[SRILM User List] [External Sender] A modified count = 0

[Anna Bulusheva]

Hello,

I try to estimate a LM with modified Kneser-Ney discounting (without 
"-interpolate") and I cut my vocabulary by removing words with count < 
3. In my list of n-grams I have a n-gram "w1 w2", but I don't have any 
n-grams "* w1 w2". It means that a modified count of "w1 w2" = 0. So I 
don't understand how I must calculate prob("w1 w2"). Could you help me, 
please?

P.S. The order of my LM is 3 and if I use SRILM to estimate this LM then 
there is n-gram "w1 w2" with some probability.

Thank you,

Anna Bulusheva
