In the following tag-clouding analysis,
co-terms are presented in an arbitrary
mode, while the calculation of tag frequencies
is similar to other established
tag-clouding algorithms.38 Each graph in
figures 1–8 contains all co-term distributions
in the required qualifications of one
year’s job descriptions. With eight graphs
in a chronological order from 2005 to 2012,
we can easily detect the consistency of
employers’ desire for personal characters,
communication and management
skills (that is, “communication skills”
and “project management” abilities) of
job candidates as were discovered in
the analysis of co-term frequencies in
required job qualifications (see table 11).
This consistency is observable throughout
time. Also as mentioned above, the visual
results by no means devalue employers’
emphasis on the requirements of technical
competencies, which are relatively
underrepresented due to the diverse
