[Corpora-List] A question About Chomsky normal form

[Heshaam Feili]

Dear Colleguese,
I need a relateively large bracketed data set with CNF format to test it on
Algorithms like inside-outside (lari and young 1990). I choosed NEGRA data
set and trying to change it to CNF format.
After the changing to CNF format, a lot of non-terminals will be created
because of binarization ... so the algorithm (inside-outside) failed.
What can I do in order to overcome this problem?
Best
