title: Extract the most relevant location corresponding to a keyword
body: <p>I'm implementing an application that tracks the locations of Australia's sharks through analysing a Twitter dataset. So I'm using shark as the keyword and search for the Twitts that contains "shark" and a location phrase.  </p>
  
  <p>So the question is how to identify that "Airlie Beach at Hardy Reef" is the one that is correlated to "shark"? If it's possible, can anyone provide a working code of Python to demonstrate​? Thank you so much!</p>
