Excellente contribution de Fred Bordignon, probablement l'une des meilleures spécialistes de la bibliométrie actuellement.

Like a modern-day Protagoras, Elsevier has offered us CiteScore, a new metric for a community that likes nothing better than to add two numbers together. Some might wonder if we need a new metric, if we are not in fact already awash in metrics.

Which are the most important papers in the history of a field? On whose shoulders of giants does an author stand? Where to look for the intellectual roots of a research topic? These questions can be answered by using the program CitedReferencesExplorer (CRExplorer). The CRExplorer is a new software development which is based on the programs provided at Loet Leydesdorff's homepage.

Last Thursday, Elsevier announced CiteScore metrics, a free citation reporting service for the academic community. The primary metric promoted by this service is also aptly named CiteScore and is similar, in many ways, to the Impact Factor. Both CiteScore and the Impact Factor are journal-level indicators built around a ratio of citations to documents.

PLOS ONE is poised to lose its claim as the largest journal in the world soon, with rival journal, Scientific Reports, taking its place. Scientific Reports, published by Springer Nature was a relative latecomer to the scene, and, at the time of its launch, many skeptics did not believe that there would be room for yet another multidisciplinary open access journal.

Thomson Reuters Corp (TRI.TO) on Monday said it agreed to sell its intellectual property and science business to private equity firms Onex Corp (OCX.TO) and Baring Private Equity Asia for $3.55 billion in cash. The business, which has 3,200 employees, provides intellectual property and scientific information and associated tools and services to governments, universities and companies.

On April 17, as part of FORCE 2016 in Portland Oregon, Crossref, and THOR partners DataCite and ORCID convened a workshop to discuss the current state of the art in organisation identifiers. We discussed this issue previously in a post on the ORCID blog, and we're pleased to report back to you all that the...

Le CNRS est classé à la 5e place du nouveau classement de Thomson-Reuters des organismes publics les plus innovants au monde. Il figure aussi dans le Top 100 des innovateurs mondiaux, toujours publié par Thomson Reuters, ainsi que dans celui de l'Office européen des brevets (OEB)....Ce palmarès s'appuie sur les données relevant de la propriété intellectuelle et du nombre de brevets et de publications, répertoriées dans les bases de Thomson-Reuters ces huit dernières années.

Le Web of Science et le JCR n'ont pas les mêmes modalités de calcul de cumul de citations. Les calculs de médianes sur le JCR sont impossibles en raison de la dichotomie des deux produits. On reste bloqué sur des calculs de moyennes parce que le JCR ne permet pas de faire autre chose. Il se contente de mentionner à la marge l'Eigenfactor (sans l'expliquer) et le JIF percentile comme alternatives à ses calculs bruts.

Discussing the Journal Impact Factor inevitably leads one down a rabbit hole. While the numerator of the ratio (total citations) to the journal is clear enough, the denominator (citable items) causes great confusion, and getting a clear answer to its construction requires real work.

PLOS ONE's 2015 Impact Factor is expected to rise, the result of its shrinking size. As reported earlier this year, the open access mega-journal has experienced two successive declines in article output, from a peak of 31,509 research papers in 2013 to 28,107 in 2015-a reduction of 3,402 papers or 11%.

Is there a name for that sensation that "it seemed like yesterday ... and yet, also, forever ago"? That's how I felt on learning that it's already / only five years since the " altmetrics manifesto" was published. At last week's 2:AM conference in Amsterdam, the authors of that manifesto were brought together in person for the first time.

by César Villamizar and Heather Morrison In May 2015 we conducted a pilot study correlating OA APCs and the journal impact factor, using data from 2010, 2013 and 2014. Here are some early results: about 10% of the journals listed in JCR are DOAJ journals over 10% of the journals listed in DOAJ have an...
