Counting citations that a research article received by other articles was the traditional bibliometric method for the evaluation of a scientific research. Citations have been used both to evaluate a scientific paper - usually in conjunction with the peer review methods - and to determine the quality of a scientific research output. The development of tools even more Web 2.0 oriented has profoundly changed the scientific communication process. In this context, many web tools have emerged including the so-called "social media" (e-i., Facebook, Twitter). Hence the need for new indicators to measure the influence of these tools on the scientific community and the emergence of alternative metrics. Altmetrics combines the traditional bibliometrics tool with the use of the web. Formulated with the purpose to measure new aspects of scientific production, these new metrics are placed in order to complement and supplement the existing indicators rather than act as their replacements.
统计一篇研究论文被其他论文引用的次数是评估科学研究的传统文献计量方法。引用既被用于评估一篇科学论文——通常与同行评审方法结合使用——也被用于确定科学研究产出的质量。更具Web 2.0导向的工具的发展深刻地改变了科学交流过程。在这种背景下，许多网络工具出现了，包括所谓的“社交媒体”（如Facebook、Twitter）。因此，需要新的指标来衡量这些工具对科学界的影响，替代计量应运而生。替代计量将传统文献计量工具与网络的使用结合起来。这些新指标旨在衡量科学产出的新方面，其目的是补充和完善现有指标，而不是取代它们。
