Reporter: Rodrigo Agerri
Assignee: Rodrigo Agerri
Priority: Minor
Fix For: 1.6.0
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.
