🤖 AI Summary
Dataset quality defects—such as missing documentation, incorrect labels, and ethical risks—are pervasive in open platforms yet resistant to detection by rule-based scripts, necessitating intelligent, automated identification methods.
Method: We introduce the first LLM-agent benchmark for discovering real-world dataset quality issues, covering 221 empirically validated cases across eight platforms. It uniquely evaluates agents’ ability to autonomously detect latent defects without prior prompting. We propose an automated evaluation framework powered by GPT-4o, achieving high agreement with human experts (Cohen’s κ = 0.89), and ensure benchmark reliability via multi-source real-data sampling and expert annotation.
Contribution/Results: Experiments reveal that even the state-of-the-art Curator agent detects only ~30% of defects, underscoring task difficulty. All benchmark data, code, and evaluation tools are publicly released to advance intelligent data governance.
📝 Abstract
The quality of datasets plays an increasingly crucial role in the research and development of modern artificial intelligence (AI). Despite the proliferation of open dataset platforms nowadays, data quality issues, such as incomplete documentation, inaccurate labels, ethical concerns, and outdated information, remain common in widely used datasets. Furthermore, these issues are often subtle and difficult to be detected by rule-based scripts, therefore requiring identification and verification by dataset users or maintainers--a process that is both time-consuming and prone to human mistakes. With the surging ability of large language models (LLM), it's promising to streamline the discovery of hidden dataset issues with LLM agents. To achieve this, one significant challenge is enabling LLM agents to detect issues in the wild rather than simply fixing known ones. In this work, we establish a benchmark to measure LLM agent's ability to tackle this challenge. We carefully curate 221 real-world test cases from eight popular dataset platforms and propose an automatic evaluation framework using GPT-4o. Our proposed framework shows strong empirical alignment with expert evaluations, validated through extensive comparisons with human annotations. Without any hints, most competitive Curator agent can only reveal $sim$30% of the data quality issues in the proposed dataset, highlighting the complexity of this task and indicating that applying LLM agents to real-world dataset curation still requires further in-depth exploration and innovation.
