我们提出了一种基于同步依赖语法的简化文本方法。依赖性表示提供的较高水平的抽象允许对需要重新排序和形态学变化的复杂结构进行语言合理的处理，例如被动语音转换为主动。我们提出了一种同步的语法形式主义，其中很容易手工编写规则，并从一致的英语和简单的英语句子的依赖性解析中自动获取它们。语法形式主义是针对单语翻译进行了优化的，因为它可以在适当的情况下重用从源句子中订购信息。我们证明了我们的方法优于基于准同步树替代语法的领先当代系统，无论是在表达和性能方面。
We present an approach to text simplification based on synchronous dependency grammars. The higher level of abstraction afforded by dependency representations allows for a linguistically sound treatment of complex constructs requiring reordering and morphological change, such as conversion of passive voice to active. We present a synchronous grammar formalism in which it is easy to write rules by hand and also acquire them automatically from dependency parses of aligned English and Simple English sentences. The grammar formalism is optimised for monolingual translation in that it reuses ordering information from the source sentence where appropriate. We demonstrate the superiority of our approach over a leading contemporary system based on quasi-synchronous tree substitution grammars, both in terms of expressivity and performance.
