Editing Dependency grammar (section)

==Dependency grammars==
The following frameworks are dependency-based:

* [[Algebraic syntax]]
* [[Operator grammar]]
* [[Link grammar]]
* [[Functional generative description]]
* [[Lexicase]]
* [[Meaning–text theory]]
* [[Word grammar]]
* [http://www.ps.uni-saarland.de/~rade/xdg.html Extensible dependency grammar]
* [[Universal Dependencies]]

[[Link grammar]] is similar to dependency grammar, but link grammar does not include directionality between the linked words, and thus does not describe head-dependent relationships. Hybrid dependency/phrase structure grammar uses dependencies between words, but also includes dependencies between phrasal nodes – see for example the [[Quranic Arabic Corpus|Quranic Arabic Dependency Treebank]]. The derivation trees of [[tree-adjoining grammar]] are dependency structures, although the full trees of TAG rendered in terms of phrase structure, so in this regard, it is not clear whether TAG should be viewed more as a dependency or phrase structure grammar.

There are major differences between the grammars just listed. In this regard, the dependency relation is compatible with other major tenets of theories of grammar. Thus like phrase structure grammars, dependency grammars can be mono- or multistratal, representational or derivational, construction- or rule-based.
