= DELPH-IN converter to bilexical dependencies =

== Background ==

The script converts ERG derivation tree to bi-lexical syntactic dependencies (dubbed DT), and ERG [[http://moin.delph-in.net/EdsTop|Elementary Dependency Structures]] to bi-lexical semantic dependencies (dubbed DM).

See brief [[http://www.delph-in.net/2013/tools.pdf|presentation of new DELPH-IN Tools]] from the 9th DELPH-IN Summit 31 July 2013.

== Installation ==

The converter script is located in the [[http://moin.delph-in.net/LogonTop|LOGON Source Tree]] (see [[http://moin.delph-in.net/LogonInstallation|LogonIstallation]] about the installation of LOGON tree on your machine):

${LOGONROOT}/uio/dtm/converter.py

A brief documentation is available at ${LOGONROOT}/uio/dtm/converter.pdf

== Usage ==

$LOGONROOT/bin/dtm  is the wrapper that invokes the converter:

$LOGONROOT/bin/dtm --grammar /usit/abel/u1/angelii/logon/lingo/erg --data <data> --tok erg --dtm <output> --tex <output>$LOGONROOT/bin/dtm --grammar /usit/abel/u1/angelii/logon/lingo/erg --data <data> --tok erg --dtm <output> --tex <output>
