one unit of precision for an increase of one unit of recall,but will not sacrifice another unit of precision for a further unit increase in recall,i
...R 1,P 1 >R,P but R 1,P >R 2,P 1 We conclude that the interval between R 1 and R exceeds the interval between P and P 1 whereas the interval between R 1 and R 2 is smaller
...Finally,we incorporate into our measurement procedure the fact that users may attach different relative importance to precision and recall
...Definition 6
...Can we find a function satisfying all these conditions?If so,can we also interpret it in an intuitively simple way?The answer to both these questions is yes
...The scale functions are therefore,[[Phi]]1 P [[alpha]]1 P,and [[Phi]]2 R 1 [[alpha]]1 R
...We now have the effectiveness measure
