BACKGROUND There are several ways to achieve semantic linking between news stories. An important starting point is how a viewer perceives the broadcasts. Given two news stories our rst im-pression is their visual information.

WebAs shown in [2], for one-dimensional real-valued variables, the energy distance is linked to the non-distribution-free version of the Cramér-von Mises distance: D ( u, v) = 2 l 2 ( u, v) = ( 2 ∫ − ∞ + ∞ ( U − V) 2) 1 / 2. Note that the common Cramér-von Mises criterion uses the distribution-free version of the distance. Webdistance earth-movers-distance point-clouds python scipy.
