Existing grammars for other languages on the sameplatformExisting grammars for the same language on otherplatformsUniversal reusable grammar components
Hand-crafted grammarsLong development circleHigh linguistic precision can be achievedGrammar maintenance is difficult(Potentially) suitable for different tasks
Treebank-induced grammarsLarge annotated treebank is requiredSemi-automatic grammar adaptation and extensionMore suitable for parsing than generation
Highly consistent and powerful formalism (TFS)Monostratal, declarative, non-derivational, lexicalist,constraint-basedHas been studied for many different languagesPsycholinguistic evidence
