摘要:

文本数据的机器阅读理解(MRC)是自然语言理解的一个重要任务。这是一个复杂的NLP问题,随着斯坦福问答数据集(SQuAD)和会话式问答(CoQA)的发布,许多研究正在进行中。它被认为是教计算机如何“理解”文本,然后能够使用深度学习回答有关文本的问题的努力。然而,到目前为止,关于私人文本数据和知识共享的大规模培训一直缺乏这个NLP任务。因此,我们提出了FedQAS,这是一个保护隐私的机器阅读系统,能够利用大规模的私有数据,而不需要将这些数据集集中在一个中心位置。该方法结合了Transformer模型和联邦学习技术。该系统使用FEDn框架开发,并作为概念验证联盟计划部署。FedQAS是灵活的,语言无关的,并允许直观的参与和执行本地模型训练。此外,我们提出了该系统的架构和实现,以及提供一个基于SQUAD数据集的参考评估,以展示它如何克服数据隐私问题,并在联邦学习环境中实现联盟成员之间的知识共享。

英文摘要:

Machine reading comprehension (MRC) of text data is one important task in Natural Language Understanding. It is a complex NLP problem with a lot of ongoing research fueled by the release of the Stanford Question Answering Dataset (SQuAD) and Conversational Question Answering (CoQA). It is considered to be an effort to teach computers how to "understand" a text, and then to be able to answer questions about it using deep learning. However, until now large-scale training on private text data and knowledge sharing has been missing for this NLP task. Hence, we present FedQAS, a privacy-preserving machine reading system capable of leveraging large-scale private data without the need to pool those datasets in a central location. The proposed approach combines transformer models and federated learning technologies. The system is developed using the FEDn framework and deployed as a proof-of-concept alliance initiative. FedQAS is flexible, language-agnostic, and allows intuitive participation and execution of local model training. In addition, we present the architecture and implementation of the system, as well as provide a reference evaluation based on the SQUAD dataset, to showcase how it overcomes data privacy issues and enables knowledge sharing between alliance members in a Federated learning setting.
