  -Authority means how knowledgeable people are on a single topic. We use authority to calculate the credibility score of a Factlink.

   <h2>Authority calculation</h2>
   
  
positive.code:   <p>
      After we calculate how much authority you gain from your Factlink we spread this over the topics it belongs to, according to our users. So for instance, let's say you created a Factlink about Michael Jackson and it gains you 4 authority. If this Fact is in 10 Michael Jackson channels, 20 Music channels and 10 Eighties channels, you will gain 1 authority on Michael Jackson, 2 on Music, and 1 on Eigthies.

    <h2>Calculating how much you know about a fact</h2>
    <p>
      Finally, to calculate how much you know about a certain fact we take the weigthed average of your authority on the topics this fact is about. So if a fact is in 10 Ruby channels, 20 Programming channels and 10 Rails channels, and your authority on Ruby is 10, on Programming 5 and on Rails 20, your authority on this fact is (10*10+5*20+10*20)/40 = 10.

negative.code:   <h2>Factlink classification</h2>
  
    <p>
    When you put a Factlink in a channel you are classifying a Factlink. Since we think this is important we reward classification with authority on the subject. We do this in two (direct) ways:
    </p>
  
    <ol>
      <li>When you add a Factlink to a channel, you get a little authority (0.1) on the topic the channel is about. Since we really need others to confirm your authority, the amount of authority you can earn is limited to 4 authority points.</li>
      <li>When someone follows your channel, you get 1 authority for the topic that channel is about.</li>
    </ol>
