Sign language resources

Introduction

This CLARIN Resource family page lists corpora and lexica for Sign Languages (SL). A substantial number of these can be found in the CLARIN but deserve a special podium in the spotlight. 

Sign language (SL) corpus resources contain transcriptions/annotations of spontaneous or elicited dialogues and narratives. All resources are in a video format because of the gestural/spatial-visual modality, a vital characteristic of signed languages (sign languages, used by Deaf-blind signers, can be received in tactile modality). SL corpora are crucial resources for various types of linguistic research, such as lexicography, phonology, syntax, and pragmatics, as well as for language typology. 

This page also provides access to SL lexical resources. Some of them are connected to SL corpora. There also are independent lexical resources that were primarily created for language learning and teaching.

This page was constructed by harvesting metadata for SL corpora in three different ways:

  • By making an inventory of the material (datasets and resources) offered by CLARIN K-Centres with expertise in SL.
  • By making an inventory of other datasets in the VLO which may qualify as members of the new CRF by contacting the right holders.
  • By making an inventory of any other material (e.g., new datasets, annotation tools, manuals) not yet accessible through the CLARIN Infrastructure by sending out questionnaires to SL communities.

For comments, changes of the existing content or inclusion of new corpora, send us an email.

Sign-Hub WP2.4: Life Stories

Size: 200 hours

Annotation: not annotated yet

Licence: CLARIN PUB

Catalan Sign Language (LSC), German Sign Language (DGS), Italian Sign Language (LIS), Dutch Sign Language (NGT), Spanish Sign Language (LSE), and Turkish Sign Language (TİD).

This is a collection of datasets connected to the Sign-Hub project. The corpus contains interviews conducted with elderly Deaf signers from five countries on their life experiences as well as a documentary movie based on these interviews. These interviews were conducted in five of the participating countries of the SIGN-HUB project and in six different sign languages: Catalan Sign Language (LSC), German Sign Language (DGS), Italian Sign Language (LIS), Sign Language of the Netherlands (NGT), Spanish Sign Language (LSE), and Turkish Sign Language (TİD). In each country, interviews have been conducted in different geographical areas. The exact number of interviews differs per sign language, but for every sign language, at least 20 interviews have been conducted, with interviewees being between 66 and 97 years of age. Interviews followed a pre-defined questionnaire; however, the addition of country-specific questions was encouraged.

This collection is available for download from the Ortolang repository.

Dogon Sign Language

The Dogon Sign Language Corpus contains 32 hours of video data, recorded in the Dogon area in Mali between 2010 and 2012. These recordings are cut into 341 shorter clips varying lengths, in MPG1 and MPG2 format. The recordings feature the signing of 41 men and 27 women. The average age of all signers was 30 years.

  • personal narratives
  • interviews about personal history
  • signed guided tours by deaf signers around the house, fields and nature
  • elicited lexical data
  • reports by the team members of the data collection

Metadata are stored in the sign language format, using the ARBIL editor software. The entire corpus, i.e. the video clips, annotations and metadata, is stored in the DoBeS archive at the Max Planck Institute for Psycholinguistics in Nijmegen.

Each dyad is composed of a speaker located on the right of the overview noted A, and a moderator located on the left of the overview noted B. Thus, for session 1, the speakers are conversing in French, A1 is the speaker located on the right of the overview and B1 is the moderator located on the left of the overview. For each session there are 4 video files (mp4/AVC): 1 for the speaker, 1 for the moderator, 1 which gives a profile view of the two speakers, the overview, and 1 which is a montage of these 3 videos. All the files are synchronised. For the LSF part, there is no sound track in the videos. For the French part, there are 2 sound files (wave) in addition to the video files, 1 per speaker. The first 3 videos do not contain a sound track. Only the editing video contains sound, that of the speaker on the right in the right channel and that of the moderator on the left in the left channel.

This is an amateur sign-language database comprising 25 signs from Czech sign language. 15 signers (4 women and 11 men) carried out 5 repetitions of each sign and were recorded from 3 different views. The first is a frontal view of the upper part of the body. The second one is similar, but with the camera placed about one meter higher than the first one so as to produce a frontal top-view, and thus allowing to detect 3D information. The last view is a frontal-detail view of the speaker's face, thus allowing lip-reading.

CORLSE

Size: 4 hours 52 minutes / 48 recordings

Annotation: partly annotated

Spanish Sign Language (LSE)

This corpus is intended for the analysis of LSE argument structure, focusing on how signers organize the names (and the forms similar to the names) and the verbs (and other forms that have a predicative function) to communicate who does what, or feels what, or talks about what, etc. It was not intended to create a representative and structured corpus, but rather a set of examples that would allow basing the grammatical description on contextualized uses. Only a part is accessible through the iSignos website. The corpus is annotated as follows: there are right-hand and left-hand id-glosses and glosses for classifiers, translation into Spanish and role-shift, PoS, argument structure, locus and animacy (2 hours and 21 minutes). Other part just with glosses, translation into Spanish and role-shift; some recordings (16) also have analysis of the non-manual component

iSignos

Annotation: annotated for right-hand and left-hand id-glosses and glosses for classifiers and Spanish translations

Spanish Sign Language (LSE)

This corpus consists of a set of video recordings of signers who express themselves in LSE, presented together with the glosses of both hands and the Spanish translation. In the first stage, a set of videos with their corresponding glosses and translations are available, which will be expanded in successive phases. You can consult the list of recordings and select by genre or theme criteria, and also by the sex or age range of the signers.The resource can be useful for all those people who need this type of linguistic data for their work, for example, for class exercises, interpretation practices, language evaluations, research on LSE, etc.

The corpus is available through a dedicated sarch engine that allows you to explore the corpus and observe the context in which the searched glosses appear.

Czech Sign Language Corpus for Recognition – Amateur Signer

Licence: ELRA

Czech Sign Language

This is an amateur sign-language database comprising 25 signs from Czech sign language. 15 signers (4 women and 11 men) carried out 5 repetitions of each sign and were recorded from 3 different views. The first is a frontal view of the upper part of the body. The second one is similar, but with the camera placed about one meter higher than the first one so as to produce a frontal top-view, and thus allowing to detect 3D information. The last view is a frontal-detail view of the speaker's face, thus allowing lip-reading.
