title: Machine Learning for repetitive form filling
body: <p>I'm trying to use machine learning algorithms for repetitive form filling.
  Here is a picture to illustrate that a little bit.</p>

  <p>If you enter values in field A and B i would like to have a suggestion for field C. 
  For this case i really would like to implement a Machine learning algorithm so that the system stays really flexible and only makes suggestions by the knowledge that was build.</p>
  
  <p>I've already started reading programming collective intelligence and Artificial intelligence a modern approach. I also started to play around with Weka a little bit and found a pretty good <a href="http://research.microsoft.com/pubs/78662/alimeekpredictivemodelsofformfillingtechreport.pdf" rel="nofollow noreferrer">microsoft research paper on my problem</a> too. But my main problem is that I can't really identify what algorithm group I should use. I'm primarily looking at Descision trees like C 4.5 but I'm not sure if this is the right way. Could you please give me any suggestions on my problem?</p>
