Morphological Rule Induction for Terminology Acquisition

Abstract

We present the identification in corpora of French relational adjectives (RAdj) such as gazeux (gaseous) which is derived from the noun gaz (gas). RAdj appearing in nominal phrases are interesting for terminology acquisition b ecause they hold a naming function. The derivational rules employed to compute the noun from which has been derived the RAdj are acquired semi-automatically from a tagged and a lemmatized corpora. These rules are then integrated into a termer which identifies RAdj thanks to their property of being paraphrasable by a prepositional phrase. RAdj and compound nouns which include a RAdj are then quantied, their linguistic precision is measured and their informative status is evaluated thanks to a thesaurus of the domain.
