Researchers from The University of Hong Kong and Microsoft Research Asia developed AnnoLLM, an LLM-powered system that functions as a data annotator and generator using an "explain-then-annotate" strategy. This method enabled large language models to surpass human crowdsourcers on one task and match human performance on another, while also producing a high-quality dataset for conversational information retrieval.

Key insights

  • LLMs can consistently produce high-quality, relevant explanations for labels when guided by ground truth, significantly enhancing their annotation capabilities.
  • The "explain-then-annotate" strategy is more effective than standard few-shot prompting, improving accuracy and leveraging LLMs' reasoning potential in data annotation.
  • AnnoLLM's CoT prompts enhance annotation stability, making the LLM less sensitive to minor variations in prompt templates and providing more robust performance.
