图像标注中的用户标注模式与心理研究

A Study of Annotation Patterns and User Psychology in Image Annotation

了解图像标注用户的行为模式与心理是建设与优化数字图书馆图像标注系统、提升图像用户体验的重要基础。本文通过实验采集用户使用三种图像标注方法的认知活动过程，经研究发现：①用户偏好可视化方法，且组合使用图像比较次序与滚动条方法的概率很高；②用户对精细化标注需求总体较小，且个体差异显著；③用户有10种典型图像标注模式，且图像比较次序方法对这些模式中的精细化标注极其重要；④用户在标注图像中存在定势效应与近因效应，且对参考图像模糊容忍度高。

Understanding user behavior patterns and psychologies in image annotation is an important basis of building and optimizing image annotation systems and improving user experiences in digital library. This study collected the cognitive activities and process while users annotated images with three existing methods in an experiment, and found that：①Users prefer the visualization methods, and the combination of image comparison method and scroll method has a very high frequency ;②The overall demand for detailing annotation is low, along with a significant individual difference;③There are ten typical annotation patterns, in which the image comparison method performs a vital role for detailing annotation ;④Observable user psychologies includes set effect, recency effect, and a high tolerance of ambiguity toward the reference image.
