Evaluating and improving syntactic lexica by plugging them within a parser

Proceedings of the Eighth International Conference on Language Resources and Evaluation (LREC'12)

We present some evaluation results for four French syntactic lexica, obtained through their conversion to the Alexina format used by the Lefff lexicon, and their integration within the large-coverage TAG-based FRMG parser. The evaluations are run on two test corpora, annotated with two distinct annotation formats, namely EASy/Passage chunks and relations and CoNLL dependencies. The information provided by the evaluation results provide valuable feedback about the four lexica. Moreover, when coupled with error mining techniques, they allow us to identify how these lexica might be improved.

Extending the adverbial coverage of a French morphological lexicon

Proceedings of the Eighth International Conference on Language Resources and Evaluation (LREC'12)

We present an extension of the adverbial entries of the French morphological lexicon DELA (Dictionnaires Electroniques du LADL / LADL electronic dictionaries). Adverbs were extracted from LGLex, a NLP-oriented syntactic resource for French, which in its turn contains all adverbs extracted from the Lexicon-Grammar tables of both simple adverbs ending in -ment (i.e., '-ly') and compound adverbs. This work exploits fine-grained linguistic information provided in existing resources. The resulting resource is reviewed in order to delete duplicates and is freely available under the LGPL-LR license.

Intégrer les tables du Lexique-Grammaire à un analyseur syntaxique robuste à grande échelle

Actes de la 16ème conférence sur le Traitement Automatique des Langues Naturelles. Articles courts

Dans cet article, nous montrons comment nous avons converti les tables du Lexique-Grammaire en un format TAL, celui du lexique Lefff, permettant ainsi son intégration dans l’analyseur syntaxique FRMG. Nous présentons les fondements linguistiques de ce processus de conversion et le lexique obtenu. Nous validons le lexique obtenu en évaluant l’analyseur syntaxique FRMG sur le corpus de référence de la campagne EASy selon qu’il utilise les entrées verbales du Lefff ou celles des tables des verbes du Lexique-Grammaire ainsi converties.
