title: Implementing Bi-directional LSTM-CRF Network
body: <p>I need to implement a bidirectional LSTM network with a CRF layer at the end. Specifically the model presented in this paper, and train it.</p>

  <p>I want to implement it in Python preferably. Can anyone present some libraries or sample code as to how this can be done. I looked at PyBrain but couldn't really understand it.</p>
  
  <p>I'm also open to tool-kits in other programming languages.</p>
