Distributional Term Set Expansion
Table 1: Average number of positive examples found per iteration of the term set expansion method, based on ten random initialization with five positive and five negative examples. Simple Margin using an RBF kernel is consistently the best expansion method for all term sets.

The results are displayed per tested term set, expansion method, and underlying distributional model used. It is evident from this table that, generally, Simple Margin using an RBF-kernel outperforms the other expansions methods. This is true for all term sets, and almost all combinations of term sets and distributional models tested.
