Syntactic Dependency

A Syntactic Dependency is a grammatical relation that establishes hierarchical connections between syntactic units based on structural relationships.

• AKA: Dependency Relation, Syntactic Relation, Grammatical Dependency, Structural Dependency.
• Context:
  • It can typically connect Head Words with dependent words in sentence structures.
  • It can typically express Grammatical Functions such as subject relations and object relations.
  • It can typically form Dependency Trees representing syntactic hierarchies.
  • It can typically capture Non-Local Dependencies between distant words.
  • It can typically support Syntactic Parsing through dependency grammars.
  • ...
  • It can often indicate Semantic Roles through syntactic positions.
  • It can often vary across Language Families with different word orders.
  • It can often determine Agreement Patterns for morphological features.
  • It can often constrain Word Movement in syntactic transformations.
  • ...
  • It can range from being a Local Syntactic Dependency to being a Long-Distance Syntactic Dependency, depending on its structural distance.
  • It can range from being a Obligatory Syntactic Dependency to being an Optional Syntactic Dependency, depending on its grammatical requirement.
  • It can range from being a Binary Syntactic Dependency to being a Complex Syntactic Dependency, depending on its relation complexity.
  • It can range from being a Universal Syntactic Dependency to being a Language-Specific Syntactic Dependency, depending on its cross-linguistic validity.
  • ...
  • It can integrate with Dependency Parsers for syntactic analysis.
  • It can connect to Semantic Parsers for meaning extraction.
  • It can interface with Machine Translation Systems for structure transfer.
  • It can communicate with Information Extraction Systems for relation extraction.
  • ...
• Example(s):
  • Subject-Verb Dependency connecting nominal subjects to verbal predicates.
  • Verb-Object Dependency linking transitive verbs to direct objects.
  • Modifier-Head Dependency attaching adjectives to nouns.
  • Specific Language Dependencies:
    • English Dependencies with SVO order
    • Japanese Dependencies with SOV order
    • Arabic Dependencies with VSO order
  • Prefix-Suffix Dependency in concept naming patterns.
  • ...
• Counter-Example(s):
  • Semantic Relation, which connects meanings rather than structures.
  • Morphological Relation, which links word forms rather than syntactic positions.
  • Linear Order, which reflects surface sequence without hierarchy.
