The Nature Index 2017 Science Inc. is a database of author affiliations and institutional relationships. The index tracks contributions to articles published in a group of highly selective science journals, chosen by an independent group of active researchers. The index covers articles published during five years from 1 January 2012 to 31 December 2016 and ranks the top 100 corporate institutions by their cumulative collaborative work for 2012 to 2016. The index also lists the top 50 corporate institutions ranked by the number of academic institutions they have co-authored papers with in that period, as well as the top 50 academic institutions co-authoring papers with the largest number of corporate partners. IBM tops the index with the most collaborations with universities for the period. IBM has a long standing tradition in working with universities to train future generations of scientists with the skills necessary to meet industry demands. The findings from the Nature Science point to IBM’s commitment to students.
