Efficient Context-Free Grammar parser, preferably Python-friendly

Question

I am in need of parsing a small subset of English for one of my project, described as a context-free grammar with (1-level) feature structures (example) and I need to do it

Answer 1

I would recommend using bitpar, a very efficient PCFG parser written in C++. I've written a shell-based Python wrapper for it, see https://github.com/andreasvc/eodop/blob/master/bitpar.py
