9. The method of claim 8 , further comprising normalizing the probabilities so that a sum of all the probabilities is 1.
8. The method of claim 7 , further calculating of probabilities of an “allowed” combination of a topic t i , a genre j k , a site genre js m and a lexical characteristic lex q , and “disallowed” one, as follows: M − =Σp(t i )·p(j k )·p(js m )·lex q , such that topic t i , a genre j k , a site genre js m and a lexical characteristic lex q correspond to disallowing marker m − ; and M + =Σp(t i )·p(j k )·p(js m )·lex q , such that topic t i , a genre j k , a site genre js m and a lexical characteristic lex q correspond to allowing marker m + .
