定义有用的情感描述符来刻画表达行为是情感计算的一个重要研究领域。最近的研究表明，使用持续的情感评估来标注自发语料库是有好处的。这种方法不是为每个片段分配全局标签，而是捕捉情绪的时间动态演变。持续评估的一个挑战是评估者固有的反应滞后。在注释过程中，观察者需要感知刺激，感知情感信息，并定义他/她的判断，所有这些都是实时的。因此，我们预计注释和潜在的情感内容之间会有反应滞后。本文使用互信息来量化和补偿这种反应滞后。在语义数据库上的分类实验表明，在考虑评价者反应滞后的情况下，情感识别系统的性能有所提高。我们探讨了依赖于注释器和独立于注释器的补偿方案。
Defining useful emotional descriptors to characterize expressive behaviors is an important research area in affective computing. Recent studies have shown the benefits of using continuous emotional evaluations to annotate spontaneous corpora. Instead of assigning global labels per segments, this approach captures the temporal dynamic evolution of the emotions. A challenge of continuous assessments is the inherent reaction lag of the evaluators. During the annotation process, an observer needs to sense the stimulus, perceive the emotional message, and define his/her judgment, all this in real time. As a result, we expect a reaction lag between the annotation and the underlying emotional content. This paper uses mutual information to quantify and compensate for this reaction lag. Classification experiments on the SEMAINE database demonstrate that the performance of emotion recognition systems improve when the evaluator reaction lag is considered. We explore annotator-dependent and annotator-independent compensation schemes.
