ISO 24615-1:2014描述了句法注释框架（SynAF），这是一种表示语言数据句法注释的高级模型，旨在支持跨语言资源或语言处理组件的互操作性。ISO 24615-1:2014是对ISO 24611（MAF，形态句法注释框架）的补充，并与之密切相关，它为句法表示和参考数据类别提供了一个元模型，用于表示句子或其他类似话语和片段中的成分和依赖信息。

ISO 24615-1:2014 describes the syntactic annotation framework (SynAF), a high level model for representing the syntactic annotation of linguistic data, with the objective of supporting interoperability across language resources or language processing components. ISO 24615-1:2014 is complementary and closely related to ISO 24611 (MAF, morpho-syntactic annotation framework) and provides a metamodel for syntactic representations as well as reference data categories for representing both constituency and dependency information in sentences or other comparable utterances and segments.
