BuyTheBy - An annotated dataset of paper mill advertisements with price data

The study of paper mills and similar businesses operating in the market for academic and education fraud services is frustrated by the lack of market price data on their various offerings. Here, we assemble BuyTheBy, a large, annotated dataset of timestamped, text-based paper mill advertisements from seven businesses operating out of seven different countries. The dataset consists of 18,710 individual advertisements, of which 15,839 have prices listed. Among these there are 20,598 positions listed as for sale on 5,567 unique products in 14 different product categories with 51,812 timestamped price data points. A preprint describing this dataset is available on arXiv.Code for reproducing figures and summary statistics is available at https://github.com/reeserich/buytheby.针对学术与教育造假服务市场中运营的论文工厂（paper mill）及同类机构的相关研究，因缺乏其各类服务的市场价格数据而进展受阻。在此，我们构建了BuyTheBy数据集：这是一个大规模带标注的数据集，涵盖来自7个不同国家的7家机构的、带有时间戳的文本型论文工厂广告数据。该数据集共包含18710条独立广告，其中15839条标注了价格。在这些带价格的广告中，共涉及14个不同产品类别下的5567种独特商品，累计上架20598个可售商品位，附带51812条带时间戳的价格数据。 本数据集的预印本可在arXiv平台获取。用于复现图表与汇总统计量的代码已开源，地址为https://github.com/reeserich/buytheby。
