A simplified definition of scaling is converting a number from one range to another range based on proportion. For a more thorough definition, see <a href="https://en.wikipedia.org/wiki/Feature_scaling" rel="nofollow" class="external text">the Wikipedia page on feature scaling</a>

A simplified definition of ranking is assigning a number based on its order in a population of numbers. For those familiar with a school setting, this is "grading on a curve".

Note that #2 is recursive (a page will have a high score only if it is linked to by many pages). For more info, a good starting point is <a href="https://en.wikipedia.org/wiki/PageRank" rel="nofollow" class="external text">the Wikipedia page on PageRank</a>.

After XOWA calculates the PageRank, XOWA then scales this score in a range of 0 to 1,000,000
