在基于Web的自适应系统中，通常向所有用户提供相同的评分表，以表达他们对各种项目的偏好。从我们最近进行的一项用户实验中发现，不同的用户在给定他们正在评估的特定主题的情况下，对于在自适应系统的界面中使用的评级尺度显示出不同的偏好。从这一发现出发，我们建议允许用户选择他们喜欢的评分标准。这种方法提出了各种问题；最重要的是自适应算法如何正确处理来自不同评级等级的值。我们进行了一项实验，以调查用户如何在不同的评分标准上对同一对象进行评分。基于我们对这些结果的解释，作为一个可能的解决方法的例子，我们提出了一个三阶段归一化过程，用于将以不同评级等级表达的偏好映射到唯一的系统表示上。
In web-based adaptive systems, the same rating scales are usually provided to all users for expressing their preferences with respect to various items. It emerged from a user experiment that we recently carried out that different users show different preferences with respect to the rating scales to use in the interface of adaptive systems, given the particular topic they are evaluating. Starting from this finding, we propose to allow users to choose the kind of rating scale they prefer. This approach raises various issues; the most important is that of how an adaptation algorithm can properly deal with values coming from heterogeneous rating scales. We conducted an experiment to investigate how users rate the same object on different rating scales. On the basis of our interpretation of these results, as an example of one possible solution approach, we propose a three-phase normalization process for mapping preferences expressed with different rating scales onto a unique system representation.
