Procedural semantic representations describe the meaning of natural language expressions in terms of computer programs that can be evaluated against images, databases, knowledge graphs or other external resources. While resources annotated with procedural semantic representations already exist for a variety of spoken languages, such resources are still lacking entirely for signed languages. In this paper, we introduce GeoQuery-LSFB as a signed language extension to the multilingual GeoQuery corpus. Concretely, we have complemented each procedural semantic annotation from the original corpus with a corresponding French Belgian Sign Language (LSFB) expression that was phonetically transcribed from video recordings following the HamNoSys convention and annotated with French ID-glosses. The GeoQuery-LSFB corpus constitutes a new resource for a low-resource language and offers for the first time the possibility to study, from an onomasialogical perspective, a signed language along a diverse variety of spoken languages.

The overarching objective underlying this research is to develop an online tool, based on a parallel corpus of French Belgian Sign Language (LSFB) and written Belgian French. This tool is aimed to assist various set of tasks related to the comparison of LSFB and French, to the benefit of general users as well as teachers in bilingual schools, translators and interpreters, as well as linguists. These tasks include (1) the comprehension of LSFB or French texts, (2) the production of LSFB or French texts, (3) the translation between LSFB and French in both directions and (4) the contrastive analysis of these languages. The first step of investigation aims at creating an unidirectional French-LSFB concordancer, able to align a one- or multiple-word expression from the French translated text with its corresponding expressions in the videotaped LSFB productions. We aim at testing the efficiency of this concordancer for the extraction of a dictionary of meanings in context. In this paper, we will present the modelling of the different data sources at our disposal and specifically the way they interact with one another.
