引入了语义相关度计算是为了解决句法分析中的结构性歧义。

Semantic relevancy computation is used to solve structural disambiguity in parsing syntactic.

编译器层中包含了一些对象模型，这些模型与编译器管道的各个阶段暴露出来的信息——包括句法和语义上的信息——相关。

The compiler layer contains the object models that correspond with information exposed at each phase of the compiler pipeline, both syntactic and semantic.

当然，语法会带来一些限制；不过，对句法选项的选择的研究属于语义学、语用论和术语范畴。

Grammars provide some constraints here, of course; but the study of selection among syntactic options falls within the fields of semantics, pragmatics, and register.
