Abstract

This dataset is part of the data collection NGT-LEX-UvA-2025-video (https://doi.org/10.21942/uva.c.8723623).About the content of the data collectionThe NGT-LEX-UvA-2025-video data collection contains video recordings of lexical signs in Dutch Sign Language (NGT). Each sign has been recorded with five cameras, simultaneously, from different angles (M/L/R/A/B).Datasets with ‘nmm’ in their name contain video recordings of signs including non-manual markers (e.g. facial expressions and mouth movements). Datasets with ‘gloss’ in their name contain video recordings of signs that are purposely performed without non-manual markers, even though when used in context these signs would typically be performed with non-manual markers.The collection also contains three types of data derived from the original video data, namely MediaPipe pose estimation data, SAM 3D body keypoint estimation data and HaMeR handshape estimation data.See the NGT-LEX-UvA-2025-video_codebook dataset, which is part of this collection, for more details on the structure of the collection, file naming conventions, and a file mapping table.About the creation of the data collectionAll videos have been recorded at the SignLab video recording studio at the University of Amsterdam in 2023-2025. The data collection methods are described in detail in the following paper: https://aclanthology.org/2024.signlang-1.19/LicenseAll data is shared under a CC-BY 4.0 license.FundingThe creation of this data collection has been supported by the Platform Digital Infrastructure for the Social Sciences and the Humanities (PDI-SSH) in the Netherlands.AccessibilityThe video data is also accessible through the Global Signbank platform, where each video is associated with semantic and phonological information: https://signbank.cls.ru.nl/datasets/NGT/Related data collectionThe related data collection NGT-LEX-UvA-2025-animations (https://doi.org/10.21942/uva.c.8733523) provides 3D animations, created with motion capture equipment, for 1,736 lexical signs in the current data collection.About this datasetNGT-LEX-UvA-2025-video NGT sign gloss (lexical sign) recordings: raw (unprocessed) multi-camera videos (M/L/R/A/B) (part 29, in recording-date order).
