title: Using pre-annotated dataset to do NER on a custom entities in the IBM Cloud
body: <p>I've been searching the documentation for a way to use a pre-annotated dataset to do NER on a custom entities in the IBM Cloud.
  I haven't been able to find a way to do it. 
  Is it something that is possible to do with Watson Knowledge Studio and/or Natural Language Understanding ?
  Can you point me toward the right ressources ?</p>
  
  <p>Thanks in advance</p>
