Model Performance and Trade-offs
While KG augmentation significantly improved general quality and attribute relevance across models, a trade-off was observed in linguistic fluency and coherence in some instances. This suggests the need for careful prompt engineering and knowledge representation to optimize all dimensions.
Qwen's Progressive Gains with KG Augmentation
The Qwen model demonstrated progressively stronger performance gains in general quality and attribute relevance with increasing task complexity when augmented with the curriculum KG. This highlights how structured knowledge provides effective semantic scaffolding for higher-complexity reasoning tasks, aligning with the theoretical view that KG augmentation enhances domain adaptability and reduces generative uncertainty.
