论文摘要
已经进行了几项尝试在构建抽象含义表示形式（AMRS）组合上，最近简化了与HR-Algebra一起使用s Gaphs的想法（Koller，2015年），以减少解析时的选项数量（Groschwitz等人，2017年）。此应用模式定位代数（AM-Algebra）是具有两种操作的语言合理的图形代数，两种操作是第二等级：应用程序的申请操作用于将谓词与其参数相结合；修改操作用于修改谓词。虽然AM-Elgebra正确处理相对条款和复杂的协调案例，但它不能解析反思性句子，例如：“乌鸦自洗手”。为了促进这种反身句子的处理，本文提议更改AM-Elgebra基础的S图的定义，以允许具有多个来源的顶点，并提出对代数系统的适应性，以正确处理此类顶点。
Several attempts have been made at constructing Abstract Meaning Representations (AMRs) compositionally, and recently the idea of using s-graphs with the HR-algebra (Koller, 2015) has been simplified to reduce the number of options when parsing (Groschwitz et al., 2017). This apply-modify algebra (AM-algebra) is a linguistically plausible graph algebra with two classes of operations, both of rank two: the apply operation is used to combine a predicate with its argument; the modify operation is used to modify a predicate. While the AM-algebra correctly handles relative clauses and complex cases of coordination, it cannot parse reflexive sentences like: "The raven washes herself." To facilitate processing of such reflexive sentences, this paper proposes to change the definition of s-graphs underlying the AM-algebra to allow vertices with multiple sources, and additionally proposes an adaption to the type system of the algebra to correctly handle such vertices.
