尽管相关性判断是设计和评价所有信息检索系统的基础，但信息学家在定义相关性这一核心概念方面尚未达成共识。本文重新审视了该领域主要作家的观点，并介绍了一种新的研究方法。我们认为，相关性是一个多层面的概念；它基于人的判断过程；它依赖于内部(认知)和外部(情景)因素；它是主观间的，但仍然是系统的和可衡量的。我们提出了一种不同于经典的源到目的通信模型的信息检索范式。这种以用户为中心的认知模型将用户而不是系统视为相关性维度的中心和积极的决定因素。
Although relevance judgments are fundamental to the design and evaluation of all information retrieval systems, information scientists have not reached a consensus in defining the central concept of relevance. This paper re-examines the viewpoints of major writers in the field, then introduces a new approach. We believe that relevance is a multidimensional concept; that it is based on the human judgment process; that it is dependent on both internal (cognitive) and external (situational) factors; and that it is intersubjective but nevertheless systematic and measurable. We suggest a different paradigm from the classic source-to-destination communication model of information retrieval. This user-centric cognitive model views the user not the system -as the central and active determinant of the dimensions of relevance.
