A collection of multi-label and multi-target datasets is available here. Even more datasets are available at the MULAN Website (note that MULAN indexes labels as the final attributes, whereas MEKA indexs as the beginning). See the MEKA Tutorial for more information.

The following text datasets have been created / compiled into WEKA's ARFF format using the StringToWordVector filter. Also available are train/test splits and the original raw prefiltered text.
