摘要:

我们提出了一个全面的工作,自动准确性评估从数据集创建到开发基于自然语言推理(NLI)的新方法,重点是与COVID-19大流行有关的错误信息。我们首先描述了新PANACEA数据集的构建,该数据集由关于COVID-19的异质声明及其各自的信息源组成。数据集的构建包括检索技术和相似性测量方面的工作,以确保一套独特的索赔。然后,我们提出了新的技术,自动准确性评估的基础上自然语言推理,包括图卷积网络和注意力为基础的方法。我们使用所提出的技术对数据集进行了证据检索和准确性评估的实验,发现它们与SOTA方法具有竞争力,并提供了详细的讨论。

英文摘要:

We present a comprehensive work on automated veracity assessment from dataset creation to developing novel methods based on Natural Language Inference (NLI), focusing on misinformation related to the COVID-19 pandemic. We first describe the construction of the novel PANACEA dataset consisting of heterogeneous claims on COVID-19 and their respective information sources. The dataset construction includes work on retrieval techniques and similarity measurements to ensure a unique set of claims. We then propose novel techniques for automated veracity assessment based on Natural Language Inference including graph convolutional networks and attention based approaches. We have carried out experiments on evidence retrieval and veracity assessment on the dataset using the proposed techniques and found them competitive with SOTA methods, and provided a detailed discussion.
