KTH co-publishing per country, 2015-2019

The statistics reported at this page and its subpages have been compiled by the bibliometric group at the KTH Library, KTH Royal Institute of Technology.

The table below gives the number of co-published articles for KTH in combination with other, relative to Sweden, countries. The articles that underlie the tables are published in the period 2015-2019. For year 2019, the publication data are not complete.

Data and differences between research fields

Only articles recorded in Web of Science, of the types 'Article' or 'Review' and with at least one KTH affiliation, have been taken into account. This resulted in a total of 12,283 articles of which 8,526 have been internationally co-published (69%). Note that publications in the humanities, social sciences and in fields, where proceedings papers are frequent, are covered by Web of Science to a considerably smaller extent compared to the natural sciences. This should be kept in mind when interpreting the results shown on these pages.

Counting method

Many of the co-published articles involve a large number of authors and countries, for instance articles in particle physics. For countries that have a lot of such articles co-published with KTH, their total number of co-published articles gives a somewhat misleading picture of the strength of their collaboration with KTH. Therefore, the statistics is divided into categories depending on the number of authors of the articles and in total (the column “Total full”). The column “Total frac” gives the number of publication (address) fractions across the number-of-authors categories. The table is sorted descending after “Total frac”, and not after “Total full”.

For instance, KTH and China have co-published 2,279 articles, of which 196 have 11-50 authors. The total number of publication fractions for KTH and China is equal to 821.86. If China has one of four addresses in a publication co-published with KTH, this publication contributes with the publication fraction 1/4 to the total number of publication fractions for KTH and China.

Note that, for all tables and for all numerical columns except the ones that concerns publication fractions, a publication co-published by KTH and two or more countries other than Sweden is counted one time for each such country.

Links to further tables

The five leftmost columns of the table are populated with links. The link “Per subject category” for China, for example, leads to a table, where the number of articles co-published by China and KTH by Web of Science Subject Category, and by number-of-authors category, is given. The column “Total (pub. and subject frac)” gives the total number of publication fractions for KTH and China in the Web of Science Subject Categories, and across the number-of-authors categories. Here, a fraction for a publication is obtained by multiplying the country publication fraction by the subject category fraction. The latter is calculated as 1/k, where k is the number of subject categories the publication belongs to.

The links “Per year”, “Per country organization”, “Per KTH School” and “Per KTH Researcher” lead to tables that report the number of articles co-published by KTH and a country by publication year, organization within a country, KTH School and KTH researcher, respectively, and by number-of-authors category. Also these tables have a column that contains publication fractions in total.

Unification of organization names

For the table with number of articles per country, organization within countries and number-of authors category, all organization names have not yet been consistently unified. Therefore, more than one row in the table, for a given country, might have organization names that refer to one and the same organization.
