ASL SignBank

CLOSE glossesThe ASL SignBank is a tool being developed in relation to the SLAAASh Project in collaboration between researchers in our lab at UConn, and at Gallaudet University (Julie Hochgesang, lead). There is currently no one commonly-accepted orthography for American Sign Language. Additionally, the transcription systems used by different research groups are often inconsistent. The best practice is to base annotations on ID glosses. In an ID gloss system, exactly one word or phrase stands for exactly one sign. For this project, this means that for each ASL sign there is an English word that is used to label each sign consistently – regardless of meaning or of modification in context. Our laboratory has previously collaborated to create a database of conventions for ID glosses. The current focus is to improve, expand, and share this database.

ASLsignbank-screenshotThe ASL Signbank is not meant to be a dictionary, but rather a tool for researchers. It is currently under development and contains over 2000 signs. Researchers led by Onno Crasborn (Radboud University, Netherlands) are working to create a link between the ELAN program and the ASL SignBank. Changes or additions made to the online ASL SignBank will propagate through linked ELAN annotation files, making updates simple and straightforward for researchers to incorporate.
