We consider interactive tools that help users search for their most preferred
item in a large collection of options. In particular, we examine
example-critiquing, a technique for enabling users to incrementally construct
preference models by critiquing example options that are presented to them. We
present novel techniques for improving the example-critiquing technology by
adding suggestions to its displayed options. Such suggestions are calculated
based on an analysis of users current preference model and their potential
hidden preferences. We evaluate the performance of our model-based suggestion
techniques with both synthetic and real users. Results show that such
suggestions are highly attractive to users and can stimulate them to express
more preferences to improve the chance of identifying their most preferred item
by up to 78%.

本文探讨了交互式工具＂例子批判＂来帮助用户在大量选项中快速找到最合适的物品，并介绍了通过基于用户当前的喜好模型和潜在的隐藏喜好来计算建议来改善该技术的新技术。用合成和真实用户进行性能评估，结果表明，这些建议对用户非常吸引人，可以刺激他们表达更多的偏好以提高识别出最喜欢的物品的机会，提高了 78%。
