If we subsume the language-independent categories, because they are randomized and treated similarly in surrogate generation, we get comparable outcomes for all experiments with the PIR system with an F 1 score around 90.00.
language-dependent categories, with the exception of DATEs, which accomplish equivalent results for nearly all experiments, too, consistently perform worse compared to training and testing on the same corpus, especially regarding ORGanizations, CITYs and STREETs.
