9. The computing device of claim 8 , further comprising configuring the at least one processor to: store pre-determined shape descriptors corresponding to the at least one pre-determined machine generated work; compare a shape descriptor of the 2-dimensional plot to the pre-determined shape descriptors; calculate a center of mass and the shape descriptor of the 2-dimensional plot; and determine further, based at least in part on the comparing, that the textual work is machine generated.
