The terms “robotics” and “internet of things” are named 52 and 49 times followed by
“advanced analytics” and “drones”.
As already discussed in the method section, the TF, especially the nominal TF, gives an
expanded view on the trends and allows further analyses. When looking at the average of the
nominal TF together with the PF the picture from the term occurrence can be validated as seen
in Figure 3. “Automation” occurs in 80% of all papers with a high FT value. Different from the
previous section, big data plays a significant role in 60% of the manuscripts with the second
highest TF. In total, the diagram shows a connection between TF and PF in most cases. The
term “drones” is mentioned in 40% of the white paper but with only 13% of a nominal TF.
