Update on linguistically annotated ASL video data available through the American Sign Language Linguistic Research Project (ASLLRP)
Neidle, Carol; Opoku, Augustine
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.
