Table 5 Results from the customized MedEx system, CRF (all features), SVM (all features) systems, Simple Majority, Local CRF-based and SVM-based voting in 10-fold cross-validation: “m” stands for medication, “do” for dosage, “mo” for mode, “f” for frequency, “du” for duration, “r” for reason

From: Recognition of medication information from discharge summaries using ensembles of classifiers
