> Adding brown clustering features. These features have shown to provide very
> good results (Ratinov and Roth 2009, Turian et al 2010). The hierarchical
> clusters can be created with https://github.com/percyliang/brown-cluster
> tool.
> The Brown features duplicate each active token feature by each of the paths
> in the class we extract as features from the clusters.
