Exploring NLP concepts using Apache OpenNLP

Introduction Some time ago I came across this life-cycle management tool (or cloud service) called Valohai and I was quite impressed by its user-interface and simplicity of design and layout. I had a good chat about the service at that time with one of the members of Valohai and was given a demo. Previous to that I had written a simple pipeline using GNU Parallel, JavaScript, Python and Bash - and another one purely using GNU Parallel, and Bash. I also thought about replacing the moving parts with ready-to-use task/workflow management tools like Jenkins X, Jenkins Pipeline, Concourse or Airflow but due to various reasons I did not proceed with the idea.
