Evolution of Secondary Studies in SE

For each identified secondary study performed in 2010, 2015 and 2020, we have assessed the type of study (e.g. systematic review, mapping study), whether it is qualitative or quantitative (or methodological), the number of authors performing the study, and rated the experience of the leading author based on their entry in DBLP. This provides a profile of the secondary studies published in these three years (in five leading software engineering journals), enabling an assessment of how the use of secondary studies has evolved in the period 2010-2020.
