The Synt parser
The Synt is a tool for automatic syntactic analysis designed for morphologically-rich languages, primarily Czech and Slovak. Synt parser is based on a context-free backbone enhanced with contextual actions and performs a stochastic agenda-based head-driven chart analysis. The input for Synt parser is morphologically annotated sentence in vertical form. The output of Synt parser are: a phrase-structure tree, a dependency graph and a set of syntactic structures.

Synt grammar specification
The Synt parser uses a meta-grammar concept: to face maintenance and development issues of a wide-coverage grammar, a full grammar is automatically generated from a (hand-written) meta-grammar. Synt parser is based on a context-free backbone enhanced with contextual actions and performs a stochastic agenda-based head-driven chart analysis.

Synt input
The input for Synt parser is morphologically annotated sentence in vertical form or brief http://nlp.fi.muni.cz/trac/synt/wiki/input.
Synt output
See possible outputs here: https://nlp.fi.muni.cz/trac/synt/wiki/output
Usage
The input for Synt parser is a morphological annotated sentence either in vertical (word-per-line) or brief format (which allows ambiguous morphological input). Multiple sentences are separated by a blank line.
To provide basic syntactic analysis:
cat sentence.vert | synt -i vertical cat sentence.brief | synt -i brief
To provide syntactic analysis with phrase-structure tree output:
cat sentence.vert | synt -i vertical -tt-
