LoPar is an implementation of a parser for head-lexicalised
probabilistic context-free grammars (see Carroll/Rooth).
LoPar can be used for
symbolic parsing with a context-free grammar (CFG)
statistical parsing with PCFGs and head-lexicalised PCFGs
training of PCFGs and HLPCFGs
Viterbi parsing
chunking
tagging
and more
You can download LoPar as a gzip-compressed tar file for either Sun/Solaris
or Intel/Linux
platforms. LoPar may be freely used for education, research and other
non-commercial purposes. More information on LoPar can be found in this paper.
