iCite Database Snapshot 2024-01

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]

此乃iCite网络服务之数据库快照（此处提供单一压缩的CSV文件，或压缩并打包的JSON文件）。此外，NIH开放引文集合中的引文链接亦以两列CSV表格形式提供于open_citation_collection.zip中。iCite提供PubMed索引出版物之计量学及元数据，并分为三大模块：影响力模块：提供科学影响力的指标，经领域调整并以NIH出版物作为基准进行基准化。翻译模块：衡量每篇论文在人体、动物或分子/细胞生物学导向方面的程度；追踪并预测临床文章的引文。开放引文模块：传播来自NIH开放引文集合的逐链接、公有领域引文数据。各数据字段定义如下：
pmid：PubMed标识符，由美国国家医学图书馆在PubMed中分配的文章ID。
doi：数字对象标识符，如有。
year：出版年份。
title：文章标题。
authors：作者名单。
journal：期刊名称（ISO缩写）。
is_research_article：标志位，指示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。经领域调整、时间调整，并与NIH资助的论文进行比较。任何领域NIH资助论文的中位RCR为1.0。RCR为2.0表示该论文每年收到的引用数是同领域、同年NIH资助论文的中位数的两倍，而RCR为0.5则表示其每年收到的引用数仅为中位数的一半。计算细节请参考Hutchins等人的研究，发表在PLoS Biol. 2016；14(9)：e1002541。
provisional：前两年发表的论文的RCR标记为“临时”，以反映较新文章的引文指标可能不如旧文章稳定。对于前一年发表的论文，若其已获得5次或以上引用，即使许多情况下未满一年，也将提供临时RCR。上一年度及之前所有发表的论文均获得临时RCR。当前年度被视为NIH财政年度，始于10月。例如，2019年7月（NIH财政年度2019年），若2018年发表的论文有5次或以上引用，则将获得临时RCR，而所有2017年发表的论文也将获得临时RCR。2019年10月，NIH财政年度2020年开始，若2019年发表的论文有5次或以上引用，则将获得临时RCR，而所有2018年发表的论文也将获得临时RCR。
citation_count：引用该文章的唯一文章数量。
citations_per_year：自出版以来每年收到的引用数。如果该文章曾作为预印本发表，后又以正式文章发表，则使用正式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：该论文所属领域的内在引文率，通过其共引网络进行估算。
expected_citations_per_year：与该论文具有相同领域引文率和同年发表的NIH资助论文每年收到的引用数。这是相对引文比的分母。
nih_percentile：该论文RCR相对于所有NIH出版物的百分位排名。例如，95%表示该论文的RCR高于95%的NIH资助出版物。
human：属于人体类别的MeSH术语占该文章MeSH术语的比例（在属于人体、动物或分子/细胞生物学类别的MeSH术语中）。
animal：属于动物类别的MeSH术语占该文章MeSH术语的比例（在属于人体、动物或分子/细胞生物学类别的MeSH术语中）。
molecular_cellular：属于分子/细胞生物学类别的MeSH术语占该文章MeSH术语的比例（在属于人体、动物或分子/细胞生物学类别的MeSH术语中）。
x_coord：该文章在生物医药三角的X坐标。
y_coord：该文章在生物医药三角的Y坐标。
is_clinical：标志位，指示该论文是否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：近似潜在翻译能力，基于机器学习的估算，指该出版物在未来临床试验或指南中被引用的可能性。计算细节请参考Hutchins等人的研究，发表在PLoS Biol. 2019；17(10)：e3000416。
cited_by：引用该文章的文章的PMID。
references：该文章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，该版本比某些常见Linux发行版的默认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，如7zip进行解压。
