This research paper introduces GPAM, a novel framework for few-shot relation extraction with NOTA (none-of-the-above), addressing the challenges of limited data and unknown relation classification by employing Gaussian prototype and adaptive margin techniques.
This work introduces a meta dataset for few-shot relation extraction that captures realistic real-world scenarios, and conducts a comprehensive evaluation of six recent few-shot relation extraction methods, revealing the need for substantial future research in this domain.
Large language models can achieve competitive performance in few-shot relation extraction tasks using the CoT-ER approach, which incorporates explicit evidence reasoning.
