title: Clarification How CRF(Conditional random Field) works using examples
body: <p>I read different documents how CRF(conditional random field) works but all the papers puts the formula only. Is there any one who can send me a paper that describes about CRF with examples like if we have a sentence </p>
  
  <p>"Mr.Smith was born in New York. He has been working for the last 20 years in Microsoft company."</p>
  
  <p>if the above sentence is given as an input to train, how does the Model works during the training taking in to consideration for the formula for CRF?
  Smith is tagged as "PER" New York is as "LOC" Microsoft Company as "ORG".
