[IRTalk] July 2017 edition of the Ranking Web of Repositories was cancelled

[Heila Pienaar]

--The July 2017 edition of the *Ranking Web of Repositories* was *cancelled*
after discovering many entries with a large number of webpages, exceeding
several times the global output of the institution. After inspection, we
realized the individual records (papers, thesis, chapters) were
producing a *very
large* number of webpages (different entries for authors, collection,
keywords), so it was impossible to use the "Presence" indicator as a proxy
of institutional commitment to the open access initiatives. It is not clear
if this is an intended action or it is a result of using new (?) management
software, but its impact is so important that radical actions were
needed. *(Updated
30 October 2017: The Ranking of Repositories has been cancelled
definitively)*.

          Regarding the *Ranking Web of Universities*, we decided (July
2017 edition) to reduce the weight of the presence indicator from previous
10% to only 5% in order to limit the impact of the big repos on the global
ranking of the universities. However, as several repositories are now
amounting for several *hundreds of thousands webpages* (duplicate contents,
abstracts only, salami documents, news archives, non-scientific items), a
stronger measure is required for future editions.

          For now and having effect on January 2018 edition, we are
considering giving value equals to zero (=0) in the* Presence* indicator to
those universities with a repository representing more than one third of
their total size of their domain (number of webpages according to Google).
This will marked as rank 88888.

          For now and having effect on January 2018 edition, we are
considering giving value equals to zero (=0) in the *Openness* indicator to
those universities with a Journal (or group, department, project, faculty,
university or similar non-personal) profile in the Top 10 Google Scholar
profiles of their institutional or email-domain filtered profiles. This
will marked as rank 77777.
          (Updated 30 October 2017. Further changes can be applied in new
revisions before next edition)
