Impact and co‑publication indicators are based on Web of Science publications only.

Overall Web of Science coverage for peer reviewed publications in this unit is moderate, 64.2%.

Background

The bibliometric indicators referred are based on publications registered in DiVA. Only publications from currently employed researchers at KTH are included. The rolling nature of this report means that it provides more of a current overview and less of a historic stable trend, since it excludes publications written by researchers that are no longer affiliated to KTH, but have been at some point in time.

Statistics regarding citations and co‑publishing are based on the subset of publications in DiVA that are registered in Web of Science.

The Open Access type of the publications was fetched from the Unpaywall REST API. The method to determine the OA type is presented here.

In summary, the different OA types can be described as follows:

  • Gold: The full text has been found on a publisher website, in a journal that is fully OA.

  • Hybrid: The full text has been found on a publisher website, in a journal that is not fully OA.

  • Green: The full text has been found in an institutional repository, such as DiVA.

  • Bronze: The full text has been found on a publisher website but no OA license could be identified.

N.B.: This table is based on peer-reviewed publications for which Unpaywall could determine the OA type (necessary condition: have a DOI number). Unpaywall’s method is empirical and does not strictly equate to copyright license. As a consequence, the OA status of a given publication may vary with time — for example turning from “Not OA” to “Green” when a full text is added to DiVA.
