== 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.

== Input ==
The input for Synt parser is morphologically annotated sentence in [vertical,http://nlp.fi.muni.cz/trac/synt/wiki/input] form or [brief,http://nlp.fi.muni.cz/trac/synt/wiki/input].

== 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.

                    Tlačil auto,

== 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-
}}}
