English(EN) Text-to-SQL Accuracy Isn't a Model Problem. It's a Schema Problem.

Text-to-SQL 准确性取决于模式,而非仅仅模型能力

dbt Labs 的一项最新分析强调,text-to-SQL 模型的准确性在很大程度上受到底层数据库模式的质量和结构的影响,而不仅仅是模型的能力。实验表明,即使没有语义层,改进模式设计也能将准确性从 64.5% 提高到 90.0%。使用语义层进行进一步增强可产生更好的结果。该研究还指出,不同的基准测试可能衡量不同的方面,例如模式翻译的难度或评分的宽松度,从而导致看似矛盾的结果。 AI

影响 强调了数据建模和模式设计对于有效的人工智能驱动的数据查询至关重要。

    Text-to-SQL 准确性不是模型问题,而是模式问题。

    <p><strong>TLDR:</strong> dbt Labs ran the same eleven questions four different ways and found that <em>modelling the schema</em> — with no semantic layer involved at all — moved text-to-SQL accuracy from 64.5% to 90.0%. Adding a semantic layer on top of that modelled schema move…
