Best-F1 values table of Fig 2.

Jaffe + Sectors (J + S) constantly outperforms all the other measures on both Target and Pair Prediction and for all class imbalances. On the other hand, Euclidean Distance (EU) is always the worst performing. Due to the normalisation with respect to the random case, the Best-F1 values increase with the class imbalance, but the ranking of the different measures remains nearly the same.
