Structured information extraction from complex scientific text with fine-tuned large language models

Kavli Affiliate: Kristin Persson | First 5 Authors: Alexander Dunn, John Dagdelen, Nicholas Walker, Sanghoon Lee, Andrew S. Rosen | Summary: Intelligently extracting and linking complex scientific information from unstructured text is a challenging endeavor particularly for those inexperienced with natural language processing. Here, we present a simple sequence-to-sequence approach to joint named entity recognition […]
