title: Analyse the sentences and extract person name, organization and location with the help of NLP
body: <p>I need to solve the following using NLP, can you give me pointers on how to achieve this using OpenNLP API</p>
  
  <p>a. How to find out if a sentence implies a certain action in the past, present or future.</p>
  
  <pre><code>(e.g.) I was very sad last week - past
         I feel like hitting my neighbor - present
         I am planning to go to New York next week - future
  </code></pre>
  
  <p>b. How to find the word which corresponds to a person or company or country</p>
  
  <pre><code>(e.g.) John is planning to specialize in Electrical Engineering in UC Berkley and pursue a career with IBM).
  </code></pre>
  
  <p>Person = John</p>
  
  <p>Company = IBM</p>
  
  <p>Location = Berkley</p>
  
  <p>Thanks</p>
