What constraints for representing multilinearity in Sign language?

International audienceIn this paper, we present our current investigations on one of the main challenges in Sign Language modelling: multilinearity. We explain the way in which we extract grammatical rules from Sign Language corpus, and how we represent them with constraints. Two kinds are needed: time synchronisation and geometric constraints

Modeling French Sign Language: a proposal for a semantically compositional system

International audienceThe recognition of French Sign Language (LSF) as a natural language in 2005 created an important need for the development of tools to make information accessible to the deaf public. With this prospect, the goal of this article is to propose a linguistic approach aimed at modeling the French sign language. We first present the models proposed in computer science to formalize the sign language (SL). We also show the difficulty of applying the grammars originally designed for spoken languages to model SL. In a second step, we propose an approach allowing to take into account the linguistic properties of the SL while respecting the constraints of a modelisation process. By studying the links between semantic functions and their observed forms in Corpus, we have identified several production rules that govern the functioning of the LSF. We finally present the rule functioning as a system capable of modeling an entire utterance in French sign language

Corpus de langue des signes : situer les biais des méthodes d’annotation et d’analyse

Cet article propose un tour d’horizon de différents types de biais que l’on peut rencontrer dans les études basées sur l’annotation de corpus vidéo de langue des signes. En tâchant de situer objectivement les choix effectués et les biais potentiels à chaque étape, nous décrivons les méthodologies que nous avons mises en place dans trois études, portant respectivement sur la synchronisation des composantes corporelles, le mouvement des sourcils et les clignements des yeux, puis la coarticulation.This article offers an overview of different types of bias that may be encountered in studies based on video corpus annotation of sign language. We describe the methods we have implemented and we try to objectively exhibit the choices made and the potential biases for each step, in three studies, on synchronization of body components, on eyebrow movement and eye blink, and on coarticulation
