Bibliometric indicators have been devised to quantify scientific production and to try to evaluate its impact in the community. In general, bibliometric indicators can be classified according to whether the unit of analysis is the author (individual or group) or journal. The most widely used indicators for authors are those that measure an individual author's production, such as the Crown index or the h-index and its derivatives (e-index, h5-index, and the absolute or Ab-index, among others). The bibliometric indicators devised to try to evaluate journal quality are associated with Journal Citation Reports (e.g., impact factor, field-weighted citation impact, Eigenfactor, and article influence) or with Scopus (Scimago Journal Rank (SJR), source normalized impact per paper (SNIP), and CiteScore). This article describes the main bibliometric indicators, explains how they are calculated, and discusses their advantages and limitations.
文献计量指标被用来量化科学产出，并试图评估其在科学界的影响。一般来说，文献计量指标可以根据分析单位是作者（个人或团体）还是期刊来进行分类。最常用于评估作者的指标是那些衡量单个作者产出的指标，例如 Crown 指数或 h 指数及其衍生指标（如 e 指数、h5 指数和绝对 h 指数等）。为了评估期刊质量而设计的文献计量指标与期刊引证报告（例如，影响因子、领域加权引文影响力、特征因子和文章影响力）或 Scopus 相关（例如，Scimago 期刊排名（SJR）、归一化影响指标（SNIP）和 CiteScore）。本文介绍了主要的文献计量指标，解释了它们的计算方法，并讨论了它们的优缺点。
