iCite Database Snapshot 2021-11

This is a database snapshot of the iCite web service (provided here as a single zipped CSV file, or compressed, tarred JSON files). In addition, citation links in the NIH Open Citation Collection are provided as a two-column CSV table in open_citation_collection.zip. iCite provides bibliometrics and metadata on publications indexed in PubMed, organized into three modules:Influence: Delivers metrics of scientific influence, field-adjusted and benchmarked to NIH publications as the baseline.Translation: Measures how Human, Animal, or Molecular/Cellular Biology-oriented each paper is; tracks and predicts citation by clinical articlesOpen Cites: Disseminates link-level, public-domain citation data from the NIH Open Citation CollectionDefinitions for individual data fields:pmid: PubMed Identifier, an article ID as assigned in PubMed by the National Library of Medicinedoi: Digital Object Identifier, if availableyear: Year the article was publishedtitle: Title of the articleauthors: List of author namesjournal: Journal name (ISO abbreviation)is_research_article: Flag indicating whether the Publication Type tags for this article are consistent with that of a primary research articlerelative_citation_ratio: Relative Citation Ratio (RCR)--OPA's metric of scientific influence. Field-adjusted, time-adjusted and benchmarked against NIH-funded papers. The median RCR for NIH funded papers in any field is 1.0. An RCR of 2.0 means a paper is receiving twice as many citations per year than the median NIH funded paper in its field and year, while an RCR of 0.5 means that it is receiving half as many citations per year. Calculation details are documented in Hutchins et al., PLoS Biol. 2016;14(9):e1002541.provisional: RCRs for papers published in the previous two years are flagged as "provisional", to reflect that citation metrics for newer articles are not necessarily as stable as they are for older articles. Provisional RCRs are provided for papers published previous year, if they have received with 5 citations or more, despite being, in many cases, less than a year old. All papers published the year before the previous year receive provisional RCRs. The current year is considered to be the NIH Fiscal Year which starts in October. For example, in July 2019 (NIH Fiscal Year 2019), papers from 2018 receive provisional RCRs if they have 5 citations or more, and all papers from 2017 receive provisional RCRs. In October 2019, at the start of NIH Fiscal Year 2020, papers from 2019 receive provisional RCRs if they have 5 citations or more and all papers from 2018 receive provisional RCRs.citation_count: Number of unique articles that have cited this onecitations_per_year: Citations per year that this article has received since its publication. If this appeared as a preprint and a published article, the year from the published version is used as the primary publication date. This is the numerator for the Relative Citation Ratio.field_citation_rate: Measure of the intrinsic citation rate of this paper's field, estimated using its co-citation network.expected_citations_per_year: Citations per year that NIH-funded articles, with the same Field Citation Rate and published in the same year as this paper, receive. This is the denominator for the Relative Citation Ratio.nih_percentile: Percentile rank of this paper's RCR compared to all NIH publications. For example, 95% indicates that this paper's RCR is higher than 95% of all NIH funded publications.human: Fraction of MeSH terms that are in the Human category (out of this article's MeSH terms that fall into the Human, Animal, or Molecular/Cellular Biology categories)animal: Fraction of MeSH terms that are in the Animal category (out of this article's MeSH terms that fall into the Human, Animal, or Molecular/Cellular Biology categories)molecular_cellular: Fraction of MeSH terms that are in the Molecular/Cellular Biology category (out of this article's MeSH terms that fall into the Human, Animal, or Molecular/Cellular Biology categories)x_coord: X coordinate of the article on the Triangle of Biomediciney_coord: Y Coordinate of the article on the Triangle of Biomedicineis_clinical: Flag indicating that this paper meets the definition of a clinical article.cited_by_clin: PMIDs of clinical articles that this article has been cited by.apt: Approximate Potential to Translate is a machine learning-based estimate of the likelihood that this publication will be cited in later clinical trials or guidelines. Calculation details are documented in Hutchins et al., PLoS Biol. 2019;17(10):e3000416.cited_by: PMIDs of articles that have cited this one.references: PMIDs of articles in this article's reference list.Large CSV files are zipped using zip version 4.5, which is more recent than the default unzip command line utility in some common Linux distributions. These files can be unzipped with tools that support version 4.5 or later such as 7zip.Comments and questions can be addressed to [e-mail]

此为iCite网络服务数据库的快照（提供为单个压缩的CSV文件，或压缩、打包的JSON文件）。此外，NIH开放引文集合中的引文链接以两列CSV表格的形式提供于open_citation_collection.zip文件中。iCite提供PubMed索引出版物中的计量学和元数据，分为三个模块：影响力：提供科学影响力的指标，经过领域调整并与NIH出版物基准对比；翻译：衡量每篇论文在人类、动物或分子/细胞生物学导向方面的程度；跟踪和预测临床文章的引文；开放引文：传播来自NIH开放引文集合的逐级、公共领域引文数据。各数据字段定义如下：
pmid：PubMed标识符，由美国国立医学图书馆在PubMed中分配的文章ID；doi：数字对象标识符，如有；year：文章发表年份；title：文章标题；authors：作者名单；journal：期刊名称（ISO缩写）；is_research_article：标志表明该文章的出版物类型标签是否与主要研究文章一致；relative_citation_ratio：相对引文比（RCR）--OPA的科学影响力指标。经过领域调整、时间调整并与NIH资助的论文基准对比；provisional：过去两年内发表的文章的RCR标记为“临时”，以反映新文章的引文指标可能不如旧文章稳定。对于前一年发表的、收到5次或更多引用的文章，提供临时RCR；citation_count：引用此文章的独特文章数量；citations_per_year：自文章发表以来每年收到的引用次数。如果此文章作为预印本和已发表文章出现，则以发表版本的年份作为主要出版日期。这是相对引文比的分母；field_citation_rate：本文所在领域的内在引文率，通过其共引网络估计；expected_citations_per_year：与本文具有相同领域引文率和同年发表的国家卫生研究院资助文章每年收到的引用次数。这是相对引文比的分母；nih_percentile：本文RCR相对于所有NIH出版物的百分位数排名。例如，95%表示本文的RCR高于95%的NIH资助出版物；human：属于人类类别的MeSH术语所占比例（占本文的MeSH术语中属于人类、动物或分子/细胞生物学类别的术语比例）；animal：属于动物类别的MeSH术语所占比例（占本文的MeSH术语中属于人类、动物或分子/细胞生物学类别的术语比例）；molecular_cellular：属于分子/细胞生物学类别的MeSH术语所占比例（占本文的MeSH术语中属于人类、动物或分子/细胞生物学类别的术语比例）；x_coord：文章在生物医药三角上的X坐标；y_coord：文章在生物医药三角上的Y坐标；is_clinical：标志表明该文章符合临床文章的定义；cited_by_clin：引用该文章的临床文章的PMID；apt：近似翻译潜力，是一种基于机器学习的估计，指该出版物在未来的临床试验或指南中被引用的可能性。计算细节记录在Hutchins等人，PLoS Biol. 2019;17(10):e3000416一文中；cited_by：引用该文章的文章的PMID；references：本文参考文献列表中文章的PMID。大型CSV文件使用zip版本4.5进行压缩，这比某些常见Linux发行版中默认的unzip命令行工具更新。这些文件可以使用支持版本4.5或更高版本的工具解压，如7zip。有关评论和问题，请联系[e-mail]。
