Lectura recomendada. A finales del pasado mes, 28 de enero de 2016, en el blog Google Scholar Digest se publicó una interesante entrada sobre los nuevos Altmetrics (Authors Level Metrics), titulada A new Altmetrics; bibliometricians in Google Scholar Citación, ResearcherID, ResearchGate, Mendeley, and Twitter: measuring those who count, cuyos autores son Juan Manuel Ayllón Millán, Emilio Delgado López-Cózar, Alberto Martín Martín y Enrique Orduña Malea. Se trata de un estudio innovador que persigue, según los propios autores,
This study presents, for the first time, a comparison of 31 author-level bibliometric indicators: number of publications, number of citations, usage (views and downloads of bibliographic records and documents), social media presence (tweets) and connectivity (followers/following). These indicators were extracted from various platforms such as GSC (Google Scholar Citations), ResearcherID, ResearchGate, Mendeley, and Twitter. Each of these platforms was designed for a different purpose, and they use different data sources.
Our goal is to learn what each of these indicators can tell us about the researchers. We studied their correlation to learn what they measure and the extent to which each of the indicators is similar or different to the rest. We compared authors, not articles, like it is usually done. With this we open the door to a new ALMetrics: Authors Level Metrics, an assessment of the performance of authors in the scientific Web, whether it be thorough the information found on bibliographic databases, academic search engines, specialized or institutional repositories, or social media.
