LIBSVM Data: Multi-label Classification

Recently multi-label classification has been an important topic. Currently there are very few publicly available data sets. We tried hard to collect the following sets. Labels are in the beginning of each line and separated by commas.

• Preprocessing: We combine all binary classification problems into a multi-label one.
