> We need some pre-processing to make it easier for OpenNLP to deal with hyphens, for instance this is an example of a real PDF:
> Sparse RBMs and sparse auto-encoders
> (RBM, SAE): In some of our experiments, we
> train sparse RBMs (Hinton et al., 2006) and
> sparse auto-encoders (Ranzato et al., 2007; Ben-
> gio et al., 2006), both using a logistic sigmoid non-
> linearity g(W x + b). These algorithms yield a set
> of weights W and biases b. To obtain the dictio-
> nary, D, we simply discard the biases and take
> D = W ⊤ , then normalize the columns of D.
> The current implementation return a TextAnnotation with entity-type = Person for the mention "Ben -" (which is then matched to "Ben Stiller" :P).
