Memory - this read in the phrase table into memory. For phrase-based model
Binary - a phrase table is converted into a 'database'. Only the
translations which are required are loaded into memory. Therefore,
requiring less memory, but potentially slower to run. For phrase-based model
OnDisk - reimplementation of Binary for chart decoding.
SuffixArray - stores the parallel training data and word alignment in
memory, instead of the phrase table. Extraction is done on the fly. Also
have a feature where you can add parallel data while the decoder is
running ('Dynamic Suffix Array'). For Phrase-based models. See
http://homepages.inf.ed.ac.uk/miles/papers/naacl10b.pdf
ALSuffixArray - Suffix array for hierarchical models. See
http://www.cs.jhu.edu/~alopez/talks/mtm2008-lopez.pdf
FuzzyMatch - Implementation of this paper
http://homepages.inf.ed.ac.uk/pkoehn/publications/tm-smt-amta2010.pdf
SCFG - Like 'Memory' but for chart decoding
Hiero - like SCFG, but translation rules are in standard Hiero-style format
Compact - for phrase-based model. See

Could somebody give me a A a detailed explanation ?
How were they implemented in moses ?
Thank you in advance !
