New benchmark ANT-A and framework ANT-OR improve LLM annotation consistency

Researchers have introduced the ANT-A Benchmark to address limitations in current LLM annotation benchmarks, which often fail to account for the nuanced and sometimes divergent judgments of human annotators. This new benchmark includes task-specific guidelines and five independent human labels per instance across seven diverse datasets. To improve LLM annotation systems, they also proposed ANT-OR, a multi-agent framework that refines prompts using contrastive decision rules derived from feedback, showing a 4.5-point improvement in agreement accuracy over baseline methods.

IMPACT This research could lead to more robust and adaptable LLM annotation systems that better reflect real-world human judgment.

    Can LLM Annotators Match Human Consistency? Benchmarking Human Agreement and Optimizing Multi-Agent with Contrastive Knowledge

    arXiv:2610.32415v1 Announce Type: new Abstract: LLM-based annotation has advanced rapidly, yet existing benchmarks remain misaligned with real-world practice. Actual annotation often involves lengthy, task-specific guidelines, and different annotators may produce divergent but re…
