SLs are complex visio-gestural communication systems; by using corporal gestures, signers achieve the same level of expressivity held by sound-based languages like English or French.

Have you forgotten your login? With the PDLSL, body articulators like the hands or head are interpreted as independent agents; each oropositionnelle has its own set of valid actions and propositions, and executes them without influence from the others.

A multi-modal logic was chosen as the basis of the formal language: The final product, is an automatically generated sub-lexical annotation, which can be later corrected by human annotators for their use in other areas propositiobnelle as linguistics.

Together, the use of PDLSL and the proposed specialized data structures could help curb some of the current problems in SL study; notably the heterogeneity of corpora and the lack of automatic annotation aids. For this reason, the current work presents the development of a formal representation framework, intended to transform SL video repositories corpus into an intermediate representation layer, where automatic recognition algorithms can work under better conditions. Friday, October 26, – 4: This situation, paired with an extensive use of the three-dimensional space, make them difficult to represent with tools already existent in Natural Language Processing NLP of vocal languages.

The simultaneous execution of different actions by several articulators yield distinct situations, which can be searched over an LTS with formulae, by using the semantic rules of the logic.

With this, annotations is possible by defining with formulae the characteristics to annotate. However, unlike these, SL morphemes correspond to complex sequences of highly specific body postures, interleaved with postural changes: Using formal logic to represent sign language phonetics in semi-automatic annotation tasks.

In particular, PDL uses the modal operators [a] and to denote necessity and possibility, respectively. Les LS sont de langues naturelles, qui utilisent des gestes et l’espace autour du signeur pour transmettre de l’information. This thesis presents a formal framework for the representation of Signed Languages SLsthe languages of Deaf communities, in semi-automatic recognition tasks.

Pogique, the development of the formal framework led to the creation of a semi-automatic annotator based on the presented theoretical principles. Monday, Propositionnells 20, – Document and Text Processing.

The main idea is that corpora can be described with a specialized Labeled Transition System LTSwhich can then be annotated with logic formulae for its study.

Traitement automatique du langage naturel Annotation automatique Langue des signes Logique propositionnelle dynamique. This logic was originally created to specify and prove properties on computer programs.

For SLs, a particular variant based on the original formalism was developed: On the same vein, this may rpopositionnelle only increase the size propositoonnelle the available datasets, but even extend previous results to new corpora; the framework inserts an intermediate representation layer which can serve to model any corpus, regardless of its technical limitations.

Afterwards, a formal verification algorithm may be able to find those features in corpora, as long as they are represented as consistent LTSs. De ce fait, un chercheur peut rendre exploitables des corpus existants en les transformant vers des STE.
