摘要:

大规模数字数据处理提供了广泛的机会和好处,但代价是危及个人数据隐私。匿名化包括从数据中删除或替换敏感信息,使其能够用于不同目的,同时保护个人隐私。多年来,已经提出了许多自动匿名化系统;然而,根据数据类型、目标语言或培训文档的可用性,任务仍然具有挑战性。在过去的两年中,新型深度学习模型的出现为自然语言处理领域的最新技术带来了巨大的进步。这些进步最明显的是由Google在2018年提出的模型BERT以及在数百万文档上预训练的共享语言模型。在本文中,我们使用一个基于BERT的序列标记模型进行了一系列的匿名化实验在西班牙语的几个临床数据集。我们还比较了BERT与其他算法。实验表明,一个简单的基于BERT的模型与一般领域的预训练获得了很高的竞争力的结果,没有任何特定领域的特征工程。

英文摘要:

Massive digital data processing provides a wide range of opportunities and benefits, but at the cost of endangering personal data privacy. Anonymisation consists in removing or replacing sensitive information from data, enabling its exploitation for different purposes while preserving the privacy of individuals. Over the years, a lot of automatic anonymisation systems have been proposed; however, depending on the type of data, the target language or the availability of training documents, the task remains challenging still. The emergence of novel deep-learning models during the last two years has brought large improvements to the state of the art in the field of Natural Language Processing. These advancements have been most noticeably led by BERT, a model proposed by Google in 2018, and the shared language models pre-trained on millions of documents. In this paper, we use a BERT-based sequence labelling model to conduct a series of anonymisation experiments on several clinical datasets in Spanish. We also compare BERT to other algorithms. The experiments show that a simple BERT-based model with general-domain pre-training obtains highly competitive results without any domain specific feature engineering.
