规划连贯的多句文本

虽然大多数文本生成器能够简单地将多个句子串在一起，但它们无法确定哪种顺序将确保一个连贯的段落。当连续句子中的信息遵循某种推理模式或听话人熟悉的知识模式时，一个段落是连贯的。为了表示这样的推论，说话者通常使用以固定方式连接连续句子的关系。Mann和Thompson的修辞结构理论提出了一组20种关系，涵盖了人们通常所说的大多数英语。本文介绍了这些关系的形式化和使用原型文本规划器，结构输入元素到连贯的段落。
Though most text generators are capable of simply stringing together more than one sentence, they cannot determine which order will ensure a coherent paragraph. A paragraph is coherent when the information in successive sentences follows some pattern of inference or of knowledge with which the hearer is familiar. To signal such inferences, speakers usually use relations that link successive sentences in fixed ways. A set of 20 relations that span most of what people usually say in English is proposed in the Rhetorical Structure Theory of Mann and Thompson. This paper describes the formalization of these relations and their use in a prototype text planner that structures input elements into coherent paragraphs.
