SLAAASh Project

slaash-logo
This project is being conducted jointly between researchers at Gallaudet University (Deborah Chen Pichler, Julie Hochgesang, and others) and the University of Connecticut. SLAAASh is short for “Sign Language Acquisition, Annotation, Archiving and Sharing” though sometimes we instead use “SLAASh” to refer to our overall goal to “annotate, archive, and share” sign language video data from all ages.

Language data usually needs to be transcribed in order to be machine-readable and usable for research. This is especially true for sign language data collected on videotape. Large corpora are available for many other languages, shared between different labs and projects for research use. Yet, no large and shared corpus exists for ASL. Our goal is to prepare a corpus of previously collected data on ASL acquisition to share with other researchers, in order to permit more researchers to conduct studies relating to ASL acquisition and use.

 

Video-still-MOTJILThe video data to be used consists of Child ASL data from the CLESS project previously conducted by our lab. Because the data was originally collected for another purpose, one of our initial goals is to request consent for further data sharing from all past participants and seek ethically-sound, community-supported practices for decision making. Our lab has held focus groups for input from various types of stakeholders: Potential participants, family members, and other Deaf community members. Our primary concern is protection of individual rights, with research as an important but secondary concern.

ELAN-tiersPrevious annotation of the ASL video data needs standardization in order to be usable by a wider shared audience. The ASL SignBank’s lexicon of ID glosses will facilitate this. (See project page for more information.)

 

Our current day-to-day focus is on converting old annotation files to the new system, completing annotation of previously unfinished files, and conducting basic analyses of the data, including vocabulary counts, MLU, and IPSyn analyses. We plan to release each data set as it is prepared and to share our tools such as the ASL SignBank open source.
