Author Credit for Transdisciplinary Collaboration

<div><p>Transdisciplinary collaboration is the key for innovation. An evaluation mechanism is necessary to ensure that academic credit for this costly process can be allocated fairly among coauthors. This paper proposes a set of quantitative measures (e.g., t_credit and t_index) to reflect authors’ transdisciplinary contributions to publications. These measures are based on paper-topic probability distributions and author-topic probability distributions. We conduct an empirical analysis of the information retrieval domain which demonstrates that these measures effectively improve the results of harmonic_credit and h_index measures by taking into account the transdisciplinary contributions of authors. The definitions of t_credit and t_index provide a fair and effective way for research organizations to assign credit to authors of transdisciplinary publications.</p></div

Segmented cumulative counts of the 100 top-ranked authors based on harmonic_credit.

<p>Note: The segments are not separated evenly because tied ranking cases are not uncommon in ranking lists. In each cell, the number means the counts of authors who have the same rank range in both ranking list of harmonic_credit and ranking list of t_credit_sum, and the percentage in brackets means the percentage of the counts of authors who have the same range in both ranking list.</p><p>Segmented cumulative counts of the 100 top-ranked authors based on harmonic_credit.</p
