[SRILM User List] LM whose counts are multiplied

[shinichiro.hamada]

Hello, all.

I want to make a language model with data which have fraction counts. But
not all smoothing method can handle them, so I'll try to multiply each count
by 10 and make it integer by rounding.

I did a preliminary experiment.

Files:
* count-file with integers : a.count
* the file whose counts are multiplied by 10 : b.count

Command:
ngram-count -read a.count -order 3 -lm a.lm -wbdiscount -wbdiscount1
-wbdiscount2 -wbdiscount3 -interpolate
ngram-count -read b.count -order 3 -lm b.lm -wbdiscount -wbdiscount1
-wbdiscount2 -wbdiscount3 -interpolate

I expected same language models are generated, but they differed. Why?
Followings are their heading parts.
