本文讨论了基于效用概念的相似推理的严密基础。如果效用是用数学术语表示的，它可以作为相似系统的形式规范。然而，效用也可以以非正式的方式表述。我们考虑主观版本、竞争版本和随时间动态变化的版本。风险分析、语音识别和城市规划的例子说明了这一点。从这些例子中，我们得出了一些挑战。
In this paper we discuss a rigorous foundation of similarity reasoning based on the concept of utility. If utility is formulated in mathematical terms it can serve as a formal specification for a similarity system. However, utility can also be formulated in informal ways. We consider subjective versions, competing ones and those that change dynamically over time. These are illustrated by examples from risk analysis, speech recognition, and urban planning. From the examples we derive a number of challenges.
