The size of each bubble corresponds to the term frequency. The data from the bubbles are as follows: Digital transformation: Year range: 22 to 24, Term frequency: 24. Bibliometric analysis: Year range: Not given, Term frequency: 24. Industry 4.0: Year range: 20 to 24, Term frequency: 23. Human resource management (hrm): Year range: 22 to 24, Term frequency: 23. 0: Year range: 20 to 23, Term frequency: 22. Industry 4: Year range: 20 to 23, Term frequency: 22. Human resource management: Year range: 20 to 22, Term frequency: 21. Education: Year range: 20 to 22, Term frequency: 21.
