This describes the output file for the CoronaCentral data. The scripts used to create it are hosted in the corona-ml Github repo. The sources for the documents before processing for CoronaCentral are PubMed and CORD-19. The file is a gzipped JSON document containing one record per document. Each document has at least one of: a PubMed ID, a CORD-19 ID (cord_uid), a DOI or a URL. The fields that documents should have are: pubmed_id: PubMed identifier (optional) pmcid: PubMed Central identifier (optional) doi: Digital object identifier (optional) cord_uid: CORD-19 identifier (optional) url: URL journal: Journal/preprint server publish_year: Year of publication (optional) publish_month: Month of publication (optional) publish_day: Day of publication (optional) title: Title of article abstract: Abstract of article (optional) is_preprint: Whether the article is a preprint topics: Predicted topics for article articletypes: Predicted article types for article entities: Extracted entities (e.g. drugs) with identifiers and locations within text Please report issues to the corona-ml Github issues page.本说明用于介绍CoronaCentral数据集的输出文件。用于生成该文件的脚本托管于corona-ml的GitHub代码仓库中。在用于CoronaCentral数据集的预处理流程前，相关文献的来源为PubMed与CORD-19数据库。该文件为经gzip压缩的JSON格式文档，每篇文献对应一条数据记录。每条文献记录至少包含以下标识之一：PubMed编号、CORD-19编号（cord_uid）、数字对象标识符（DOI）或统一资源定位符（URL）。文献记录应包含以下标准字段：pubmed_id：PubMed标识符（PubMed identifier），可选字段；pmcid：PubMed Central标识符（PubMed Central identifier），可选字段；doi：数字对象标识符（Digital Object Identifier，DOI），可选字段；cord_uid：CORD-19标识符（CORD-19 identifier），可选字段；url：统一资源定位符（Uniform Resource Locator，URL）；journal：期刊/预印本服务器名称；publish_year：出版年份，可选字段；publish_month：出版月份，可选字段；publish_day：出版日期，可选字段；title：文献标题；abstract：文献摘要，可选字段；is_preprint：标识该文献是否为预印本；topics：文献的预测主题；articletypes：文献的预测文章类型；entities：提取得到的实体（如药物），包含其标识符与在文本中的位置信息。若需反馈问题，请前往corona-ml的GitHub问题提交页面。
