Arc

 

A convention used in relational grammar to represent a directional dependency relation between a syntactic unit (or governor) and the entities which constitute the relational structure of that unit. The “arcs” in a “relational network” are represented by curved arrows; alternatively, the dependency relations can be shown as a dependency tree. Arcs are also an important device in network grammars. Relationships can be postulated between pairs of arcs, and these pairs of arcs can then in turn be interrelated in “pair networks”.

 

关系语法的惯用术语,指一个句法单位(或支配语)与构成其关系结构的诸实体之间存在的一种有方向的依存关系。“关系网络”中的“弧”用曲线箭头表示;也可用依存关系树来表示依存关系。弧也是各种网络语法的一个重要手段。先在弧对与弧对之间假设各种关系,然后这些弧对再在“弧对网络”内互联。
