Query: Google Scholar Metrics evolution: an analysis according to languages   In November 2012 the Google Scholar Metrics (GSM) journal rankings were
updated, making it possible to compare bibliometric indicators in the 10
languages indexed and their stability with the April 2012 version. The h-index
and h 5 median of 1000 journals were analysed, comparing their averages,
maximum and minimum values and the correlation coefficient within rankings. The
bibliometric figures grew significantly. In just seven and a half months the h
index of the journals increased by 15% and the median h-index by 17%. This
growth was observed for all the bibliometric indicators analysed and for
practically every journal. However, we found significant differences in growth
rates depending on the language in which the journal is published. Moreover,
the journal rankings seem to be stable between April and November, reinforcing
the credibility of the data held by Google Scholar and the reliability of the
GSM journal rankings, despite the uncontrolled growth of Google Scholar. Based
on the findings of this study we suggest, firstly, that Google should upgrade
its rankings at least semiannually and, secondly, that the results should be
displayed in each ranking proportionally to the number of journals indexed by
language
