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.本文用于说明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。在用于构建CoronaCentral数据集前，原始文档的来源为PubMed与CORD-19。该文件为经gzip压缩的JSON文档，每篇文档对应一条记录。单篇文档至少包含以下四类标识之一：PubMed编号、CORD-19编号（cord_uid）、数字对象标识符（Digital Object Identifier，DOI）或统一资源定位符（Uniform Resource Locator，URL）。文档应包含的字段如下：pubmed_id：PubMed标识符（可选）；pmcid：PubMed Central标识符（可选）；doi：数字对象标识符（Digital Object Identifier，DOI，可选）；cord_uid：CORD-19标识符（可选）；url：统一资源定位符（URL）；journal：期刊/预印本服务平台；publish_year：发表年份（可选）；publish_month：发表月份（可选）；publish_day：发表日期（可选）；title：文章标题；abstract：文章摘要（可选）；is_preprint：用于标识该文章是否为预印本的字段；topics：为文章预测得到的主题分类；articletypes：为文章预测得到的文章类型分类；entities：提取得到的实体（如药物），附带其标识符及在原文中的位置信息。若需反馈问题，请提交至corona-ml的GitHub issues页面。
