A system demo presented at
Relating Grammatical Framework with Universal Dependencies
GF (Grammatical Framework) and UD (Universal Dependencies) are two different
approaches using shared syntactic descriptions for multiple languages. GF is a
categorial grammar approach using abstract syntax trees and hand-written
grammars, which define both generation and parsing. UD is a dependency approach
driven by annotated treebanks and statistical parsers. In closer study, the
grammatical descriptions in these two approaches have turned out to be very
similar, so that it is possible to map between them, to the benefit of both.
The demo presents a recent addition to the GF web demo, which enables the
construction and visualization of UD trees in 32 languages. The demo exploits
another new functionality, also usable as a command-line tool, which converts
dependency trees in the CoNLL format to high-resolution LaTeX and SVG graphics.
