[Corpora-List] Morphological segmentation & Morphosemantic parsing for French

[Fiammetta NAMER]

Hi John and Edina,

I am currently developing a morpho-semantics parser for French (DériF)
based on linguistic constraints. Words decomposition is recursive,
hierarchical and any complex input (be it a neologism or an attested word)
is provided a pseudo-definition wrt to the morphological process which
relates it to its base.

Derif is developing one morphological process type (= module : for instance
noun-to-adjective -ique suffixation is a module) after the other, so that
it does not account for all morphological processes yet; so far,
it is able to parse around 30 word formation types, including suffixation,
prefixation rules, conversion and neoclassical compounding.

It is a simple Perl program, that requires only to have Perl 5.8 installed.

DeriF recent developments focus on biomedical terminology. Last DériF
version allows neoclassical compounds to be grouped into lexical classes,
by calculating  synonymy, hyponymy and approximation relations.

Here is an example:
===========================================
gastralgie/NOM==>
         [ [ gastr N* ] [ algie N* ]  NOM ]
(gastralgie/NOM, algie/N*)
" douleur (du -- liée au) estomac "

Constituants = /gastr/algie/

gastralgie/NOM: synonym of  gastrodynie/NOM,    stomacalgie/NOM,
stomacodynie/NOM,      stomachodynie/NOM, (gastralgique/ADJ)
gastralgie/NOM: subtype of  abdominalgie/NOM
gastralgie/NOM: see also  entéralgie/NOM,
         entérodynie/NOM, gastrite/NOM,
         hépatalgie/NOM, hépatodynie/NOM,
         pancréatalgie/NOM
=============================================

Unfortunately, it is still too soon to deliver a version of DeriF because
results have still to be validated.

As soon as results for medical terminology are validated (i.e. in a few
months, at the end of the French national UMLF project, coordinated by P.
Zweigenbaum and  supported by grants from the French Ministry of
Education), they will be made freely available for the scientific community

Greetings
