Classification results on the 219 PE pairs with CV 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; TP/FP is the number of correctly/incorrectly classified PE pairs; e is 219·r, the expected number of positive class prediction projected onto the 219 PE pairs.
