This collection of R files were used in 2017 to collect, process, analyze and present basic metadata about doctoral dissertations available at NaRDus, National Repository of Doctoral Dissertations in Serbia. When the code was last used, there were nearly 6,000 dissertations in the database. Today, it is more than 10k. Context of the research is given in the paper "Транспарентност и отвореност података кроз стварање и развој националног репозиторијума докторских дисертација у Србији (НаРДуС)".
Word cloud obtained through the brief keywords' analysis show what PhD students in Serbia did for their doctoral research in a few years before 2017.
We would be happy to see new and more profound statistics.
