Taguchi design of experiments is a method used in
engineering, especially in the field of new product development,
for optimizing production processes and improving product
quality. The Taguchi method is widely used in the field of industrial
engineering. The purpose of this study is to investigate
the applicability of the Taguchi method for other tasks, such as
optimizing search results. Using the Taguchi method, we assess
the popularity of three names for COVID-19 that have been
used by scientists in research related to COVID-19 in the context
of Vietnam. The results show the positive value of using the
Taguchi method to optimize search results. The keyword
COVID-19 is found to be the most-used keyword. The results
also show that disease prevention, spread, infection, transmission,
treatments, preparation, and responses to the disease are
particularly interesting research topics in Vietnam at present.
