Outline

This paper proposes a novel model, SG-KBQA, to address the issue of knowledge-based question answering (KBQA) where knowledge-based elements are invisible at test time. SG-KBQA enhances generalization performance by injecting schema context into entity retrieval and logical form generation, leveraging rich semantics and awareness of the knowledge-based structure. Experimental results demonstrate that SG-KBQA demonstrates strong generalization performance, outperforming state-of-the-art models across a variety of test settings on two commonly used benchmark datasets. The source code is available at https://github.com/gaosx2000/SG_KBQA .

Takeaways, Limitations

Takeaways:
A novel method to improve the generalization performance of KBQA by leveraging schema context is presented.
Achieve performance that surpasses existing cutting-edge models
Reproducibility and further research possible through open source code
Limitations:
Performance verification on datasets other than the two presented benchmark datasets is needed.
A more in-depth analysis of the effects of schema context is needed.
Performance evaluation in real application environments is required.
