Dependency syntax analysis
Dependency Parsing (DP) reveals the syntactic structure of a language unit by analyzing the dependencies between components within it. Intuitively speaking, dependency syntactic analysis identifies the grammatical components of "subject, predicate, object" and "definitive complement" in the sentence, and analyzes the relationship between each component.
For the above example, the analysis result is:
• From the analysis results, we can see that the core predicate of the sentence is "proposed", the subject is "Li Keqiang", the object of proposed is "support Shanghai...", "when investigating..." is the (time) adverbial of "proposed", The modifier of "Li Keqiang" is "Prime Minister of the State Council", and the object of "support" is "exploring new mechanisms." With the above syntactic analysis results, we can easily see that the "proposer" is "Li Keqiang", not "Shanghai" or "Waigaoqiao", even though they are both nouns and are far away from "proposed" closer.
Dependency syntax analysis annotation relationships (14 types in total) and their meanings are as follows:
• Relationship type Tag Description Example
主谓关系 SBV subject-verb 我送她一束花 (我 <– 送)
动宾关系 VOB 直接宾语,verb-object 我送她一束花 (送 –> 花)
间宾关系 IOB 间接宾语,indirect-object 我送她一束花 (送 –> 她)
前置宾语 FOB 前置宾语,fronting-object 他什么乢都读 (乢 <– 读)
兼语 DBL double 他请我吃饭 (请 –> 我)
定中关系 ATT attribute 红苹果 (红 <– 苹果)
状中结构 ADV adverbial 非常美丽 (非常 <– 美丽)
动补结构 CMP complement 做完了作业 (做 –> 完)
并列关系 COO coordinate 大山和大海 (大山 –> 大海)
