Change Log
- Fixed a few bugs, including missing id on anchor op.
- Completed to be able to take XML Derivation forests as input to forest_convert.pl
- Added input option to read XML DEP format (-f xmldep)
- Complete rewriting in order to be able to read XML DEP format.
- XML DEP format provides more information, in order to rebuild a shared derivation forest from a shared dependency forest. There are still some points to refine in relation with lexicals and epsilons (no target_op).
- Tried to fix autoconf wrt the use of strdupa. Maybe should try to avoid strdup !
- Added missing return info in deriv_signature functions
- Tried to fix algorithmic issues arising when dealing with large forests with a lot of duplicate ambiguities (spurious ambiguities).
- Slight modification of the formula for the ambiguity ratio
- Dependencies relative to a coanchor are now attached to the coanchor rather to the anchor of the tree.
- Updated verbose!anchor pattern for extra argument (used for hypertag)
