title: How to detect standard language constructions, like negations or questions?
body: <p>There are some words, phrases and language constructions which should be available without any additional training or definition. At least, I was expecting to have that from NLP.</p>
  
  <p>For example:  </p>
  
  <p>How to detect negations?<br>
  - no, I don't need gift card<br>
  - no gift card<br>
  - gift card is not required  </p>
  
  <p>How to detect that the sentence is question and what type?<br>
  - How many colors do you have?<br>
  - When will you call me?</p>
  
  <p>Do I need to cover all that with my custom entities?</p>
