Universal Dependencies
https://universaldependencies.org/ Universal Dependencies (UD) is a framework for consistent annotation of grammar (parts of speech, morphological features, and syntactic dependencies) across different human languages. UD是一个为了对不同人类语言的语法(词性、词法特性、句法依赖)进行连续标记的框架。 Morphology The morphological specification of a (syntactic) word in the UD scheme consists of three levels of representation: A lemma representing the semantic content of the word. A part-of-speech tag representing the abstract lexical category associated with the word. A set of features representing lexical and grammatical properties that are associated with the particular word form.
