Credits for Data Collection and Annotation
The National Center for Sign Language and Gesture Resources (NCSLGR) corpus available from this Web site was collected at Boston University under the supervision of Carol Neidle (for linguistic aspects of the data collection and annotation of the data) Stan Sclaroff (for computer science aspects of data collection, especially issues related to cameras and video files)
- The linguistic data collection, analysis, and annotation were carried out thanks to important contributions of the following people:
Carol Neidle, Robert G. Lee, Dawn MacLaughlin, Joan Nash, Quinn Duffy, Benjamin Bahan, Michael Schlang, Fran Conlin, Sarah Fish, Donna Riggle, Jessica Scott, Tory Sampson, Carla DaSilva, Lana Cook, Ginger Leon, Norma Bowers Tourangeau, Barbara Eger, Katherine Feldmann, Erica Hruby, Judith Labath, Deborah Perry, John Pirone, Tamara Rae Neuberger, Jon Suen, Jaimee DiMarco, Braden Painter.
The annotation conventions are documented in reports 11 and 13 linked to this page: http://www.bu.edu/asllrp/reports.html
- Thanks also to the following people for invaluable technical assistance with video data collection and computer vision analysis:
Stan Sclaroff, Vassilis Athitsos, Ashwin Thangali, Gary Wong, Margrit Betke, Joni Alon, Murat Erdem, Quan Yuan.
- Development of SignStream® has involved contributions from the following people:
Carol Neidle, Otmar Foelsche, David Greenfield (principal programmer for SignStream® through version 2.2.2), Dawn MacLaughlin, Robert G. Lee, Iryna Zhuravlova (principal programmer for SignStream® version 3, currently under development), Joan Nash, Ben Bahan, Jason Boyd, Stan Sclaroff, John Olson, Jack Hoza, George Kierstein, Judy Kegl, Patricia Trowbridge.
The SignStream® annotations are available through the DAI as XML files.
- Development of the Data Access Interface (DAI) was begun by Ben Waber and continued by Eugene Khafizov (with some contributions from Phil Nichols and Steven Li). A majorreimplementation was carried outin 2010-11 by Christian Vogler. Ongoing development is being carried out by Christian Vogler (as project manager), who was assisted by Richard Goodrow during parts of 2011 and 2012, in collaboration with Carol Neidle and the rest of the research team.
