在两个口语对话语料库上考察了熵率不变性对对话的适用性。这一原则被发现是成立的；然而，在对话的主题片段中描述了不同于书面文本的新的熵变化模式。说话人作为话题发起者和话题响应者的动态角色分别与递减和递增的熵相关，这导致了这些说话人在每个话题集中的局部收敛。这意味着对话中的句子熵取决于说话人角色所决定的不同语境。从扎根理论和互动对齐的角度对对话进行了解释，形成了一种新颖的、统一的信息论对话方法。
The applicability of entropy rate constancy to dialogue is examined on two spoken dialogue corpora. The principle is found to hold; however, new entropy change patterns within the topic episodes of dialogue are described, which are different from written text. Speaker’s dynamic roles as topic initiators and topic responders are associated with decreasing and increasing entropy, respectively, which results in lo-cal convergence between these speakers in each topic episode. This implies that the sentence entropy in dialogue is conditioned on different contexts determined by the speaker’s roles. Explanations from the perspectives of grounding theory and interactive alignment are discussed, resulting in a novel, unified information-theoretic approach of dialogue.
