(A syntactic parser for CHILDES trascripts)
Institute for Creative Technologies, University of Southern California
MEGRASP is a dependency parser for identification of grammatical relations in child language transcripts in the CHILDES Database.
Warning: the part-of-speech tags used in the CHILDES database have changed since the parser was released! This means that MEGRASP will NOT WORK properly until I update the parser models. If you have the latest version of CLAN and the English lexicon for MOR, the parser will produce garbage.
MEGRASP v0.7 (released June 15, 2007)
· Mac OSX
Updated source code coming soon (if you want source code now,
you can get the code for my CoNLL-style dependency
After downloading and unzipping the archive for your platform, please look at the README file (README.txt in the Windows distribution) for instructions on running the parser.
