摘要:

数据效率,尽管是一个有吸引力的特性,通常是具有挑战性的测量和优化面向任务的语义解析;不像精确匹配,它可能需要模型和域特定的设置,这在历史上,在实验中有很大的差异。在我们的工作中,作为一个统一的解决方案,数据效率相关的问题的一步,我们引入了一个四阶段的协议,给出了一个近似的测量多少在域中,“目标”数据的解析器需要达到一定的质量酒吧。具体来说,我们的协议包括(1)对不同基数的目标子集进行采样,(2)对每个子集进行微调解析器,(3)获得一条关于目标子集(%)与精确匹配(%)的平滑曲线,以及(4)引用该曲线来挖掘ad-hoc(目标子集,精确匹配)点。我们应用我们的协议在两个现实世界的案例研究-模型的泛化和意图的复杂性-说明其灵活性和适用性,以面向任务的语义解析从业者。

英文摘要:

Data efficiency, despite being an attractive characteristic, is often challenging to measure and optimize for in task-oriented semantic parsing; unlike exact match, it can require both model- and domain-specific setups, which have, historically, varied widely across experiments. In our work, as a step towards providing a unified solution to data-efficiency-related questions, we introduce a four-stage protocol which gives an approximate measure of how much in-domain, "target" data a parser requires to achieve a certain quality bar. Specifically, our protocol consists of (1) sampling target subsets of different cardinalities, (2) fine-tuning parsers on each subset, (3) obtaining a smooth curve relating target subset (%) vs. exact match (%), and (4) referencing the curve to mine ad-hoc (target subset, exact match) points. We apply our protocol in two real-world case studies -- model generalizability and intent complexity -- illustrating its flexibility and applicability to practitioners in task-oriented semantic parsing.
