• The size of the font is proportional to the frequency the word appears in the titles

• Words without semantic meaning were suppressed (e.g., the, and, for, study and analysis).

• The most frequent words in all fields received relatively smaller weights in the analysis of each field in particular.

• This filter was not applied in the multidisciplinary field.
