Bonne analyse de l'Eigenfactor

Divergences sur la définition des Citable Document Types dans le WoS et dans Scopus, mais aussi à propos des paramètres du SNIP (Leiden + Scopus) et du SJR (Scimago + Scopus). Le Post est à la fois pertinent sur sa première partie mais contesté (avec raison) sur la seconde par un bibliométricien du CWTS, à l'origine du SNIP.

Pour la reconnaissance d'un profil professionnel de bibliométricien dans les filières de l'information-documentation

25 février 2016 En février, le CNRS a signé avec les géants de la bibliométrie, Thomson-Reuters et Elsevier, ses deux premiers accords-cadres en tant que centrale d'achat. Ils portent sur l'accès aux bases de données bibliographiques et citationnelles ainsi que sur les outils d'analyse. Une opération de mutualisation intéressante tant sur le plan scientifique qu'économique.

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%.

Analyse de la provenance des Full-Texts sur GS. Google Scholar, a widely used academic search engine, plays a major role in finding free full-text versions of articles. But little is known about the sources of full-text files in Google Scholar.

Le clone d'Arxiv en Bio : Un bon exemple d'Altmetrics sur un papier récent

Last week ORCID published the results of its first major survey. Around 6,000 respondents globally - ORCID record holders and non record holders - provided feedback on their perceptions

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.

Estimation du rapport entre le nombre de citations virtuellement récupérées à partir de la revue seule ou compte tenu d'une insertion complémentaire dans Academia.edu. Il faut les croire...

Vast numbers of scientific articles are published each year, some of which attract considerable attention, and some of which go almost unnoticed. Here, we investigate whether any of this variance can be explained by a simple metric of one aspect of the paper's presentation: the length of its title. Our analysis provides evidence that journals which publish papers with shorter titles receive more citations per paper. These results are consistent with the intriguing hypothesis that papers with shorter titles may be easier to understand, and hence attract more citations.
