Understanding how scientific knowledge develops requires more than merely counting papers and citations. It requires a careful evaluation of how research topics and themes interconnect and transform over time. This is where bibliometric analysis becomes essential. As the volume of scientific journals and papers continues to grow exponentially, bibliometric analyses ...
