A formal comparison of physician notes on HIV patients with MEDCIN was carried out. Terms from patient charts were divided into five groups: History, Physical Examination, Symptoms, Diagnosis and Doctor's Orders. Four types of matches were determined: Exact, Lexical, Semantic and No-Match. Across the five groups, exact matches ranged from 12 to 44 percent, lexical matches from 2 to 11 percent, semantic matches from 9 to 21 percent, and no-matches from 29 to 74 percent.
对医生记录的艾滋病患者病历与医学知识体系（MEDCIN）进行了正式比较。患者病历中的术语分为五组：病史、体格检查、症状、诊断和医嘱。确定了四种匹配类型：完全匹配、词汇匹配、语义匹配和不匹配。在这五组中，完全匹配的比例在12%至44%之间，词汇匹配的比例在2%至11%之间，语义匹配的比例在9%至21%之间，不匹配的比例在29%至74%之间。
