Building factorized TAGs with meta-grammars

International audienceHighly compacted TAGs may be built by allowing subtree factorization operators within the elementary trees. While hand-crafting such trees remains possible, a better option arises from a coupling with meta-grammar descriptions. The approach has been validated by the development of FRMG, a wide-coverage French TAG of only 207 trees

Intégration des données d'un lexique syntaxique dans un analyseur syntaxique probabiliste

ISBN : 978-2-7453-2512-9International audienceThis article reports the evaluation of the integration of data from a syntactic-semantic lexicon, the Lexicon-Grammar of French, into a syntactic parser. We show that by changing the set of labels for verbs and predicational nouns, we can improve the performance on French of a non-lexicalized probabilistic parser

Convertir des dérivations TAG en dépendances

International audienceLes structures de dépendances syntaxiques sont importantes et bien adaptées comme point de départ de diverses applications. Dans le cadre de l'analyseur TAG FRMG, nous présentons les détails d'un processus de conversion de forêts partagées de dérivations en forêts partagées de dépendances. Des éléments d'information sont fournis sur un algorithme de désambiguisation sur ces forêts de dépendances

Towards an environment for the production and the validation of lexical semantic resources

International audienceWe present the components of a processing chain for the creation, visualization, and validation of lexical resources (formed of terms and relations between terms). The core of the chain is a component for building lexical networks relying on Harris' distributional hypothesis applied on the syntactic dependencies produced by the French parser FRMG on large corpora. Another important aspect concerns the use of an online interface for the visualization and collaborative validation of the resulting resources

Encoding a syntactic dictionary into a super granular unification grammar

International audienceWe show how to turn a large-scale syntactic dictionary into a dependency-based unification grammar where each piece of lexical information calls a separate rule, yielding a super granular grammar. Subcategorization, raising and control verbs, auxiliaries and copula, passivization, and tough-movement are discussed. We focus on the semantics-syntax interface and offer a new perspective on syntactic structure

Challenges of language change and variation: towards an extended treebank of Medieval French

International audienceIn order to automatically extend a treebank of Old French (9 th-13 th c.) with new texts in Old and Middle French (14 th-15 th c.), we need to adapt tools for syntactic annotation. However, these stages of French are subjected to great variation, and parsing historical texts remains an issue. We chose to adapt a symbolic system, the French Metagrammar (FRMG), and develop a lexicon comparable to the Lefff lexicon for Old and Middle French. The final goal of our project is to model the evolution of language through the whole period of Medieval French (9 th-15 th c.)
