NewB: 200,000+ Sentences for Political Bias Detection

Dartmouth College(达特茅斯学院)

AI总结:

本文提出包含超20万句子的NewB政治偏见数据集,涵盖11个新闻来源,通过训练深度学习模型预测句子来源并分析n-grams以揭示媒体对Trump的描绘,促进复杂政治偏见的NLP研究。

摘要:

我们提出了 Newspaper Bias Dataset(NewB),这是一个包含来自 11 个新闻来源关于 Donald Trump 的超过 200,000 个句子的文本语料库。以前的数据集将句子标记为自由派或保守派,而 NewB 涵盖了 11 个流行媒体来源的政治观点,比传统的二元分类系统捕捉到了更细致的政治观点。我们训练了两个最先进的深度学习模型来预测给定句子来自 11 家报纸中的哪个新闻来源,并发现循环神经网络分别达到了 33.3%、61.4% 和 77.6% 的 top-1、top-3 和 top-5 准确率,显著优于基线 logistic 回归模型 18.3%、42.6% 和 60.8% 的准确率。利用句子的新闻来源标签,我们用我们的模型分析了 top n-grams,以深入了解媒体来源对 Trump 的描绘。我们希望公开我们的数据集将鼓励进一步使用自然语言处理来分析更复杂的政治偏见的研究。我们的数据集发布在 https://github.com/JerryWeiAI/NewB 。

英文摘要:

We present the Newspaper Bias Dataset (NewB), a text corpus of more than 200,000 sentences from eleven news sources regarding Donald Trump. While previous datasets have labeled sentences as either liberal or conservative, NewB covers the political views of eleven popular media sources, capturing more nuanced political viewpoints than a traditional binary classification system does. We train two state-of-the-art deep learning models to predict the news source of a given sentence from eleven newspapers and find that a recurrent neural network achieved top-1, top-3, and top-5 accuracies of 33.3%, 61.4%, and 77.6%, respectively, significantly outperforming a baseline logistic regression model's accuracies of 18.3%, 42.6%, and 60.8%. Using the news source label of sentences, we analyze the top n-grams with our model to gain meaningful insight into the portrayal of Trump by media sources.We hope that the public release of our dataset will encourage further research in using natural language processing to analyze more complex political biases.
