AI总结:

本研究探索用GPT-4等大语言模型,以零样本和含本体、少样本的上下文学习变体,通过增量问答从非结构化PDF提取过程,验证了方法潜力,为解决过程提取中训练数据不足的难题提供了新路径。

摘要:

自然语言处理领域的最新进展,尤其是在海量知识上预训练的大规模语言模型的发展,正在知识工程领域创造全新机遇。本文研究了大语言模型(LLMs)在零样本和上下文学习场景下的应用,以增量式问答的方式解决从非结构化PDF文本中提取过程的问题。具体而言,我们采用了当前最先进的GPT-4(生成式预训练Transformer 4)模型,并搭配两种上下文学习变体:一种引入包含过程和步骤定义的本体,另一种使用少量样本的少样本学习。研究结果既彰显了该方法的应用前景,也体现了上下文学习定制化的价值。这些改进有望显著解决获取充足训练数据的难题,而这正是基于深度学习的自然语言处理技术在过程提取任务中常遇到的障碍。

英文摘要:

Recent advancements in the field of Natural Language Processing, particularly the development of large-scale language models that are pretrained on vast amounts of knowledge, are creating novel opportunities within the realm of Knowledge Engineering. In this paper, we investigate the usage of large language models (LLMs) in both zero-shot and in-context learning settings to tackle the problem of extracting procedures from unstructured PDF text in an incremental question-answering fashion. In particular, we leverage the current state-of-the-art GPT-4 (Generative Pre-trained Transformer 4) model, accompanied by two variations of in-context learning that involve an ontology with definitions of procedures and steps and a limited number of samples of few-shot learning. The findings highlight both the promise of this approach and the value of the in-context learning customisations. These modifications have the potential to significantly address the challenge of obtaining sufficient training data, a hurdle often encountered in deep learning-based Natural Language Processing techniques for procedure extraction.
