Catalan Sign Language Corpus

The Catalan Sign Language Corpus (LSC CORPUS) is an annotated corpus of LSCCatalan Sign Language. Recordings were made in twelve deaf clubs around Catalonia. The participants were recorded in pairs, sitting opposite each other in front of a blue background. The signing is captured in a frontal perspective using two HD cameras. A Deaf signer led the participants through the recordings.

The corpus project started in late 2012 with a two-year pilot phase (Barberà et al., 2015) which then led to a long-term project that is still ongoing. The first public version of the corpus was released in 2025. The annotations of the LSC Corpus are associated with a lexical database (Quer Villanueva, 2017). A diverse set of data collection tasks was used to collect different discourse genres. Some of the tasks were adopted from the DGS Corpus, Corpus NGT , British Sign Language Corpus and Auslan Corpus .The corpus was created at the Institute for Catalan Studies, led by Josep Quer Villanueva and Gemma Barberà Altimira.
