The Data Access Interface (DAI) <http://secrets.rutgers.edu/dai/queryPages/> allows browsing, search, and download of ASL video data (linguistically annotated through use of SignStream®), for (a) the National Center for Sign Language and Gesture Resources (NCSLGR) corpus; and (b) ~10,000 examples (almost 3,000 distinct signs) in citation form, as part of the American Sign Language Lexicon Video Dataset (ASLLVD), which forms the basis for the initial ASLLRP Sign Bank (see above).

A new Beta version of our Data Access Interface, DAI 2, to faciliate, browsing, search, and download of data from our expanding corpora, annotated through use of SignStream® 3 (with more detailed morpho-phonological information than in previous datasets) is now available! For details, see http://www.bu.edu/asllrp/about-dai2.html. This interface currently allows access to 12 collections from our new ASLLRP SignStream® 3 Corpus, with a total of over 400 utterances from 2 different signers (just over 2,600 signed examples corresponding to just over 600 distinct sign/variants). Additional data from this corpus will be released in the next few months, as soon as verifications are complete. Here is an illustration of search results for (1) the sign glossed as "ALWAYS" (on top), and (2) negation (partial) in DAI 2:
