[SRILM User List] Interpolate trigram Probabilities to an n-gram LM

[Md. Akmal Haidar]

Hi,

1. Is it possible to interpolate some trigram probabilities (say they are in file t.txt) with an n-gram LM ? 
SRILM gives results with the warning (no bow for prefix of trigram of t.txt).
-lm n-gram.lm -lambda .9 -mix-lm t.txt -ppl test.txt 

2. When the trigram probabilities in t.txt changes (newt.txt), the results are exactly the same as above.  
-lm n-gram.lm -lambda .9 -mix-lm newt.txt -ppl test.txt

Is above interpolation is OK?Is there any other methods that are required to interpolate these trigram probabilities to an n-gram LM?


Format of t.txt/newt.txt
\data\
ngram 3=242
\3-grams:
....
\end\

Thanks
Best Regards
Akmal
