Finally, the conditional probability distribution P (f |p) is estimated as follows: where freq sni (p, r, e) stands for the frequency of the expression e appealing with the phrase p in relation r within the snippets for p. The weight for features P (f ) is estimated using a static corpus based on the following equation: where freq cp (r, e) indicates the frequency of the expression e appearing with something in relation r within the given corpus.
