a tool ecosystem, and incorporates graph-based dynamic planning, recursive two-level execution, and rubric-based test-time optimization. The system achieves state-of-the-art results on two deep research benchmarks, demonstrating the value of auditable agent infrastructure.

Self-Evolving Deep Research via Joint Generation and Evaluation

arXiv cs.CL

Researchers from HKUST, ByteDance, and UCL propose SCORE, a co-evolutionary training framework that jointly trains an LLM as both a deep research report generator and an evaluator, using a meta-harness to dynamically adjust evaluation difficulty and prevent reward saturation. Experiments show consistent improvement in open-ended research report quality.
