A successful medical informatics program helps its users to match their information needs as closely and efficiently as possible to the capabilities of the system. CHARTLINE is a computer program whose input is a free text, "natural language" patient chart in ASCII format. Using the UMLS Metathesaurus Knowledge Sources, CHARTLINE can suggest bibliographic references relevant to the patient case described in the chart. The program does not attempt to "understand" the natural language content of the chart. CHARTLINE only recognizes UMLS Metathesaurus Main Concept terms (or their synonyms) as they occur in the medical text, since those terms represent the tokens used to index the literature. The program depends on user feedback to determine which topics of a large number of potentially relevant subjects are of interest to the user.
一个成功的医学信息学程序能帮助其用户尽可能紧密且高效地将他们的信息需求与系统功能相匹配。CHARTLINE是一个计算机程序，其输入是一个以ASCII格式呈现的自由文本、“自然语言”患者病历。利用统一医学语言系统（UMLS）元词表知识源，CHARTLINE可以推荐与病历中描述的患者病例相关的文献参考。该程序并不试图“理解”病历的自然语言内容。CHARTLINE仅识别医学文本中出现的UMLS元词表主要概念术语（或其同义词），因为这些术语代表用于索引文献的标记。该程序依靠用户反馈来确定大量潜在相关主题中哪些是用户感兴趣的。
