nlp - 斯坦福依存解析中的acl标签是什么？

Question

Stanford 依赖项解析中出现 acl 标记，手册中没有任何解释。例如，像“你要去那里吗”这样的句子，你会给出如下内容:

root(ROOT-0, are-1)
nsubj(are-1, you-2)
acl(you-2, going-3)     <--
advmod(going-3, there-4)

谁能解释一下这个标签是什么？

Answer 1

这是通用依赖关系表示中的新标签，记录如下: http://universaldependencies.github.io/docs/u/dep/acl.html

acl stands for finite and non-finite clauses that modify a nominal. The acl relation contrasts with the advcl relation, which is used for adverbial clauses that modify a predicate. The head of the acl relation is the noun that is modified, and the dependent is the head of the clause that modifies the noun.
