A preliminary Study of Knowledge Sharing related to Covid-19 Pandemic in Stack Overflow

The Covid-19 outbreak has changed to an unprecedented extent almost every aspect of human activity. At the same time, the pandemic has stimulated enormous amount of research by scientists across various disciplines, seeking to study the phenomenon itself, its epidemiological characteristics and ways to confront its consequences. Information Technology, and particularly Data Science, drive innovation in all related to Covid-19 biomedical fields. Acknowledging that software developers routinely resort to open ‘question & answer’ communities like Stack Overflow to seek advice on solving technical issues, we have performed an empirical study to investigate the extent, evolution and characteristics of Covid-19 related posts. Through the study of 464 Stack Overflow questions posted in February and March 2020 and leveraging the power of text mining, we attempt to shed light into the interest of developers in Covid-19 related topics and the most popular problems for which the users seek information. The findings reveal that indeed this global crisis sparked off an intense activity in Stack Overflow with most post topics reflecting a strong interest on the analysis of Covid- 19 data, primarily using Python technologies.
