Unveiling Experts in Data Science: A Mining Software Repository Perspective (S)

Data science is a field of knowledge that exploits various methods of collecting and analyzing data.Nowadays, data-driven software development is getting more common and multiple experts take part of the process, such as data scientists and software developers.Nevertheless, locating professionals who possess strong technical skills as a data scientist may be a difficult task because such data are not easy to verify.This paper explores the activity of data scientists in software repositories, such as commits, to identify their technical skills.By analyzing 18 data science projects, we identified 69 data scientists.A data science proficiency measurement was then conducted by counting and categorizing the number and types of applied changes.Our results shows that 68% of the data scientists are mono languages; i.e., they use a single programming language (Python).
