Classification results on the 1510 NE pairs with CL evaluation (in decreasing order according to the successfully classified pairs). Ratio (r) refers to the distribution of positive classes predicted by the kernel measured across the 5 corpora; TN/FN is the number of correctly/incorrectly classified NE pairs; e is 1510·(1−r), the expected number of negative class prediction projected onto the 1510 NE pairs.
