Update on linguistically annotated ASL video data available through the American Sign Language Linguistic Research Project (ASLLRP)

Abstract

The American Sign Language Linguistic Research Project (ASLLRP) provides Internet access to high-quality ASL video data, generally including front and side views and a close-up of the face. The manual and non-manual components of the signing have been linguistically annotated using SignStream®. The recently expanded video corpora can be browsed and searched through the Data Access Interface (DAI 2) we have designed; it is possible to carry out complex searches. The data from our corpora can also be downloaded; annotations are available in an XML export format. We have also developed the ASLLRP Sign Bank, which contains almost 6,000 sign entries with distinct English-based glosses, with a total of 41,830 examples (in addition to about 300 gestures, over 1,000 fingerspelled signs, and 475 classifier examples). The Sign Bank is likewise accessible and searchable on the Internet; it can also be accessed from within SignStream® to make annotations more accurate and efficient. Here we describe the available resources. These data have been used for many types of research into computerbased sign language recognition from video.
