Each topic is associated with a probability vector, which quantifiesthe probability of the different terms in the lexicon for that topic.Let t1 ...td be the d terms in the lexicon. Then, for a documentthat belongs completely to topic Tj , the probability that the termtl occurs in it is given by P(tl|Tj ). The value of P(tl|Tj ) is anotherimportant parameter which needs to be estimated by the topicmodeling approach.
