hi rasul
there is an implementation of the GHKM extract algorithm in
training/phrase-extract/extract-ghkm
the program
training/phrase-extract/extract-rules
can extract generic string-to-tree and tree-to-string grammar. It can
also extract SAMT-style grammar.
Since these algorithms are reimplementations of existing research no-one
written about them. You should just read the original papers on
SAMT/GHKM/syntax models etc.
In all these cases, the decoder algorithm is the same (CKY+). Phil
Williams has also implemented the Scope 3 algorithm by Hopkins et al.
The Moses syntax decoder was also written to do another tree-to-string
model which I wrote about in
http://aclweb.org/anthology-new/W/W10/W10-1761.pdf
A better explanation for it is in my thesis
www.statmt.org/~s0565741/ddd.pdf
