摘要:

虽然人类可以从非结构化文本中提取具有高精度和高召回率的信息,但这通常太耗时而不实用。另一方面,自动化方法几乎可以立即产生结果,但对于精度至关重要的高风险应用来说可能不够可靠。在这项工作中,我们认为各种人的优点和缺点,只有人机,只有机器的信息抽取方法。我们主张在需要高精度的应用程序中使用人在回路方法,但纯手动提取是不可行的。我们提出了一个框架和一个附带的工具,信息抽取使用弱监督标签与人类验证。我们在三个刑事司法数据集上展示了我们的方法。我们发现,计算机速度和人类理解的结合产生了与手动注释相当的精度,同时只需要一小部分时间,并且在精度方面明显优于完全自动化的基线。

英文摘要:

While humans can extract information from unstructured text with high precision and recall, this is often too time-consuming to be practical. Automated approaches, on the other hand, produce nearly-immediate results, but may not be reliable enough for high-stakes applications where precision is essential. In this work, we consider the benefits and drawbacks of various human-only, human-machine, and machine-only information extraction approaches. We argue for the utility of a human-in-the-loop approach in applications where high precision is required, but purely manual extraction is infeasible. We present a framework and an accompanying tool for information extraction using weak-supervision labelling with human validation. We demonstrate our approach on three criminal justice datasets. We find that the combination of computer speed and human understanding yields precision comparable to manual annotation while requiring only a fraction of time, and significantly outperforms fully automated baselines in terms of precision.
