Method Summary

void	addDice(java.util.ArrayList dice) add small random vector to the values of the edge weight table (table.txt) in the hope of better correlation
double	getCorrelation(java.util.ArrayList relatednessValues) compute correlation between relatedness results and gold standard see http://de.wikipedia.org/wiki/Korrelationskoeffizient
java.util.ArrayList	getRelatednessValues() write relatedness values of all word pairs in an arraylist, see LcComparator
void	getWeights() try different weights, keep the ones, which improve the correlation most
void	subDice(java.util.ArrayList dice) subtract the small random vector to the values of the edge weight table (table.txt) if the correlation got worse
