The value and credits of n-authors publications
share
Collaboration among researchers is becoming increasingly common, which raises a large number of scientometrics questions for which there is not a clear and generally accepted answer. For instance, what value should be given to a two author or three author publication with respect to a single author publication? This paper proposes a practical method to compute the expected value of an n authors publication that takes into consideration the added value induced by collaboration in contexts in which there is no prior or ex ante information about the publication potential merits or scientific impact. The only information required is the number of authors. We compared the obtained theoretical values with the empirical values based on a large dataset from the Web of Science database. We found that the theoretical values are very close to the empirical values for some disciplines, but not for all. This observation provides support in favor of the method proposed in this paper. We expect that our findings can help researchers and decision makers to choose more effective and fair counting methods that take into account the benefits of collaboration.
