Academic evaluation is often intertwined with various subjective and objective complex factors. Because academic evaluation is often affected by the evaluation subjects' academic views, emotional tendencies, values and other factors, people tend to rely on quantitative data for evaluation. In fact, the evaluation significance contained in this kind of data is reflected by clickers, downloaders and citators. Over reliance on such data is to regard the producer of quantitative data as the evaluation subject.
The main idea of the above is that the evaluation system based on quantitative indicators is controversial.
