Q:Why is the maximum taken to calculate the ranking for a grouping,why not the sum?
A:Well,you can do it either way and both are wrong.If you take the sum,then you get the intersection twice.If you take the max,then you miss the difference.Which one to choose?Suppose somebody comes up with a new search term that is 10% of the original.If you take the max,nothing changes.If you take the sum then the ratings will rise 10%.So taking the sum will be an incentive for some to come up with all kinds of obscure terms for a language.That's why we decided to take the max.
