Method Detail

normalize

Scoreable normalize(java.util.List<? extends Scoreable> scoreableList,
                    Scoreable bestToken)

Normalizes the scores of a set of Tokens.

Parameters:

scoreableList - The set of scores to be normalized

bestToken - The best scoring Token of the above mentioned list. Although not strictly necessary it's included because of convenience reasons and to reduce computational overhead.

Returns:

The best token after the all Tokens have been normalized. In most cases normalization won't change the order but to keep the API open for any kind of approach it seemed reasonable to include this.
