Training FlexTag Most other trainable taggers only support one input format and users are supposed to transform their data in the required format.
in order to make this simplicity possible, FlexTag relies on DKPro Core 1 (Eckart de Castilho and Gurevych, 2014) for preprocessing and model loading, and DKPro TC (Daxenberger et al., 2014) for feature extraction and classification.
