nlp – 斯坦福依赖解析中的acl标记是什么？

一个acl标签出现在斯坦福依赖关系解析中,手册中没有解释.例如,像“你去那里”这样的句子,你给出了类似的东西：

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

有人能解释一下这个标签是什么吗？

这是Universal Dependencies表示中的新标签,在此处记录： 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.
