How to expand first names of a Bib(la)TeX entry

Sometimes, one has a Bib(la)TeX entry with abbreviated short names:

@Article{Eshuis_2015,
author = {R. Eshuis and A. Norta and O. Kopp and E. Pitkanen},
journal = {{IEEE} Transactions on Services Computing},
title = {Service Outsourcing with Process Views},
year = {2015},
month = {jan},
number = {1},
pages = {136--154},
volume = {8},
publisher = {Institute of Electrical and Electronics Engineers ({IEEE})},
}

Now, one wants to have the full first names. In case, there is a DOI available, this is as simple as the following steps:

  1. Determine the DOI: Switch to the "General" tab and click on "Look up DOI"
