From a ltag grammars and input automaton, it generates a derivation forest as an unification grammar in two ways :
one which is overgenerating (extraction in O(n^3))

the other which is sound (extraction in O(n^6) but which has some drawbacks : in order to avoid the problem of non termination on some rules [see Shieber's restriction on [Shieber et al, 92], it has to be ran under a tabular logic programming environment and the stack of adjunction has to be evaluated bottom-up.

So first using swi-prolog, one has to generate the forest, which has then to be interpreted with DyALog. I included some kind of a very light loop detection emulator using a deept-n recognizer.

*The unifications are precompiled into the trees and the calculus of the features unification are done during the walk of the forest (usually, people generates the derivation trees and then extract the derived tree and apply the unification on the nodes then), so far I included a basic treatment of a few features into this scheme

*if a lexical entry has a control canvas information (control verb), the programs generates a dependency graph.

I'm working on including the treatmnent of coordination as in [seddah et sagot,2006] .

Don't be disapointed, it's far from being usable in a production environment, it's first a proof of concept, then a parser. The grammar format follow the DyALog tree description.

This version is dated from March 2004, I have to grab the last one from my old lab server.
