传统的主题相关性概念在检索系统的评估中可以做很多有用的工作，但对于检索系统的完整评估有局限性。虽然主题相关性可以有效地评估各种索引和检索方法，但它对于衡量系统对用户的影响却无效。另一种方法是使用更加情境化的相关性定义，它考虑到系统对用户的影响。这两种类型的相关性都从医学领域的角度进行了审查，得出的结论是每种都有其适当的用途。但在医学领域，人们越来越重视以结果为导向的研究，当将其应用于信息科学时，需要评估信息系统对促进其使用的活动的影响。提出了检索评估的迭代模型，首先使用主题相关性来确保可以检索有关该主题的文档。接下来是使用情境相关性来表明用户可以与系统进行积极的交互。最后一步是研究系统如何影响用户以达到咨询系统的目的，这可以通过协议分析和仿真等方法来完成。这些不同类型的研究对于增进我们对检索系统本质的理解是必要的。 © 1994 约翰威利父子公司。
The traditional notion of topical relevance has allowed much useful work to be done in the evaluation of retrieval systems, but has limitations for complete assessment of retrieval systems. While topical relevance can be effective in evaluating various indexing and retrieval approaches, it is ineffective for measuring the impact that systems have on users. An alternative is to use a more situational definition of relevance, which takes account of the impact of the system on the user. Both types of relevance are examined from the standpoint of the medical domain, concluding that each have their appropriate use. But in medicine there is increasing emphasis on outcomes‐oriented research which, when applied to information science, requires that the impact of an information system on the activities which prompt its use be assessed. An iterative model of retrieval evaluation is proposed, starting first with the use of topical relevance to insure documents on the subject can be retrieved. This is followed by the use of situational relevance to show the user can interact positively with the system. The final step is to study how the system impacts the user in the purpose for which the system was consulted, which can be done by methods such as protocol analysis and simulation. These diverse types of studies are necessary to increase our understanding of the nature of retrieval systems. © 1994 John Wiley & Sons, Inc.
