This study aims to support the expressions adjustment in teaching clinical research protocols through computer assistance by evaluating the accuracy of extracting medical and clinical trial-related terms using existing natural language processing (NLP) tools and the Unified Medical Language System (UMLS) developed by the U.S. National Library of Medicine as a dictionary. Of the 671 unique terms and 939 total terms that did not match the manual validation, 462 unique terms (68.9%) and 518 total terms (55.2%) were deemed improvable through rule-based methods.Addressing these statistical terms could be achieved by adding domain-specific terminology to the dictionary, although variations in expression, such as "detection rate" versus "statistical power" or "1-β," pose additional challenges.
