title: Machine learning example- determine if a website is business or personal
body: <p>I have a machine learning problem.  I am given a long list of domains and I have to figure out which are ecommerce websites and which are personal websites.  It is kind of a difficult problem because I do not have any training data to work with.  I have come up with a couple ideas:</p>
  
  <ol>
  <li><p>Go through a couple hundred of these websites manually to tell if they are business or personal and develop a training set this way (Long and boring!).</p></li>
  <li><p>Crawl these websites and search for some keywords eg. "Buy Now", "Price", "Credit Card". etc.</p></li>
  </ol>
  
  <p>Does anybody have any other approaches?</p>
  
  <p>Thanks</p>
