最佳-最差尺度是一种判断格式,参与者面前有K个项目,他们必须从这些项目中选择最好和最差的项目,以及一些潜在的维度。最近在自然语言处理和心理学中使用最佳-最差缩放法来收集词汇语义规范。在这种申请中,每次试验总是提出四个项目。目前的研究提供了一个推理,即除4之外的值可能提供更好的潜在值估计。模拟实验和行为研究的结果证实了这一点:两者都表明,在一般情况下,每次试验六个项目可以更好地减少潜在价值估计的误差。
Best–worst scaling is a judgment format in which participants are presented with K items and must choose the best and worst items from that set, along some underlying latent dimension. Best–worst scaling has seen recent use in natural-language processing and psychology to collect lexical semantic norms. In such applications, four items have always been presented on each trial. The present study provides reasoning that values other than 4 might provide better estimates of latent values. The results from simulation experiments and behavioral research confirmed this: Both suggest that, in the general case, six items per trial better reduces errors in the latent value estimates.
