Scientists’ Contribution to Science and Methods of Its Visualization

In the paper, fuzzy sets technology is used to find out the levels of the scientific contribution of a scientist or a team of scientists into scientific fields or discipline. Namely, fuzzy logic is applied to describe the fuzzy input and output relations between scientific fields, disciplines, journals and researchers, afterward, the compositions of these relations and the proposed optimistic fuzzy aggregation norm over fuzzy variables are used. Two techniques are applied to show the contribution to the science of the team of researchers graphically; one graphical method uses the radar graphs, and the other one is the application of the t-SNE technique based on the Euclidean metrics in the space of the scientists’ contribution into the different scientific fields. Moreover, the proposed methods are the foundation for the web-software “ScienceFuzz” developed for calculations levels of contribution to the sciences by an individual researcher or by a team of them.
