LC-ICL: Label-Guided Contrastive In-Context Learning for Robust Information Extraction

arXiv:2606.29407v1 Announce Type: cross Abstract: There has been increasing interest in exploring the capabilities of advanced large language models (LLMs) in the field of information extraction (IE), specifically focusing on tasks related to named entity recognition (NER) and relation extraction (RE).Although researchers are exploring the use of few-shot information extraction through in-context learning with LLMs, they tend to focus only on using correct or positive examples for demonstration, neglecting the potential value of incorporating incorrect or negative examples into the learning pr

Why this matters
Why now

The increasing focus on maximizing the efficiency and robustness of LLMs for practical applications like information extraction drives continuous research into optimizing in-context learning techniques.

Why it’s important

Improving the accuracy and robustness of information extraction from unstructured text has broad implications for automating data processing, enhancing analytics, and building more reliable AI systems.

What changes

The proposed LC-ICL method offers a novel approach to in-context learning by integrating negative examples, potentially leading to more resilient and accurate information extraction compared to current positive-only demonstration methods.
