• Using BD-FDG, a domain dataset named SSA-SFT was constructed, containing approximately 230,000 samples, and used to fine-tune Qwen3-8B into SSA-LLM-8B.result 70%
  Evidencepartial

  Using BD-FDG, we construct SSA-SFT, a domain dataset of approximately 230K samples, and fine-tune Qwen3-8B to obtain SSA-LLM-8B.

• BD-FDG is a framework designed to address challenges in creating high-quality supervised fine-tuning (SFT) datasets for domain adaptation of LLMs, specifically targeting incomplete knowledge coverage, shallow cognitive depth, and limited quality controllability.method 70%
  Evidencepartial

  To this end, we propose BD-FDG (Bloom's Taxonomy-based Domain-specific Fine-tuning Data Generation), a framework that addresses incomplete knowledge coverage, shallow cognitive depth, and limited quality controllability through three mechanisms: structured knowledge organization, cognitively layered question modeling, and automated quality control.

  Implicationpartial

  The abstract explicitly states the purpose and mechanisms of the BD-FDG framework in addressing these specific challenges.
