I assume this is a line from the LM.
It is NOT a class-membership probability.   The N-gram model can have a 
mix of word and class labels.   A word label simply represents a class 
consisting only of the word itself.  Therefore, the above line means 
that class CLASS-00021 has probability 10 ^ -0.7027302 when the previous 
word is آتِدْيُونْ .

The class membership probabilities are stored in the file that you 
specify with ngram -classes .
