Enhancing Generative Information Extraction with Two-step Validation: A Product Attribute Use Case

This work proposes a two-step validation method that integrates a PLM block into the generative IE pipeline and thereby leverages LLMs' correction capability, discovering that such a validation task enhances LLM performance, particularly on the extraction of weakly expressed, low-salience entities that appear sparsely throughout the text.
