The Sign Language Dataset Compendium


LESCO Corpus

The LESCO Corpus is a collection of videos of Costa Rican Sign Language signers. Of a total of 196 filming sessions, producing 34 hours of recording and involving 141 signers 44 films showing 27 signers and totalling in 2 hours of recodring were selected for the corpus.

The corpus was produced between 2010 and 2013 in a project led by Alejandro Oviedo and Christian Ramírez Valerio.

The signers are filmed in a dialogic situation with a Deaf researcher present. Filming was done with two to three cameras, filming each participant and – for some filming – a close-up of the informants face. The data contains elicitation with a structured interview based on a questionaire, unstructured dialogue between informant and a Deaf researcher, unstructured dialogue between two informants, narration of a cartoon short film and free narration about personal anecdotes.

On basis of the LESCO Corpus the Dictionary of LESCO and a grammar of LESCO are created.
