Tag-Instruct: Controlled Instruction Complexity Enhancement through Structure-based Augmentation

ACL 2025finding

High-quality instruction data is crucial for developing large language models (LLMs), yet existing approaches struggle to effectively control instruction complexity. We present Tag-Instruct, a novel framework that enhances instruction complexity through structured semantic compression and controlled…
