FinTagging: Benchmarking LLMs for Extracting and Structuring Financial Information

In three linesFinTagging is a benchmark for evaluating LLMs on extracting and tagging financial data with XBRL. It decomposes the task into two stages: FinNI (financial numeric identification) and FinCL (mapping to full US GAAP taxonomy). Testing shows models generalize well in extraction but struggle significantly with fine-grained concept linking.
