• Tradeoffs in the Efficient Detection of Sign Language Content in Video Sharing Sites

  Caio D. D. Monteiro, Frank M. Shipman, Satyakiran Duggina, Ricardo Gutierrez-Osuna · 2019 · ACM Transactions on Accessible Computing (TACCESS)

  This paper addresses the problem of finding sign language (SL) content on video sharing sites like YouTube, where such videos serve as de-facto digital libraries of Deaf community knowledge, experiences, and culture. Metadata-based search is inadequate — prior work showed only…
