"dependency grammar" の定義と意味

What is "dependency grammar"?

Dependency grammar is a linguistic framework that describes sentence structure in terms of relationships between words, focusing on how words depend on one another. In this approach, each word is connected to a "head" word, forming a tree-like structure where each word has a specific grammatical role based on its relationship to other words. Dependency grammar emphasizes the importance of these connections over traditional phrase structure rules, allowing for a more flexible representation of syntactic relationships. This framework is particularly useful for analyzing languages with free word order and for understanding how meaning is conveyed through the interplay of dependent words in a sentence.
