   abstract = {In this paper we evaluate the performance of multilabel classification algorithms on
the EUR-Lex database of legal documents of the European Union. On the same set of underlying documents, we defined three different large-scale multilabel problems with up to 4000 classes. On these datasets,
we compared three algorithms: 
(i) the well-known one-against-all approach (OAA); 
(ii) the multiclass multilabel perceptron algorithm (MMP), which modifies the OAA ensemble by respecting dependencies between the base classifiers in the training protocol of the classifier ensemble; and 
(iii) the multilabel pairwise perceptron algorithm (MLPP), which unlike the previous algorithms trains one base classifier for each pair of classes.
All algorithms use the simple but very efficient perceptron algorithm as the underlying classifier. This makes them very suitable for large-scale multilabel classification problems. 
While previous work has already shown that the latter approach outperforms the other two approaches in terms of predictive accuracy,
its key problem is that it has to store one classifier for each pair of classes.
The key contribution of this work is to demonstrate a novel technique that makes the pairwise approach feasible for problems
with large number of classes, such as those studied in this work.
Our results on the EUR-Lex database illustrate the effectiveness of the pairwise approach and the efficiency of the MMP algorithm.
We also show that it is feasible to efficiently and effectively handle very large multilabel problems.},
