AI总结:

本文通过深度学习流程从历史报纸扫描件中重建了1878-1977年间270万篇美国新闻通讯社文章,构建了含地理参照、主题标注和实体消歧的大规模结构化数据集Newswire,可用于大语言建模及多学科研究。

摘要:

在美国历史上,地方报纸的内容主要来自美联社(Associated Press)等新闻通讯社。历史学家认为,新闻通讯社在塑造国家认同和共同的世界认知方面发挥了关键作用,但目前没有对通过新闻通讯社发送的内容的全面档案。我们通过将定制的深度学习流程应用于来自数千家地方报纸的数百TB原始图像扫描件,重建了这样一个档案。由此产生的数据集包含270万篇独特的美国公有领域新闻通讯社文章,写作时间在1878年至1977年之间。这些文章中的地点经过地理参照,主题使用定制的神经主题分类进行标注,命名实体被识别,个人通过一种新颖的实体消歧模型与维基百科进行消歧。为了构建Newswire数据集,我们首先识别报纸版面布局,并从原始图像扫描件中转录约1.38亿篇结构化文章文本。然后,我们使用定制的神经双编码器模型对转载文章进行去重,在存在大量删节和噪声的情况下,量化每篇文章被转载的广泛程度。使用文本分类器确保我们只收录新闻通讯社文章,这些文章在历史上属于公有领域。伴随文本的结构化数据提供了关于一个世纪以来数百万美国人阅读的新闻中“谁”(消歧后的个人)、“什么”(主题)和“哪里”(地理参照)的丰富信息。我们还收录了美国国会图书馆关于在头版刊登这些文章的报纸的元数据信息。Newswire数据集既可用于大语言建模——将训练数据扩展到现代网络文本所能提供的范围之外——也可用于研究计算语言学、社会科学和数字人文中的各种问题。

英文摘要:

In the U.S. historically, local newspapers drew their content largely from newswires like the Associated Press. Historians argue that newswires played a pivotal role in creating a national identity and shared understanding of the world, but there is no comprehensive archive of the content sent over newswires. We reconstruct such an archive by applying a customized deep learning pipeline to hundreds of terabytes of raw image scans from thousands of local newspapers. The resulting dataset contains 2.7 million unique public domain U.S. newswire articles, written between 1878 and 1977. Locations in these articles are georeferenced, topics are tagged using customized neural topic classification, named entities are recognized, and individuals are disambiguated to Wikipedia using a novel entity disambiguation model. To construct the Newswire dataset, we first recognize newspaper layouts and transcribe around 138 millions structured article texts from raw image scans. We then use a customized neural bi-encoder model to de-duplicate reproduced articles, in the presence of considerable abridgement and noise, quantifying how widely each article was reproduced. A text classifier is used to ensure that we only include newswire articles, which historically are in the public domain. The structured data that accompany the texts provide rich information about the who (disambiguated individuals), what (topics), and where (georeferencing) of the news that millions of Americans read over the course of a century. We also include Library of Congress metadata information about the newspapers that ran the articles on their front pages. The Newswire dataset is useful both for large language modeling - expanding training data beyond what is available from modern web texts - and for studying a diversity of questions in computational linguistics, social science, and the digital humanities.
