Unlike the models proposed by Brown et al. ( 1993b ) , this model is symmetric , because both word bags are generated together from a joint probability distribution .
but dictionaries are data too

The probability distribution trans ( ii , it ' ) is a word-to-word translation model . Unlike the models proposed by Brown et al. ( 1993b ) , this model is symmetric , because both word bags are generated together from a joint probability distribution . Brown and his colleagues ' models , reviewed in Section 4.3 , generate one half of the bitext given the other half , so they are represented by conditional probability distributions .
