Corpora
CRL has a number of natural language corpora that are available to members of the Center. Some of these corpora are accessible on-line; other corpora exist on CD-ROM, so special arrangements must be made to use them. Because most of the corpora are proprietary and have usage restrictions, access is only available to researchers affiliated with CRL.
NEW: A Linux-port of the Penn Treebank search utility tgrep is now available from CRL.

Announcements |

 Children with Language Learning Disabilities have difficulty learning and using language despite having normal intelligence. These learning deficits often cause frustration and/or failure in academic and peer-social settings.
To learn more about our study or to find out if your child is eligible to participate, please contact Child Language & Cognitive Processes Lab at palm@crl.ucsd.edu or (619) 306-2262.
