In linking Iliad to an electronic medical record (EMR) as a knowledge server, our objective is to convert the date and time stamped data from the EMR to the temporal representations existing in the Iliad knowledge base. First, an empirical analysis of Iliad's temporal information content is described: categorizing, estimating the amount (22%), and offering a temporal template to canonically represent it. Second, we analyze the effect of history and physical examination temporal information on the diagnostic performance of the system using data from 241 real cases. Third, we discuss knowledge engineering mapping techniques to convert time information found in EMRs. We conclude that the Iliad system includes a large amount of explicit and implicit time information and this information improves the system's diagnostic accuracy, both in terms of diagnosis ranking and confidence.
在将《伊利亚特》（Iliad）作为知识服务器与电子病历（EMR）相连接时，我们的目标是将电子病历中带有日期和时间戳的数据转换为《伊利亚特》知识库中现有的时间表示形式。首先，描述了对《伊利亚特》时间信息内容的实证分析：进行分类、估计数量（22%）并提供一个时间模板以规范地表示它。其次，我们使用来自241个真实病例的数据，分析病史和体格检查时间信息对系统诊断性能的影响。第三，我们讨论将电子病历中发现的时间信息进行转换的知识工程映射技术。我们得出结论，《伊利亚特》系统包含大量明确和隐含的时间信息，并且这些信息在诊断排名和置信度方面都提高了系统的诊断准确性。
