GeoQuery-LSFB: A French Belgian Sign Language Corpus with Procedural Semantic Annotations

Abstract 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 substantial 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.
