自动索赔检测模型中的可检性:数据集的定义和分析

Checkworthiness in Automatic Claim Detection Models: Definitions and Analysis of Datasets

KU Leuven(鲁汶大学)

Liesbeth Allein, Marie-Francine Moens

摘要:

在过去的十年里,公众、专业人士和学术界对自动事实核查的兴趣急剧增加,许多人的目标是自动化事实核查程序的第一步:选择所谓的可核查的索赔。然而,事实检查员之间对可检查性的定义和特征几乎没有达成一致,因此反映在用于训练和测试可检查性索赔检测模型的数据集中。经过对事实核查组织中可核查性索赔选择程序的详细分析和对最先进的索赔检测数据集的分析,可核查性被定义为具有时空和上下文相关价值的概念,并且需要验证其传达的客观性的正确性。这与个人根据先前的知识和信念对索赔的感知真实性的判断无关。关于当前数据集的特点,有人认为,数据不仅是高度不平衡和噪音,而且在范围和语言上过于有限。此外,我们认为,检查价值的主观概念可能不是一个合适的过滤器索赔检测。

英文摘要:

Public, professional and academic interest in automated fact-checking has drastically increased over the past decade, with many aiming to automate one of the first steps in a fact-check procedure: the selection of so-called checkworthy claims. However, there is little agreement on the definition and characteristics of checkworthiness among fact-checkers, which is consequently reflected in the datasets used for training and testing checkworthy claim detection models. After elaborate analysis of checkworthy claim selection procedures in fact-check organisations and analysis of state-of-the-art claim detection datasets, checkworthiness is defined as the concept of having a spatiotemporal and context-dependent worth and need to have the correctness of the objectivity it conveys verified. This is irrespective of the claim's perceived veracity judgement by an individual based on prior knowledge and beliefs. Concerning the characteristics of current datasets, it is argued that the data is not only highly imbalanced and noisy, but also too limited in scope and language. Furthermore, we believe that the subjective concept of checkworthiness might not be a suitable filter for claim detection.
