AW: [SIGMETRICS] SV: [SIGMETRICS] World Shares of Publications of the USA, EU-27, and China Compared and Predicated using the New Interface of the Web-of-Science versus Scopus

[Haustein, Stefanie]

Dear Olle, dear Loet,

it is now even possible to obtain the world output without the workaround of the title query by searching for the publication year directly: "PY=2000-2010" should retrieve all documents published between 2000 and 2010. You should be able to use the analyze function on the result as well.

Loet, can you tell me, if there was a specific reason why you used tape years instead of publication years for the WoS data? Thanks!

Best,

Stefanie

good that you made me aware of new WoS having no max limit for record sets.
Made me make this


[cid:825243714 at 11102011-1985]

this comes reasonably close to NSI data from Thomson itself, although they count differently. Compare with page 26 in http://www.fpol.no/Forskningspolitikk/Lists/Research%20policy%20magazine/Attachments/30/Forskningspolitikk_3-2011.pdf

World output can be found using: TI=(A* OR B* OR C* OR D* OR E* OR F* OR G* OR H* OR I* OR J* OR K* OR L* OR M* OR N* OR O* OR P* OR Q* OR R* OR S* OR T* OR U* OR V* OR W* OR X* OR Y* OR Z*)
and then I used the Analyse function.....

Best

Olle

Compared and Predicated using the New Interface of the Web-of-Science versus Scopus<http://arxiv.org/ftp/arxiv/papers/1110/1110.1802.pdf>
The new interface of the Web of Science (of Thomson Reuters) enables users to retrieve sets larger than 100,000 documents in a single search. This makes it possible to compare publication trends for China, the USA, EU-27, and a number of smaller countries. China no longer grew exponentially during the 2000s, but linearly. Contrary to previous predictions on the basis of exponential growth or Scopus data, the cross-over of the lines for China and the USA is postponed to the next decade (after 2020) according to this data. These long extrapolations, however, should be used only as indicators and not as predictions. Along with the dynamics in the publication trends, one also has to take into account the dynamics of the databases used for the measurement.
