摘要:

在过去的几十年里,社交媒体的重要性增加了许多倍,因为它帮助即使是来自世界上最偏远角落的人们保持联系。随着COVID-19大流行的肆虐,社交媒体变得比以往任何时候都更相关和更广泛地使用,与此同时,需要立即关注的假新闻和推文的传播再次出现。在本文中,我们描述了我们的假新闻检测系统,该系统自动识别与COVID-19相关的推文是“真实”还是“虚假”,作为CONSTRAINT COVID-19 Fake News Detection in English挑战赛的一部分。我们使用了一个由预训练模型组成的集成模型,帮助我们在排行榜上获得了第八名的位置。我们取得了0.9831的F1分数,而最高分数为0.9869。比赛结束后,我们已经能够通过在tweets中引入一种基于用户名句柄和链接域的新型启发式算法来大幅改进我们的系统,该算法获得了0.9883的F1分数,并在给定的数据集上获得了最先进的结果。

英文摘要:

The significance of social media has increased manifold in the past few decades as it helps people from even the most remote corners of the world stay connected. With the COVID-19 pandemic raging, social media has become more relevant and widely used than ever before, and along with this, there has been a resurgence in the circulation of fake news and tweets that demand immediate attention. In this paper, we describe our Fake News Detection system that automatically identifies whether a tweet related to COVID-19 is "real" or "fake", as a part of CONSTRAINT COVID19 Fake News Detection in English challenge. We have used an ensemble model consisting of pre-trained models that has helped us achieve a joint 8th position on the leader board. We have achieved an F1-score of 0.9831 against a top score of 0.9869. Post completion of the competition, we have been able to drastically improve our system by incorporating a novel heuristic algorithm based on username handles and link domains in tweets fetching an F1-score of 0.9883 and achieving state-of-the art results on the given dataset.
