Hello,
Does someone have some support to this (found in the doc) :
Maximum Phrase Length
The maximum length of phrases is limited to 7 words. The maximum phrase
length impacts the size of the phrase translation table, so shorter
limits may be desirable, if phrase table size is an issue. Previous
experiments have shown that performance increases only slightly when
including phrases of more that 3 words.
Summary
--max-phrase-length -- maximum length of phrases entered into
phrase table (default 7)
If there is no major improvement above 3, why is the default 7, and is
there a benchmark somewhere ?
Thanks
Vincent.
