The Prize Winner Index (PWI): A proposal for an indicator based on scientific prizes

Abstract: In this study, we propose a new index for measuring performance in science which is based on collaborations (co-authorship distances) in science: the Prize Winner Index (PWI). The PWI is based on the Erdős number – a number that was introduced several years ago. We propose to focus with the new index on laureates of prestigious prizes in a certain field and to measure co-authorship distances between the laureates and other scientists. To exemplify and explain our proposal, we computed the proposed index in the field of quantitative science studies (PWIPM). The Derek de Solla Price Memorial Award (Price Medal, PM) is awarded to outstanding scientists in the field. We tested the convergent validity of the PWIPM. We were interested whether the indicator is related to two established bibliometric indicators: (1) citation impact (number of papers belonging to the 10 % most frequently cited), and (2) journal prestige (number of papers which have appeared in top quartile journals). The results show that the coefficients for the correlation between PWIPM and both indicators are high in cases when a sufficient number of papers have been considered for a reliable assessment of performance. Therefore, measured by established indicators for research performance, the new PWI indicator seems to be convergently valid and, therefore, might be a possible alternative for established (bibliometric) indicators – with a focus on prizes.
