Polarity and Sentiment Analysis of Medical Transplant Literature

The comparative analysis of three flagship medical journals from different specialties show that (i) strongly polar words are relatively common in medical research papers, (ii) each specialty has its own main polar words; (iii) transplant medicine favors words reflecting the stress of the discipline, with specifically high frequency for words such as ‘challenging’, ‘demanding’, ‘risk’, ‘human error’, and ‘danger’, and an emphasis on ‘decision-making’.
