title: Extracting data from social media networks
body: <p>I am trying to create a Web application which will be able to analyze social media profiles. The social networking sites I want to analyze are Facebook, Twitter and YouTube. </p>
  
  <p>I would like to use Data Extraction tool APIs as my back-end. Many of the tools I have found are either expensive or do not work. </p>
  
  <p>I have researched on the Facebook, Twitter and YouTube API among others such as NodeXL.</p>
  
  <p>Would anyone suggest any free available APIs which I could use please? Preferably ones which would not be too difficult to implement.</p>
